Abstract:
The Geographic Foundation Class (GFC) library is a set of C++ classes defining
basic geographic data types, including points, lines, rectangles, circles,
polylines, rings, complex polygons, rasters, and other atomic data types such
as integer, real, varchar. GFC also features abstractions of timestamps and
time series which are useful in capturing the dynamics of spatiotemporal data.
The R-tree spatial indexing is supported through the GRtree and related
classes. Several commonly used map projections are also provided in this
library. A number of utility classes such as GXMLProcessor (for parsing XML
files which are well-suited for transfering spatial meta data) and ESRI
Shapefile reader are very useful for writing GIS applications.
