In the next example, called ch09_shp
, we implement a method to import binary layers to our maps. Shapefile is an old specification to store vector data; however, it is still a very common and popular exchange format. It stores the geometry in a binary file, which has an shp
MIME type. There are usually at least three more files along with the geometry. The shx
file stores the shape indexes of the geometries in a binary format, providing an internal spatial indexing for faster lookups. The prj
file is an ASCII file containing the projection string of the layer, while the dbf
file is a dBASE database file containing attribute data. For this example to work, we will need at least the shp
and dbf
files of a shapefile.
