Hi,I have tested speed of random access to PostGIS features with simple testing application. // about 1e4 points poLayer = poDS->GetLayerByName("bridges"); nfeatures = poLayer->GetFeatureCount(); for (int fid = 1; fid< nfeatures; fid++) poFeature = poLayer->GetFeature(fid);
Martin, I agree with Even's comments about the speed. I would just add that you cannot generally assume that features id's are contiguous as is done above. Also, you are missing feature "0" due to the bounds of your for loop.
