An approach to automate block cartogram creation
by Jeff Blossom
Presented at the North American Cartographic Information Society annual meeting.
October 21, 2017, Colorado Springs.
Cartograms that show a statistic in the form of equal sized blocks allow the map reader to quickly compare quantities across an area. However, at the time of this project, there existed no tool or algorithm that automatically converts a GIS shapefile into a block cartogram. This talk will detail an approach that produced a block cartogram for a Texas County shapefile using data manipulation in Excel and the Cartography Toolbox in ArcMap.
