The DEF lines specify many attributes for each GDMS record. All features derived from these records have all of these user-defined attributes. The only exceptions are the coordinate point and flag attributes. These attributes are used to construct the geometry of the feature and are not kept as attributes.
Refer to DEF for a listing of GDMS attributes.
Lines
gdms_type: gdms_line
GDMS line features represent linear features in 2D. Line features do not have any specific attributes.
gdms_type: gdms_text_line
GDMS line features represent linear features in 2D. Line features do not have any specific attributes.
Points
gdms_type: gdms_point
GDMS point features represent point features in 2D. Point features do not have any specific attributes.
