主题: [?? Probable Spam] Re: [gdal-dev] which function can fetch some
supplementary(but necessary) information of geometry from s-57 file?
Randy,
OGRPoint is a geometry, which is stored as a part of a feature in a
layer of the dataset. Any other information about the geometry is
usually acquired from the OGRLayer and other fields in the OGRFeature.
Hope this helps.
