“Re-Mapping the World’s Population” – Presentation at the ESRI International User Conference in San Diego, 13-17 July 2009
The Worldmapper project has successfully produced a series of maps to visualize data, concerning a range of issues facing the modern world, based upon the idea of density-equalising maps. The Cartogram Geoprocessing Tool incorporating this density-equalising method has also recently been made available for ArcGIS. This presentation introduces and evaluates further new mapping approaches that move depictions beyond their simple descriptive form. It gives an insight into these new developments, focusing on sub-national level data which has until now been neglected. The world population cartogram demonstrates the first attempt to include sub-national density data. Within this approach, ArcGIS 9.3 plays a crucial role as an interface to convert suitable raster datasets and to produce updated cartograms. The data is converted using ArcMap’s Toolbox, while the Cartograms, due to their large size were, calculated in a Unix environment. The final visualization has been conducted in ArcMap.
