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:

TABLE srp94g13
Purpose:      contains the attributes of points representing orientation
                   measurements
Columns:
planar_id      A unique identification for each planar measurement
planar_typ    The type of planar feature. Examples: bedding, cleavage
modifier        Description of the feature type. Examples: overturned, irregular
strike           Strike (according to the Right-Hand Rule)
dip               Dip
location        Distance/direction from the station if measured between stations
                   or away from the station
trend            Trend of linear feature (value of 999 if no measurement available)
plunge          Plunge of linear feature (value of 999 if no measurement
                   available)
linear_typ      The type of linear feature. Examples: ripple crests, fold axis
comment      Notes relating to measurement
station_id      A unique identification of the outcrop where the measurements
                    were taken
disp_ang       Achieves Right-Hand Rule orientation of symbols in ArcView.
                    Derived using the formula (270-strike)

Some formations are locally represented by lines rather than polygons, where their thicknesses are less than the 1:50 000 map resolution.
