Description
I have a BSB dataset containing 100+ GCPs. The GCPs generate a very poor fit to a 2nd order polynomial (also fail to generate a valid geotransform in GDALGCPsToGeoTransform). As the result, computed extent in GCS based the GCPs is out of place. The same dataset looks fine in a BSB viewer from maptech.
I placed the test dataset, 530_1.kap at ftp://GDAL@ftp.esri.com. Could you take a look? Maybe the GCPs are read wrong or there is another source of georeferencing info in the file.
