Tools for reading and handling spatial objects
Set of tools for manipulating and reading geographic data,
in particular ESRI shapefiles; C code used from shapelib. It
includes binary access to GSHHS shoreline files. The package
also provides interface wrappers for exchanging spatial objects
with packages such as PBSmapping, spatstat, maps, RArcInfo,
Stata tmap, WinBUGS, Mondrian, and others.
