6). Fig. 6 Result of the SPARQL request 36 3 Implementation in R Map Data Geo data, especially national, regional or administrative borders, are frequently saved in so-called shapefiles. This is a very old data format in which map information and associated attributes are saved in a series of files with the same name, but different file extensions. shx The shp file contains the actual geometrical data. These are either points or lines or areas in the shape of polygons. The prj file only contains a so-called projection set, a string with information stating how the originally three-dimensional data are twodimensionally represented in the shp file.
