In 2004 van Kreveld and Speckmann presented the first algorithms for the automated construction of rectangular cartograms. The first step for these algorithms is to construct a partition of a large rectangle the map into a set of smaller rectangles that represent the regions of the administrative subdivision to be depicted ("countries") as well as (parts of) adjacent oceans, large lakes, or nei...

www.esri.com The Worldmapper project has successfully produced a series of maps to visualize data concerning a range of issues facing the modern world based on the idea of density-equalizing maps. With this approach, ArcGIS 9.3 plays a crucial role as an interface to convert suitable raster datasets and produce updated cartograms. The data is converted using ArcMap’s ArcToolbox, while the carto...

Cartograms have long been used to highlight the uneven distribution of a phenomenon over given area. On these maps, size spatial units is proportional their weight (the number inhabitants, amount CO2 emitted, etc.). Over past twenty or so years, benefits adding movement this type map–mainly assess changes time and space–have discussed. Several methods suggested for constructing animated cartogr...

Abstract. A rectangular cartogram is a type of map where every region is a rectangle. The size of the rectangles is chosen such that their areas represent a geographic variable such as population or GDP. In recent years several algorithms for the automated construction of rectangular cartograms have been proposed, some of which are based on rectangular duals of the dual graph of the input map. ...

BACKGROUND World maps can provide an instant visual overview of the distribution of diseases and deaths. RESULTS There is a particular geography to each type of death: in some places many thousands of deaths are caused by a particular condition, whilst other equally populous areas have few to no deaths from the same cause. CONCLUSION Physicians and other health professionals often specialis...

The notion of a cartogram is reviewed. Then, based on a presentation from the 1960’s, a direct and simple introduction is given to the design of a computer algorithm for the construction of contiguous value-by-area cartograms. As an example a table of latitude/longitude to rectangular plane coordinates is included for a cartogram of the United States, along with Tissot’s measures for this map p...

As a simple, discontinuous, surface deformation statistical map, Dorling cartograms are effective means with which to characterize the geographic distribution of event data attributes. According existing research, behavioral differences exist in visual cognition individuals different cognitive field styles spatial task switching layers two-dimensional electronic map. However, there few studies ...
