To read a specific geo key stored in a file, use ReadGeoKey(String,Int32,Int32) and to enumerate all the GeoKeys stored in a file use EnumGeoKeys(String,Int32).
This method will throw an exception if the file format does not support GeoKeys. To determine whether a file format supports GeoKeys, use GeoKeysSupported. You can also automatically load all the GeoKeys stored in a file during a load operation by setting the CodecsLoadOptions.GeoKeys property to true. The GeoKeys data will be stored in the resulting image RasterImage.GeoKeys collection.
To load all the GeoKeys stored in a disk file, use ReadGeoKeys(String,Int32).
