METADATA - E00 FILES 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
srp94g5 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) nts_map National Topographic System designator. Example: 94G/5

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