Overview of attributes

The digital database for the Surficial geologic map of The Loop and Druid
Arch quadrangles, Canyonlands National Park, Utah includes three
geospatial datasets as ARC/INFO coverages: cany_poly (geology), cany_point
(sinkholes), and cany_anno (annotation). Geospatial entities in ARC/INFO
coverages have the following software-defined attributes: <cover>.pat
contains AREA, PERIMETER, COVER#, and COVER-ID; <cover>.aat contains
FNODE#, TNODE#, LPOLY#, RPOLY#, LENGTH, COVER#, and COVER-ID. User-defined
attributes are described in detail below.
(1) The coverage cany_poly includes the following feature attribute
tables: (a) a polygon feature attribute table (cany_poly.pat) that
describes the geospatial distribution of geologic units represented in
the Postscript(.eps) and Portable Document Format (.pdf) plotfiles of the
map; (b) an arc feature attribute table (cany_poly.aat) that describes
the contacts and linear features that bound rock-unit polygons.
(2) The coverage cany_point includes a point feature attribute table
(control.pat) that describes the geospatial distribution of sinkholes.
(3) The coverage cany_anno includes two annotation feature attribute
tables: (a)(cany_anno.tatunit) containing unit labels derived from the
coded item PTYPE in cany_poly and (b)(cany_anno.tatstructure) containing
fault separation values. An arc feature attribute table (cany_anno.aat)
contains leaders from the unit annotation to the related polygon.
