Hi!
I have this very simple problem which I don't understand. I am loading a shape
file (multipolygon) and copying the geometry into a new structure:
OSGeo.OGR.Geometry geometries = new
OSGeo.OGR.Geometry(OSGeo.OGR.wkbGeometryType.wkbMultiPolygon);
OSGeo.OGR.DataSource dataSource = OSGeo.OGR.Ogr.Open(filename, 0);
OSGeo.OGR.Layer layer = dataSource.GetLayerByIndex(0);
OSGeo.OGR.Feature currentFeature = null;
layer.ResetReading();
while ((currentFeature = layer.GetNextFeature()) != null)
{
string wkt = string.Empty;
currentFeature.GetGeometryRef().ExportToWkt(out wkt); -->
MULTIPOLYGON (((476587.2 6100012.8, .... ,533324.8 6190163.2)))
geometries.AddGeometry(currentFeature.GetGeometryRef());
string wkt2 = string.Empty;
geometries.ExportToWkt(out wkt2); --> MULTIPOLYGON EMPTY
}
dataSource.Dispose();
Am I doing something completely wrong here?
I just want all of the geometry in the input file put into the variable
geometries for later use.
The input data is a rather large data set and before I try to strip it down, I
just want to know if my approach is wrong or if I can expect this to be working.
GDAL/OGR version: 1.9.2, C# bindings from Tamas daily builds.
Regards Casper
