Geo-Processing Helper Functions

Helper tools for facilitating basic geo-processing tasks, such as reading/writing Shapefiles, merging polygons or generating terrain contours.


APfun: Base tools for facilitating the creation geo-processing functions in R

Authors: Andrew Plowright

Build Status

This package is intended to provide basic tools for the development of higher level geo-processing functions. For instance, the AProunder function is used to define the extent of tile schemes in the TileManager library, or create summaries of tree stock in ForestTools.
