Get ID's of the shape items. For polygons and lines, the ID attribute is used. For points, the coordinates are used.


Set of tools for reading and processing spatial data. The aim is to supply the workflow to create thematic maps. This package also facilitates 'tmap', the package for visualizing thematic maps.
