Hi, I"m totally new to GDAL, sorry if this is a obvious thing for you.
Trying to filter features in the area with following code snippet. However poLayer->GetNextFeature() always returns null on my windows 8. OGRPolygon* polygon = new OGRPolygon(); > OGRLinearRing* ring = new OGRLinearRing(); > ring->addPoint(51.089028, 13.617821); > ring->addPoint(51.089675, 13.807336); > ring->addPoint(51.025585, 13.807679); > ring->addPoint(51.024937, 13.616105); > polygon->addRing(ring); > poLayer->SetSpatialFilter(polygon); The full code is http://pastebin.com/eWUeVsTG I suspected geos dll is not loaded, but it's loaded according to following output. http://pastebin.com/7r1gUdQq Best Regards Tunca Tunc
