Hello, I have some map in ShapeFile and I am using OGR to display it. I folow the example od OGR website: OGR C++ API Read/Write Tutorial<http://gdal.org/ogr/ogr_apitut.html> (http://gdal.org/ogr/ogr_apitut.html). Unfortunately that way is very slow. I have map of whole country(only roads) and even when I try to display onlu one big city and I set spatial filter it takes very much times. Could you tell me if gdal/ogr has oportunity to read big files in faster way?
Regards, Paweł
