Hi Frank, Thanks for your reply! I know what you mean now, NAME_RCID can tell the difference between Feature records' RCID and Spatial Records', and it is easily to know the NAME_RCNM subfield is from Spatial Record from its prefix-"NAME".

Randy, I always called this field NAME_RCNM so it isn't about what edition it is from. I believe it is named this because it is the RCNM extracted from the NAME field of the feature (FSPT). I presume it is used to lookup the RCNM and RCID in the set of spatial records when composing the geometry for the feature. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
