PROCESS DESCRIPTION: 
Geological features were digitized in MicroStation/J, exported as DXF and imported to ArcInfo 8.2. User-defined attributes were added to complete the tables as described below.
 
ARCINFO GENERATED COLUMNS:
AREA            area of polygon
PERIMETER  perimeter of polygon
FNODE#        Internal sequence number of the from-node
TNODE#        Internal sequence number of the to-node
LPOLY#        Internal sequence number of the left polygon
RPOLY#        Internal sequence number of the right polygon
LENGTH        Length in coverage units
COVER1#      Internal sequence number (i.e., the record number) of the arc in
                     the ARC file
COVER-ID     User-assigned feature ID


USER-DEFINED ATTRIBUTES - POINT FEATURES:
