The earth mass cartogram is a graphical representation of earthworks for calculating the volume of these works using the square method. The method of squares became widespread in the era of the absence of programmable computational tools and is a deliberate discretization to enable the calculation to be performed manually. GOST 21.508-93 SPDS allows the implementation of the plan of earth masses using other methods. In this case, the content and form ofthe plan should be determined by the method used and the conditions of the work

A generic rectangulation is a partition of a rectangle into finitely many interior-disjoint rectangles, such that no four rectangles meet in a point. In this work we present a versatile algorithmic framework for exhaustively generating a large variety of different classes of generic rectangulations. Our algorithms work under very mild assumptions, and apply to a large number of rectangulation classes known from the literature, such as generic rectangulations, diagonal rectangulations, 1-sided/area-universal, block-aligned rectangulations, and their guillotine variants. They also apply to classes of rectangulations that are characterized by avoiding certain patterns, and in this work we initiate a systematic investigation of pattern avoidance in rectangulations. Our generation algorithms are efficient, in some cases even loopless or constant amortized time, i.e., each new rectangulation is generated in constant time in the worst case or on average, respectively. Moreover, the Gray codes we obtain are cyclic, and sometimes provably optimal, in the sense that they correspond to a Hamilton cycle on the skeleton of an underlying polytope. These results are obtained by encoding rectangulations as permutations, and by applying our recently developed permutation language framework.

This thesis contributes to improvements in effectively communicating population related cancer distributions and the associated burden of cancer on Australian communities. This thesis presents a new algorithm for creating an alternative map displays of tessellating hexagons. Alternative map displays can emphasise statistics in countries that contain densely populated cities. It is accompanied by a software implementation that automates the choice of one hexagon to represent each geographic unit, ensuring the statistic for each is equitably presented. The case study comparing a traditional choropleth map to the alternative hexagon tile map contributes to a growing field of visual inference studies.

This paper evaluates the potential of using cartograms for visualizing and interpreting forecasts of weather-driven natural hazards in the context of global weather forecasting and early warning systems. The use of cartograms is intended to supplement traditional cartographic representations of the hazards in order to highlight the severity of an upcoming event. Cartogrammetric transformations are applied to forecasts of floods, heatwaves, windstorms and snowstorms taken from the European Centre for Medium-range Weather Forecasts (ECMWF) forecast archive. Key cartogram design principles in standard weather forecast visualization are tested. Optimal cartogram transformation is found to be dependent on geographical features (such as coastlines) and forecast features (such as snowstorm intensity). For highly spatially autocorrelated weather variables used in analysing several upcoming natural hazards such as 2m temperature anomaly, the visualization of the distortion provides a promising addition to standard forecast visualizations for highlighting upcoming weather-driven natural hazards.

In this paper, we are concerned with the problem of creating flattening maps of simply connected open surfaces in ℝ3Using a natural principle of density diffusion in physics, we propose an effective algorithm for computing density-equalizing maps with any prescribed density distribution. By varying the initial density distribution, a large variety of flattening maps with different properties can be achieved. For instance, area-preserving parameterizations of simply connected open surfaces can be easily computed. Experimental results are presented to demonstrate the effectiveness of our proposed method. Applications to data visualization and surface remeshing are explored.

A table cartogram of a two dimensional m×n table A of non-negative weights in a rectangle R, whose area equals the sum of the weights, is a partition of R into convex quadrilateral faces corresponding to the cells of A such that each face has the same adjacency as its corresponding cell and has area equal to the cell's weight. Such a partition acts as a natural way to visualize table data arising in various fields of research. In this paper, we give a O(mn)-time algorithm to find a table cartogram in a rectangle. We then generalize our algorithm to obtain table cartograms inside arbitrary convex quadrangles, circles, and finally, on the surface of cylinders and spheres.

A new method of quantitative predictive risk assessment of exogenous geological processes (EGP), which is based on the studies of spaciotemporal prediction of their development is proposed. The algorithm is presented, which includes the main stages of calculation: determining the set of EGP for risk calculation; analyzing spaciotemporal development of EGP considering initiating factors; creating predictive spaciotemporal development models of EGP; selecting the spatial and analytical-descriptive hazard and risk assessment system; constructing predictive risk assessment maps according to the type of EPG; summarizing the estimates of spatial and protective systems, and building the integrated risk map for all types of EPG.The calculation of the given landslide risk is based on the calculation of average spaciotemporal landslide probability, partial and total landslide area for the analyzed period, the maximum area of damage, population density, the coefficient that takes into account the presence of protective systems in the area. Landslide risks for the year of maximum landslide activity are calculated. The cartogram of landslide risk estimates for administrative-territorial units (rural and city councils) on the example of the Ivano-Frankivsk region is built., Предложенный новый метод количественной эколого-геологической оценки рисков оползневой опасности.

The diffusion-based algorithm to produce density-equalizing maps interprets diffusion as an advection process. This algorithm uses the dynamics of a flow that is defined by an initial value problem that turns out to be very singular at the initial time. The singularities appear when the initial density has line or angle discontinuities, which is always the case, for example, in area cartogram maps. This singular initial value problem is analyzed mathematically in this article and the conclusion is that despite these singularities, it has a unique solution. This justifies the extensive numerical use of this algorithm in the recent years. The techniques presented in this article use both partial and ordinary differential equations estimates., Peer Reviewed, Postprint (published version)

In 1972 Lou Skoda and J.C. Robertson published an isodemographic map (a cartogram) of Canada that represented a population-oriented rendering of the 1966 Canadian census divisions. The map was developed with a physical analog model that kept all of Canada together in a contiguous mass while preserving recognizable divisions and province outlines.
