Hi Norman,
My comments :
- I'm wondering if we must really derive a new class GDALAsyncDataset from
GDALDataset. We could as well add the new methods as new virtual methods in
GDALDataset, and make a NULL-implementation of them in GDALDataset. The point
of this remark is for the C API associat

Craig,
BTW, you don't have to convert OGRGeometry (you play with it when
reading Shapefile using OGR) to geos::geom::Geometry.
You can union OGRGeometry using OGRGeome

A topological union results in existing geometry being split into multiple

You need to make all GDAL DLL binaries and all GDAL DLL dependencies

"This application has failed to start because gdal15d-vc8 was not found.
Re-installing the application may fix the problem"

In your project properties in vs under the "Link" tab you need to add the path
