In the context of cultural routes, in order to achieve overall protection of industrial heritage, the European Route of Industrial Heritage (ERIH) was established to organize and promote the entire European industrial heritage. The conservation and utilization of Chinese industrial heritage are currently dominated by individual cases, which limits their potential to contribute to regional sustainable development. There is an urgent need of a conservation system at the regional or national level, to ensure that Chinese industrial heritage conservation effectively contributes to regional sustainable development. This study considers the industrial heritage of China built between 1840 and 1978 to establish the Chinese Industrial Heritage GIS Database (CIHGD). The analysis shows that the distribution of China's industrial heritage is mainly concentrated in the eastern and southern coastal areas, and the industrial heritage has formed three key regions, 14 key cities, and important railway and water systems located in eastern China. The CRIH facilitates the holistic conservation of China's industrial heritage and provides basic data for future research on China's industrial heritage. The objective of this study is to promote the establishment of an information-based management system for industrial heritage in China, and to explore the value evaluation, protection system, and regional tourism of industrial heritage from a national perspective in China.

Ecosystems provide various goods and services to society and their valuation is among the main objectives of the concept of ecosystem services (ES). The mapping of ecosystems is the main building block of the whole process of the Mapping and Assessment of Ecosystems and their Services (MAES). The analyses of the ecosystem data produced during the implementation of the national methodology for mapping ecosystems in Bulgaria (MAES BG) reveal some problems that may cause confusion in cases of integrated assessment of all ecosystem types. In this paper, we present an approach that enables formulation of a uniform spatial dataset based on the mapping of the main ecosystem types, that can be used for mapping of ES at a river basin scale. It has been applied to the upper part of the Ogosta River basin and the result is a topologically correct uniform spatial data layer. The approach gives one possible solution to problems related to the different sources of information and the discrepancies between ecosystem types in the national mapping of ecosystems in Bulgaria. It is based on the use of a uniform spatial framework that outlines the ecosystem types and sets the initial database for further mapping. This ensures a topologically correct spatial dataset for the ecosystems and a background for further updates for each ecosystem at the different levels of MAES typology. The most appropriate spatial basis for the territory of Bulgaria is the database for the physical blocks of the Ministry of Interior. Its application to the studied river basin gives encouraging results and can be used as an example for similar areas. Further development of the approach will ensure the mapping of the forest ecosystems at level 3 of the MAES BG typology and more precise delineation of the grassland, heathland, freshwater, and sparsely vegetated ecosystems.

In the Republic of Serbia, the assessment of losses and damages after a natural disaster is based on a document adopted in 1987 during the Socialist Federal Republic of Yugoslavia. Although of exceptional quality in its structure and purpose, the Instruction on a Uniform Methodology for Assessing Damage from Natural Disasters has outlived its time and it is necessary to align the document with today's needs. The Government of the Republic of Serbia has formed a working group with the task of drafting a unique methodology for assessing damage from natural and other disasters, which is also in line with international standards and practice. In parallel with this activity, engineering associations and groups of experts are working on technical instructions for each of the natural hazards, which will be compatible with the unique methodology to be adopted by the Government of Serbia. The earthquake that hit the Republic of Croatia in 2020 pointed out a number of shortcomings in national documents, and then the international methodology "Post Disaster Need Assessment" was used to assess the damage. The paper presents the experiences of a team of experts from Serbia who paid an official visit to the Republic of Croatia after the earthquakes in Petrinja and Zagreb and gained significant experience from the field in damage assessment, as well as through cooperation with crisis headquarters formed after the earthquake.

Ensuring high quantity and quality of water for humans is becoming more important because of the water supply risks in extreme climates. With increasing urbanization, urban water resource management is becoming increasingly important. The hydrologic analysis of water supply pipelines can help decision-makers understand water pressure, flow rate, water quality, and possible leakages, extending feasible strategies for sustainable development and smart cities. In this study, an improved urban hydrologic analysis model was built by integrating the connectivity of graph theory and the geographic information system (GIS) database. The Neihu Division of the Taipei Water Department in Taiwan was taken as an example to explain the proposed process and method, and 15,131 confluence data items were used to analyze the differences between the proposed method and WaterGEMS. The results show that of the total head parameters, 72% had zero differences, 28% had a difference of less than 1 m, and about 99% of the confluences had a water pressure difference of less than 1 m. The comparison of 120 on-site water pressure measurements showed that about 85% of the confluences had an error of less than 20%. The above results demonstrated the applicability of the proposed method for water resource management on similar scales and its benefit for the development of smart cities. [ABSTRACT FROM AUTHOR]

The Giardino Inglese of the Reggia di Caserta is among the most important and ancient gardens in Italy. A survey of vegetation was carried out, and a collection catalogue was produced using updated nomenclature and Angiosperm Phylogeny Group (APG) IV criteria classification. The data from survey were georeferenced in a GIS environment. For each species, the conservation status at world level as per International Union for Conservation of Nature (IUCN) and Botanic Gardens Conservation International (BGCI), the phytosanitary status, and the number of individuals were evaluated. Two synthetic indices were created that allow the evaluation of collection's erosion risk (ER). In the analysis, each species is placed in a specific quadrant indicating its level of erosion risk, and a priority score (PS) allows the evaluation of the priorities of any conservations interventions. The collection consists of 235 species, and approximately 65% of these are reported in IUCN Red List. 1671 individuals were registered. The database and the ER assessment allows the future development of tools for the management of the site. The Giardino Inglese is a garden of collections and a conservation basin for historical and monumental specimens of many species, some of which are subject to protection. [ABSTRACT FROM AUTHOR]

The aim of this study is to find a suitable methodology for planning the locations of intermodal terminals in an urban transit context. The location planning approach, which has been developed and makes this possible, consists of three phases. The first phase is the making of the geographic information system (GIS) database which enables determining the potential locations of intermodal terminals. For every potential location of the terminal, the number of citizens gravitating to a certain terminal is calculated, which at the same time represents the output from the first phase of the model. The second phase uses an optimization algorithm in order to determine the locations of the intermodal terminals. The optimization algorithm provides several solutions for a different number of terminals, and such solutions need to be evaluated. The main contribution of this research is in upgrading the location planning approach by introducing an additional step in assessing the solutions obtained by the optimization algorithm.

Many studies highlight the benefic influence of forests on the quality of environment. There is an interest for identifying the pretability of a certain territory for representative forest tree species according to their pedological, hydro-climatic and geomorphological characteristics. The main purpose of this endeavour is the enhancement of a territory's economic quality as well as the highlighting of the forest's stabilizing role which is determined by new forest plantations with well-defined purposes. This study aims at proposing a quantitative model based on correlation equations between forest favourability classes and ecological factors/determiners for the main forest species from the hill bioclimatic zone. By using geographic information system (GIS) spatial analysis and integrating a specific digital database, forest favourability classes were identified for eight of the most common forest species from Someşul Mare Hills: pedunculate oak, Turkey oak, Hungarian oak, hornbeam, linden, sycamore tree, cherry tree and beech. The main focus was laid on developing and obtaining the necessary digital database for the GIS spatial analysis model and on the work stages of creating a GIS model which could be implemented in areas with similar characteristics.

- Abstract
There is a great need for an efficient geographic information system (GIS) implementation in interdisciplinary domains for providing useful information for scientific and managerial processes of further improving land-use planning and decision making in horticulture. The main goal of this study was the creation of a digital map and GIS application for the Fruit Research Station in Cluj-Napoca, North-Western Romania. The benefit of this implementation is a fully integrated land information system, where information is accessed omnipresent for processing, value adding and further analysis. The created model is as a modern solution for obsolete analogue maps, sketches, inventory and land records that are usually unreliable and poorly represented in agricultural productive units. Using the created GIS database and spatial analysis there were obtained a very useful orchard mappings that incorporate management and economical attributes essential in land planning. Future focus and development will be mainly on system maintenance, including system enhancement and upgrading rather than to create a new systems. Under the constant pressures of urban sprawl and land degradation in this area, the paper conducts towards a guideline and model for an effective use of land resources to the best advantage and capacity.

Karstified dolomitic formations situated in the Far West Rand goldfield of the Witwatersrand Basin constitute a significant groundwater resource in semi-arid South Africa and would be of strategic importance for alleviating the increasing water stress in nearby metropolitan areas. The deep-level gold mines operating below the dolomites have suffered from large volumes of dolomitic groundwater flowing into the mine voids, rendering mining both expensive and hazardous. In order to secure safe and economical mining, the overlying dolomites were dewatered. Here we review research over 60 years, conducted in three of the four major dolomitic compartments affected by dewatering. After more than six decades of research, these aquifers are arguably the most investigated karst systems in South Africa, and possibly worldwide. The data generated are, in many respects, unique, as many measurements can never be repeated, covering stochastic events such as a major water inrush into mine workings and some of the most catastrophic sinkhole developments ever recorded. Given the potential value for improving the understanding of general and local karst hydrogeology, our main goal for this paper is to alert the scientific community to the existence of this resource of mostly unpublished data and research. A no less important aim is to support a systematic collation of these studies which are in danger of being irretrievably lost as mines increasingly close down. Ecological and economic impacts of the flooding of mines in and around Johannesburg emphasise the lack of reliable historical mine data to optimally address the matter. We provide the first comprehensive, yet not exhaustive, overview on the existing studies, briefly discussing scientific content as well as obstacles for utilising the scattered, and often non-peer reviewed, information sources.

La caracterización edafoclimática de los suelos es un proceso que contribuye a la planificación de las siembras con mejores perspectivas rentables, siendo el punto de partida de la actividad productiva agropecuaria. El objetivo fue generar una base de datos geoespaciales integrada de condiciones edafoclimáticas del distrito de Cacatachi, de consulta dinámica a través de mapas temáticos como de fisiografía, capacidad de uso, características físicas y químicas de suelos y de uso actual de las tierras. Para ello se empleó un software GIS utilizando información de instituciones públicas que iniciaron el proceso; asimismo, la metodología de trabajo tuvo dos etapas, a nivel de gabinete y a nivel de campo. El resultado fue la base de datos Quantum GIS (QGIS), que facilita el manejo de la información edafoclimática, con 104 mapas en detalle, cuyas representaciones espaciales exponen la caracterización de las zonas estratificadas en el proyecto, donde se hicieron las calicatas, de los cuales se hicieron los análisis químicos, físicos y biológicos de los horizontes identificados en los perfiles. La información edafoclimática generada nos aproxima a una microzonificación en detalle, que se convierte en herramienta orientadora de las siembras de cultivos, en función a las potencialidades nutricionales, fisiográficas y climáticas de los suelos, segmentados en sectores productivos.

Hazardous convective weather events (HCWE), such as heavy rainfall, large hail, squalls and tornadoes, are one of the substantial sources of natural emergencies in Russia. The territory of the Central Federal District (CFD) is characterized by the highest population density in Russia. On the one hand, this leads to increased risks associated with HCWE, but on the other hand, it provides the possibilities for collecting the most detailed information on them (including the events missed by the observation network and reported based on damage assessment). In this study, we consider the structure and information content of the GIS database of HCWE for the territory of the CFD. The main advantage of the developed database comparing with existing analogues is its structure, which includes information on both the events themselves and their consequences, and the conditions of their occurrence. This includes, in particular, the characteristics of meso-scale convective systems (convective storms) based on the images from meteorological satellites and diagnostic variables characterizing the atmospheric environments according to the data from ERA-5 and CFS reanalysis systems. Also, the developed database is associated with previously published databases on tornadoes in Northern Eurasia and large-scale windthrow events in European Russia. At present, we compiled the data on more than 2,000 cases of HCWE in the CFD for the period 2001–2020, most of which were reported based on damage assessment. The open-source PostgreSQL DBMS is used to manage and edit the database. Open access to the database on the Internet is implemented through an online web map service available at http://convective-storms.psu.ru/.

Tracing with artificial tracers is a research method that gives very good results in examining the direction and characteristics of groundwater flow in karst aquifers. The first mention of such experiments in Slovenian karst dates back to history and the beginnings of their use in the water resources management process in the first years of the 20th century. From that point on, more than two hundred tracer tests were carried out in Slovenian karst. Unfortunately, their results often remain hidden in internal reports in the archives of implementing organisations and are very difficult to access. The search for published results is also a time-consuming process, despite the possibilities of the use of search engines and key words. Due to the need for a systematic and rapidly accessible digital inventory of the tracer tests results, such inventory was designed and is now freely accessible in the Environmental Atlas (Atlas okolja), the spatial information system of Slovenian Environment Agency. In the database the results of 231 available tracer tests have been assembled, arranged and georeferenced. The article describes the data set concept, the process of collecting, verifying and evaluating data and the method of their transformation into a GIS database. Two points layers (injection site and sampling site) and one line layer (linear connection between both sites) were created. Symbology of line layer varies with different type of connection between injection and sampling site. By clicking on an individual element, selected data on the tracer test are displayed, and most of them are also accompanied by a copy of the data source (articles, reports). In this way it is possible to obtain more detailed information about the tracer test and its results. The database also provides a possibility of various comparative analyses. The article shows results of some of the basic statistical analyses in which the purpose and implementation of tracer tests, used tracers, characteristics of injection and sampling sites, and characteristics and velocities of groundwater flow connections were compared. It also provides an overview of the results of the tracer tests carried out within individual groundwater bodies. On the basis of the status identified, the locations for new tracer tests are proposed.

- Abstract
The Mociar forest is a site of interest for community, because of the occurrence of Quercus robur specie, on extended areas. The trees have over 300 years of age, and there, a series of problems are identified. They are connected to the drying of some individuals belonging to the mentioned species, but also to drying of younger sessile individuals (aged about 40 years). In this way, of great importance is the identification of the environmental factors, which lead to the degradation of the present forestry species, and development of a study that recommends the foundation of plantations with species resistant against environmental conditions, which characterize the Mociar Forest. Our study aims to perform a classification by classes of forestry favorability, function of limitative environmental factors: annual mean temperature, annual mean precipitations, number of days with temperatures >10° C, excess of precipitations, useful edaphic volume, etc. In this way, our study also aims to obtain a global image of the classes of favorability for twelve forestry species, Quercus Robur (common oak), Quercus peduncuiflora (grayish oak), Robinia pseudoacacia (acacia), Quercus cerris (Turkey oak), Quercus frainetto (Italian oak), Fraxinus excelsior (common ash), Carpinus betulus (common hornbeam), Acer pseudoplatanus (sycamore), Tillia codata (small leaved linden), Prunus avium (wild cherry), Quercus petraea (sessile oak), Fagus sylvatica (common beech), Abies (fir), respectively.

Land use is a physical property of the land which gives information regarding the function of the land resources. Furthermore, a land use map functions by relaying the information of land use within the area visually. Langkawi Island being one of the main attractions in Malaysia has undergone rapid development due to tourism industry. Therefore, this paper studies the land use changes in the Langkawi Island over the period of 12 years. Land use maps were derived by analyzing temporally available satellite imageries of the area. Subsequent Landsat imageries of the year 2006, 2012 and 2018 were processed in ENVI using Normalize Difference Built-Up Index (NDBI) and supervised classification. The land use classes obtained were categorized according to the SWAT land use classification namely FRSE, AGRL, URBN, UCOM, UIDU, and UTRN. The analysis the land use maps provided the statistical comparison for the changes in the land use classes around the Langkawi Island. The changes in the area has increased especially in the urban categories. This research will provide an overview for the stakeholder to analyze the current land use of the Langkawi Island and develop future land use planning. Moreover, the map can be used for a functional land use input in the SWAT modelling and provide a temporal GIS database on the land use of Langkawi Island.

Historical narratives in Upper Senegal largely center on precolonial statecraft, long-distance trade, and ethno-religious mobilization. Drawing on the perspective of political ecology, we examine how these regional processes intersected with village life through local relations to land. Specifically, we chart the long-term dynamics of settlements and their catchments along the Falemme River between the states Gajaaga and Bundu, centered on the Senegal confluence, and a shifting frontier with the non-state societies of Bambuk to the south. This involves first integrating site data from our independent archaeological surveys of the Lower and Middle Falemme study areas into a GIS database for regional analysis of settlements patterns during the second millennium AD. We then compare these patterns with site catchments for surface soils classified from multispectral satellite imagery (Landsat 8 OLI-TIRS) to model everyday access to cultivable land. Our results challenge state-centric narratives of Upper Senegal by suggesting that everyday experiences of village life along the Falemme River were more firmly grounded in local concerns for land and subsistence production than in regional politics of statecraft and frontier.

We describe and share reconstructed data of the historical railway network of Galicia and Austrian Silesia – two regions of the Habsburg Empire that covered more than 80 000 km2 that are currently divided among Czechia, Poland and Ukraine. The network dataset includes the times of railway appearance and of the most dynamic development until 1914, which marked the outbreak of the First World War. Most of the lines were reconstructed based on OpenStreetMap data, and the lines, which were closed down between 1914 and 2019 and are no longer available in spatial datasets, were reconstructed based on high-resolution satellite imagery and historical maps. Altogether, the network dataset covers nearly 5000 km on 127 lines. The data are accompanied by a set of attributes, i.e. the year of construction, length, starting point, finish point, and type (normal, narrow-gauge, etc.), and are available for download in the shp format.

Several relevant collapses of historical urban walls happened in Tuscany in the last ten years, due to rainfalls. The wide extension of the walls, with difficulties of proper monitoring, joined with lack of maintenance, contributed to the failures. This recalled the attention on their vulnerability, in view to ensure a proper safety level and appropriate cultural heritage protection. In this paper, a method of extensive and quick structural survey to identify the mechanical characteristics of an historical urban wall path is proposed. It is based on geographic method of management of the territory (GIS database, satellite data). The data are obtained throughout a discretization of the walls in a wide set of vertical sections. A reduced subset of sections is directly surveyed, while the others are indirectly identified via numerical procedure, with the help of GIS data. A specific form to take note of the most relevant features is edited. The method is tested on the entire perimeter of the Middle Age walls of Volterra (2,6 km), affected by two relevant collapses in 2014. The procedure of survey is conceived to perform structural analysis to evaluate the vulnerability to landslides and earthquake risks, in view to determine restoration strategies and consolidation or monitoring programs.

The Loch Lomond Stadial (LLS) was an abrupt period of renewed cooling between 12.9 and 11.7 ka and has long been associated with the regrowth of glaciers in much of upland Britain. Mapping the glacial landforms associated with this period has been undertaken for over a century, but in a non-systematic nature and at specific locations. In this paper, glacial geomorphology associated with the LLS in Britain has been compiled from the published literature into a glacial map and accompanying geographical information system database that is available electronically as supplementary information. A variety of scales have been used to best represent the evidence in the database. Map A is at 1:310 000; B, C, D, E, F, J, L, M and O are at 1:175 000; K, N, P are at 1:100 000 and G, H and I are at 1:50,000. The database contains over 95,000 individual features, which are organised into thematic layers and each attributed to its original citation. The evidence includes moraines, drift and boulder limits, drift benches, periglacial trimlines, meltwater channels, eskers, striations and roches moutonneés, protalus ramparts and ice-dammed lakes. Creation of this database overcomes the drawbacks posed by the non-systematic nature of previous mapping output from studies of LLS glaciation. It is intended to be a catalyst for future research in this area, with especial significance for regional palaeoglaciological and palaeoclimatic reconstructions of the Younger Dryas and numerical modelling.

The Athenian Basin is a very interesting area from an archaeological point of view, since it is inhabited from Neolithic time. The human impact on the landscape is shown by the ancient constructions such as the Long Walls and the canalization of the rivers in the area of the Athenian Basin and Piraeus. The aim of the study is to detect the paleogeographical evolution of this area. In order to manipulate all the available information obtained from literature review (topographic maps, geological maps, ancient maps and references) and the stratigraphic data from 227 boreholes from the Athenian Basin, a GIS database was established. After the interpretation of the stratigraphy from the boreholes, six lithostratigraphic units were defined. Maps and 3D models were designed to represent the succession of the lithostratigraphy of each period. Paleogeographic maps were created in order to represent the landscape for each lithostratigraphic unit of the Athenian basin, and extract results for the temporal and spatial changes of the paleo-landscape and the involvement of the human impact on the depositional process in the Athenian Basin during Holocene.

After a big karst sinkhole happened in Jili Village of Guangxi, China, the local government was eager to quantitatively analyze and map susceptible areas of the potential second-time karst sinkholes in order to make timely decisions whether the residents living in the first-time sinkhole areas should move. For this reason, karst sinkholes susceptibility geospatial analysis is investigated using multivariate spatial data, logistic regression model (LRM) and Geographical Information System (GIS). Ten major karst sinkholes related factors, including (1) formation lithology, (2) soil structure, (3) profile curvature, (4) groundwater depth, (5) fluctuation of groundwater level, (6) percolation rate of soil, (7) degree of karst development, (8) distance from fault, (9) distance from the traffic route, and (10) overburden thickness were selected, and then each of factors was classified and quantitated with the three or four levels. The LRM was applied to evaluate which factor makes significant contributions to sinkhole. The results demonstrated that formation lithology, soil structure, profile curvature, groundwater depth, ground water level, percolation rate of soil, and degree of karst development, the distance from fault, and overburden thickness are positive, while one factor, the distance from traffic routes is negative, which is deleted from LRM model. The susceptibility of the potential sinkholes in the study area is estimated and mapped using the solved impact factors. The susceptible degrees of the study area are classified into five levels, very high, high, moderate, low, and ignore susceptibility. It has been found that that both very high and high susceptibility areas are along Datou Hill and the foothills of the study area. This finding is verified by field observations. With the investigations conducted in this paper, it can be concluded that the susceptibility maps produced in this paper are reliable and accurate, and useful as a reference for local governments to make decisions regarding whether or not residents living within sinkhole areas should move.

One of the most important environmental issues which Romania faces as member of the European area is land management and natural resources exploitation within protected areas. A good example is the Natura 2000 ROSCI0103 Lunca Buzaului (Buzău and Brăila Counties, Romania). This protected area was established with the purpose of conserving habitats and species characteristic of aquatic and riparian ecosystems, in a region with significant anthropic stress generated by alluvial deposits exploitation, waste storage, agricultural activity, and hydro energy producing potential. The need to put such area in value requires an integrated approach, based on the use of GIS and remote sensing data. In this study, the following resources have been used: Pléiades panchromatic and multispectral images at 0.5 and 2 m spatial resolution, orthophotos with a 2.5 m spatial resolution, a digital terrain model (DTM) based on a 30 m network, topographical plans with 1:5000 and 1:10000 scales, thematic vectors for land using - after Corine Land Cover 2006 data sets. The time difference in the acquirement of images, the exploitation of all the aforementioned data, provides the possibility of having a time scale perspective, between 1970 and 2012. The data have been processed using specific software - ArcGis 10.0 for management of spatially referenced data, ENVI EX for remote sensing data processing and RockWorks 12 for geological and hydrogeological data processing. In the next step, processed remote sensing data, correlated with field collected data has led to the following processes: * Design of the flooding areas, along Buzău River and an environmental impact assessment associated with different scenarios; * Evaluation of actual fluvial erosion processes for the Buzău River system, both under natural state and influenced by the alluvial material extraction activities which are taking place in the area. From geomorphological point of view, the specificity of this habitat is given by the pronounced dynamic processes and, consequently, by the necessity of efficient land management. The results related to the extension of flooding areas at different flow rates, morphological instability, and the presence of erosional risk sections, have been correlated with land use characteristics (from Corine Land Cover) for the entire studied region. Obtained results: GIS data base, flooding and geomorphological risk maps. All these are useful useful for developing effective management plans in order to achieve conservation objectives for species and habitats, for mitigating environmental impact, and for elaborating a geological resources sustainable exploitation strategy.

Η Χάρτα της Ελλάδος (Βιέννη, 1796-97) του Ρήγα Βελεστινλή καταλαμβάνει σημαντικό ρόλο στο σύνολο του εκπαιδευτικού και επαναστατικού έργου του μεγάλου εθνεγέρτη και αποτελεί το κορυφαίο επίτευγμα της λόγιας ελληνικής χαρτογραφίας του 17ου-18ου αι. Κύριο αντικείμενο της διατριβής είναι η περιγραφή, η ανάλυση και ο σχολιασμός της Χάρτας ως ενός έργου χαρτογραφικού, με την ορολογία και τις μεθόδους δηλαδή που χρησιμοποιεί η σύγχρονη επιστήμη της Χαρτογραφίας και με την υποστήριξη ψηφιακών εργαλείων και τεχνικών. Η όλη εργασία αποτελείται από 5 κεφάλαια. Από αυτά το Κεφ. 1 είναι εισαγωγικό στη Χάρτα της Ελλάδος και το ιστορικό πλαίσιο της δημιουργίας της, ενώ καταγράφεται με σύντομη περιγραφή η σχετική βιβλιογραφία, ελληνική και ξένη. Τα Κεφ. 2 έως 4 αποτελούν τον πυρήνα της εργασίας και αναφέρονται στη χαρτογραφική προσέγγιση της Χάρτας. Στο Κεφ. 2, γίνεται η “αναγνώριση–ανάγνωση” της Χάρτας σύμφωνα με τη μεθοδολογία της χαρτογραφικής επιστήμης και γίνεται εκτενής αναφορά στο σημαντικό θέμα της ύπαρξης δύο διαφορετικών εκδόσεων της Χάρτας και παραλλαγών τους. Ακολουθεί στο Κεφ. 3 η περιγραφή της ψηφιοποίησης της Χάρτας, εικονοψηφιδωτά και για πρώτη φορά διανυσματικά, καθώς και η περιγραφή της βάσης δεδομένων GIS που δομείται με βάση τη διανυσματική ψηφιοποίηση. Στο Κεφ. 4 εξετάζονται οι δυνατές εφαρμογές της ψηφιοποίησης και της βάσης δεδομένων. Στο τελευταίο Κεφ. 5, η Χάρτα συγκρίνεται με τον μόλις τρία χρόνια μεταγενέστερο “παρεμφερή” χάρτη του Άνθιμου Γαζή Πίνακα της Ελλάδος (Βιέννη, 1800) και γίνονται διάφορες αναλύσεις, τα αποτελέσματα των οποίων αναδεικνύουν τον Πίνακα ως έναν διαφορετικό χάρτη και όχι επανέκδοση σε σμίκρυνση της Χάρτας, όπως θεωρήθηκε ήδη από τον 19ο αι. Η ψηφιακή χαρτογραφική προσέγγιση της Χάρτας συμπληρώνεται με εφαρμογές αξιοποίησης των τεχνικών και πρακτικών των ψηφιακών τεχνολογιών, όπως αναπτύσσονται τα τελευταία χρόνια για την αντιμετώπιση θεμάτων χαρτογραφικής ανάλυσης των ιστορικών χαρτών. Στις εφαρμογές αυτές, αναδείχτηκε η συμβολή των ψηφιακών τεχνολογιών στην επίλυση προβλημάτων σύνθεσης των φύλλων ή παραμόρφωσής τους λόγω του τρόπου ψηφιοποίησης και στη διερεύνηση ομοιοτήτων και διαφορών με τα προτεινόμενα ακτογραμμικά πρότυπα. Εξάλλου, η ψηφιοποίηση και αρχειοθέτηση της Χάρτας σε διανυσματική μορφή δίνει τη δυνατότητα για γεωχωρική ανάλυση των γεωδεδομένων που δεν είναι δυνατή με την ψηφιοποίηση σε εικονοψηφιδωτή μορφή. Με τη διανυσματική ψηφιοποίηση δομήθηκαν βάσεις δεδομένων που χρησιμοποιούνται για την επιπλέον ανάλυση των γεωχωρικών συσχετισμών στη Χάρτα και για τη δημιουργία μίας σειράς χαρτών που αναδεικνύουν το θεματικό περιεχόμενο της Χάρτας. Με την αξιοποίηση εξάλλου των δυνατοτήτων που προσφέρουν τα ψηφιακά περιβάλλοντα και το διανυσματικό αρχείο της Χάρτας, διευκολύνεται η σύγκρισή της με τον Πίνακα, με ενδεικτικά παραδείγματα για τη μελέτη των ακτογραμμικών προτύπων και του θεματικού της περιεχομένου. Τα χαρτογραφικά αποτελέσματα της εργασίας, με τις δυνατότητες που προσφέρει το ψηφιακό περιβάλλον, εφαρμόζονται στην επαναπροσέγγιση της Χάρτας της Ελλάδος, καθιστώντας την επίκαιρη, όπως αξίζει στο κορυφαίο γεωγραφικό και χαρτογραφικό έργο της προεπαναστατικής περιόδου στην ελληνική διανόηση, αλλά και ως ένα παγκόσμια σημαντικό έργο.

City cores, widely known as central business districts, are the most important part of a city that is also considered as economic center or business administration point. Dhaka, the capital of Bangladesh, is a mega city with ever-increasing population. Its gradual development pattern on the north has induced the growth of many cores. Being a small city with many cores, Dhaka possesses a unique characteristic that allows the functional area of these cores to hold characteristics of their own. This study aimed to find out the characteristic of these cores by identifying the functional area. Different studies mentioned Motijheel, Karwan Bazar, Gulshan–Banani, Mohakhali, and Mirpur as the city cores. The objectives of this study are to delimit the functional area of these cores by kernel density analysis on the basis of land-use concentration and compare the characteristics on the basis of space use, structure height, accessibility, and space rent. An updated GIS database of year 2016 has been used for this study. Kernel density and space index has been used in delimitating and determining the boundaries. Comparison of these cores has brought out their characteristics. These characteristics have showed that each of the cores has their own distinctive natures and properties. Therefore, these cores cannot be administered in a unified way. Considering this, the cores have been delimitated using observation on the basis of their characteristics. Development pattern of these areas needs to be monitored according to the present spatial condition of the city.
