[Gdal-dev] GDAL Capabilities

[Patrick Rouse]

Hi,

I am looking for an opensource solution to a simple gis/topology problem.  I am
an Arcinfo guy, so I know how to do this within the realm of aml and visual
basic, but I have been tasked with creating a simple opensource (c++), portable
program to generate a dynamic polygon based on lat/lon points input by the user
and determine which polygons on a shapefile (us counties) fall within or
intersect this dynamic polygon.  A simple check to see if the county polygons in
the shapefile fall within or intersect  the dynamic polygon.  Browsing the
documentation it seems that this library is capable of this.  I am not much of a
c++ programmer, but I will be assisting a real c++ programmer in this project
and I am looking for possible solutions to present to him.  Let me know if this
library can handle this operation and if possible links to any sample code used
for opening shapefiles and performing topological tests.

thanks very much
