Description:
Abstract:
This digital geospatial data set consists of saturated-thickness
contours that were generated with a Geographic Information System
(GIS).  The U.S. Geological Survey developed this data set as part
of a project that is presented in the report, Geohydrology of the
shallow aquifers in the Denver metropolitan area, Colorado (Robson,
1996).
Purpose:
This data set was created by the U.S. Geological Survey (USGS) in
the development of USGS Hydrologic Investigations Atlas HA-736
(Robson, 1996).  This data set was used in the creation of a
1:50,000-scale contour map.

Procedures_Used
Using ARC/INFO software, USGS 7.5-minute Digital Elevation Models
(DEMs) that encompass the study area were converted to raster surface
formats (grids, in ARC/INFO terminology) with the command DEMLATTICE.
They were mosaicked into a single continuous surface using the
ARC/INFO GRID function, MERGE, and projected into an appropriate
coordinate system using the ARC/INFO command, PROJECT.  The grid
then was smoothed using an averaging filter with a radius of 9 grid
cells (180 meters):

Grid: lsdcir9 = focalmean (all_lsd7spc, circle, 9, data)

Contour data sets (coverages, in ARC/INFO terminology) of water-
level altitude and unconsolidated-sediment thickness (documented
separately) were converted to grids with the same cell size as
that of the DEM-derived grid (approximately 30-meter spacing
between points).

Arc: createtin wttin3 30 30
Createtin: cover watertable2 line contour 1
Createtin: cover wtpts point contour 1
Createtin: end
Arc: tinlattice wttin3 wtgrd3 quintic
Arc: createtin obtin2 # 30
Createtin: cover all_obsup line contour 1
Createtin: cover overburden line contour 1
Createtin: cover outcrop4 poly 5
Createtin: end
Arc: tinlattice obtin2 obgrd2 quintic

The unconsolidated-sediment-thickness grid was subtracted from the
land-surface-altitude grid to produce a bedrock-surface-altitude
grid.

Grid: bdrkgrd = lsdcir9 - obgrd2

A saturated-thickness grid resulted from the subtraction of the
bedrock-altitude grid from the water-level-altitude grid.  Before
the contouring process, the saturated-thickness grid was processed
to remove values less than or equal to -10 feet.

Grid: satgrd5 = wtgrd3 - bdrkgrd
Grid: satgrd5a = select (satgrd5, value ge -10)

A saturated-thickness contour coverage was generated by the
software at an interval of 20 feet.

Arc: latticecontour satgrd5a satcnt5a 20 0 contour 20

Manual editing corrected contours that were not appropriately
interpolated as determined by consultation with the projects
author.  The coverage was built with line topology.  The coverage
then was clipped with a coverage of an outline that delimited the
extent of 20-foot-interval water-level contours.  Contour "islands"
with a perimeter length of 1,000 meters or less were removed from
the coverage in ARCEDIT.

The jagged appearance of the contours was addressed by smoothing
the contours in an editing session.  Arc vertex grain tolerances
(the minimum allowable distance between vertices in a line) were
set to 90 meters, all the arcs were generalized with the Arcedit
command, SPLINE, and the grain tolerances were reset to 30 meters
before splining the arcs again.

After initial colleague reviews, the coverage was processed to
support polygon topology.  First, the clipping coverage that was
used to produce the line coverage was added to the line coverage
itself in an ARCEDIT session.  The resultant coverage was further
edited to connect all contours to the clipping outline.  The
coverage then was built with polygon topology.  Contours with
thickness values equal to zero were removed from the coverage, and
polygon topology was recreated.  Polygon item "RANGE" was added
to the polygon attribute table of the coverage.  After labels were
created for the polygon coverage, the coverage was attributed for
"RANGE" values in ARCEDIT.

The final coverage is intended to be used as one thematic layer in
maps to be published at a scale of 1:50,000.

The DEM-derived input data set was smoothed with a circular filter
of a 9-cell-length (180-meter) radius.  After the data set was
smoothed, it matched more closely the apparent resolution of the
water-table data set.  The final saturated-thickness contour data
set would have been too convolute (implying more detail than was
supportable by the water table data set) if it had been produced
using an unfiltered DEM-derived data set.

The contours that comprise three of the input data sets (overburden,
all_obsup, and watertable2) were digitized by hand at a scale of
1:24,000 from hand-drawn maps.  The hand-drawn contours for
overburden and watertable2 were interpolated at 20-foot intervals
using data from wells whose locations were reported in Public Land
Survey System coordinates.  The well locations are theoretically
accurate to the nearest quarter-quarter-quarter-quarter section,
but they were not field-checked for accuracy.  Also, the well
locations were not evenly distributed throughout the study area.
The limited number of supplemental hand-drawn contours that comprise
all_obsup were interpolated at 10-foot intervals and were intended
to enhance the surface interpolation in areas where the CREATETIN
session failed to accurately represent the unconsolidated-sediment-
thickness surface.

The bedrock-outcrop outlines that comprise another input data set
also were digitized by hand at a scale of 1:24,000 from hand-drawn
maps.  The hand-drawn outlines were not field-checked for accuracy.

Overview_Description:
Entity_and_Attribute_Overview:
Arc attribute "CONTOUR" is the thickness of the saturated zone in
feet.

Polygon attribute "RANGE" is a key for plotting the saturated-
thickness range of the polygon feature.  The actual range is equal
to the range value in feet, plus or minus 10 feet.
