## classes and methods for spatial data

A package that provides classes and methods for spatial
data. The classes document where the spatial location
information resides, for 2D or 3D data. Utility functions are
provided, e.g. for plotting data as maps, spatial selection, as
well as methods for retrieving coordinates, for subsetting,
print, summary, etc.
