The Brazilian Geodesign platform was proposed based on extensive experience in Geodesign workshops, aiming to adapt the method to the country’s cultural specificities, with a commitment to support the construction of opinions in planning, in the process of transformative-learning planning. To test the scalability of the method, a study was developed in 13 metropolitan regions of the country, with the involvement of universities, distributed from north to south, in different biomes and urbanization conditions. The same method was proposed for everyone, starting from the same collection of 40 thematic maps to support discussions about alternative futures in land use. Participants used the GISColab platform and went through the same stages of analysis, proposition, and negotiation of ideas. As a result, there was an improvement in the projects developed between the first and the last day of work, with the expansion of compliance with the goals of sustainable development (SDG) and areas for carbon credit. It was possible to observe that, although they used the same framework proposed, each group adapted the method to their local reality, proving the scalability of the process and the necessary flexibility for employment in different realities, ensuring a defensible and reproducible criterion. As recommendations, it would be interesting to apply the same study of multiple simultaneous cases in another country, to analyze the scalability and flexibility to local changes, as it happened in the experiment. This would be entirely possible, as the platform is based on worldwide OGC standards (Open Geospatial Consortium) and would have full interoperability in use.

This paper aims to present a description of the DataGEO project, São Paulo's environmental SDI (Spatial Data Infrastructure), discussing the guidelines used to develop the design and implementation in São Paulo's environmental systems. The text includes the issues around the NSDI's (National Spatial Data Infrastructure) guidelines and the choices made throughout the project, influenced by the specifcs of a thematic environmental SDI and the processes observed in the functioning of SMA-SP (Environmental Secretary, State of São Paulo). Thus, DataGEO expands the SDI's use presenting a platform that may be used not only as a solution for the sharing of spatial data with the public, but also as a proposed solution to attend corporate GIS within large organizations. The paper presents the implementation process and the technological challenges, in addition to discussing new ways of accessing geospatial information based on WebGIS, in which the interoperability and sharing of data helps and supports spatial planning. The authors point to the importance of how a proposition for a platform allowing the integration of information coming from multiple sources through institutional agreements may improve access, usage, sharing and understanding data for group decisions.

The users of geoinformation have been given the opportunity to work with impressive amount of data with some good quality, but it demands knowledge to handle complex and robust collection of information. At the same time the demand for quick answers and analysis requires dynamic cartography capable of execute processes with agility for immediate update of outputs. Together with the improvement of the data quality and the need of fast information production the legal issues is also developed, progressing from the frst steps of the Spatial Data Infrastructure to a services access, via internet, which change data into information, favoring the knowledge production. It is for this scenario that the paper presents as objective to propose a methodology based on database and not only on Geographic Information Systems. It represents contribution as critical reflections and introduction of a methodology for handling high resolution information extracted from orthophotos and altimetry from LiDAR data. It presents the case study of the modeling to assess vegetation and buildings´ volumes in Pampulha region, in the city of Belo Horizonte, Minas Gerais State. The focus is to demonstrate to users of desktop applications based on GIS software, that nowadays are the majority among users of geoinformation technologies, that it is possible to change to the construction of spatial analyzes using the logic of database, in applications of free access, and with signifcant gains in the handling of large amounts of data and the need to apply routines. In this sense, it is an interface between the era of desktop information technology represented by large commercial software and the era of ETL and database logics. The use of spatial geodatabase logics and ETL tools (extract, transform and load) are proposed and tested to improve the performance in terms of time, technical team demand and information security. It numerically proves the performance improvement and contextualizes the process regarding the state-of-art of geoinformation technologies.

This paper argues that the opportunities offered by currently available collaborative Planning Support Systems (PSS) are useful not only for applying a systems approach and coordinating actors in the planning process, but also for tracking the evolution of design alternatives toward a final plan. The availability of process log-data in the latest PSS opens new paths for understanding (geo)design dynamics. With the aim of taking full advantage of this new data source, a novel Geodesign Process Analytics is described in detail from log-data extraction and pre-processing methods and tools to the development of the set of spatial, performance, temporal and design evolution indicators. The study also demonstrates how the proposed measures are appropriate for display in a dynamic dashboard, making available a real-time process analysis tool to the team coordinators, thus supporting their leading role in facilitating the geodesign process. The research assumptions were tested using the Geodesignhub PSS and data from a geodesign study developed within the International Geodesign Collaboration.
