GEO2XY: Stata module to convert latitude and longitude to xy using map projections

Statistical Software Components from Boston College Department of Economics

Abstract: geo2xy converts geographic latitude and longitude to cartesian coordinates (x,y) using map projection transformations. The default projection is a Web Mercator, which is the same used by most web mapping applications (Google Maps, Bing Maps, etc.). As an option, -geo2xy- can generate Tissot's indicatrices (grid of circles) which, when overlaid on a map of the projected coordinates, help visualize the distortions of the chosen projection. With projected coordinates, high quality maps can be produced using standard Stata graph commands or with user-written commands like -spmap-.
