Thematic mapping with free software PhilCarto

Thematic mapping with free software PhilCarto

Kazimierz Zaniewski, University of Wisconsin-Oshkosh

In addition to ArcGIS and other major mapping software packages, there are several less known but fairly powerful programs designed for generating high quality thematic maps. One of them is PhilCarto, a free software developed and maintained by a French geographer at the University of Bordeaux. This mapping software is capable of producing all major types of thematic maps, including choropleth, proportional symbol, bar graph, pie chart, dot density, flow, 3-D surface, and gravity maps. It also has a set of statistical tools for mapping the results of exploratory data analysis, including ternary diagrams and regression, factor, and cluster analyses. The PhilCarto cartographic output is of very high quality and can be exported to illustration software for final touches. A companion to PhilCarto is PhilDigit, a boundary creation (digitization) and manipulation software. It can import and export ArcGIS (shapefiles) and MapInfo (mif/mid) boundary files.
