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.
APcontours - Added ability to control maximum number of segments per contour line. Ensured that output object's 'levels' attribute was numeric instead of a string. APpolygonize - Added 'outFile' argument AProunder - Allow input of 'Extent' objects
Added following functions to facilitate reading and writing of Shapefiles
APSHPread - Read a Shapefile APSHPsave - Save a Shapefile APKML2SHP - Convert a KML to a Shapefile APSHPfiles - List all files associated with a Shapefile (ex.: yourfile.shp, yourfile.xml, yourfile.prj, etc.) APSHPdel - Delete Shapefile and all associated files
In addition, the 'APpolyMerge' function was added, which facilitates merging multiple polygonal Spatial objects.
Added following functions:
APcontours - Generates elevation contours at 'tidy' height values APprecise - Prints a number with all decimal values (i.e. no rounding) APopen - Opens a folder in Windows Explorer APpolygonize - Converts a raster into polygons using a GDAL utility
