Description:
Abstract:
This digital geospatial data set consists of bedrock-surface-altitude
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
with the ARC/INFO GRID function, MERGE, and projected into an
appropriate coordinate system with the command, PROJECT.  The
resulting grid was then smoothed using an averaging filter with a
radius of 9 grid cells (180 meters):

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

Line data sets (coverages, in ARC/INFO terminology) of unconsolidated-
sediment thickness contours and bedrock-outcrop outlines (documented
separately) were converted to a grid with the same cell size as
the DEM-derived data (approximate 30-meter spacing between data
points):

The unconsolidated-sediment-thickness grid was subtracted from
the land-surface-altitude grid to produce a grid of bedrock-
surface altitude.  The software generated the contour coverage at
an interval of 20 feet using the bedrock-surface-altitude grid.
This coverage was clipped to fit the study area boundary.

Arc: latticecontour brgrd96b brcnt96b 20 0 # 20 #
Arc: clip brcnt96b /gis/users/robson/finals/studyarea brcnt96b1 line .001

The jagged appearance of the contours was addressed by smoothing
the contours in an Arcedit 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 set to 30 meters
before splining the arcs again.

The coverage was built with line topology.  Manual editing corrected
contours that were not correctly interpolated, as determined by
consultation with the projects author; For example, contours that
formed closed polygons with perimeters less than 200 meters, as
well as contours that overlapped large lakes, were removed or
altered.  Arc items "TEXTKEY," "CNT_INT," and "DEPRESSION" were
added to the arc attribute table of the coverage.

Further editing delineated the different display characteristics
of the arcs in a plotting routine.  The Arc items "TEXTKEY" and
"DEPRESSION" were attributed in this editing session.  Hardcopy
and base map overlays were used for reference.

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

The contours that comprise two of the input data sets (overburden
and all_obsup) were digitized by hand at a scale of 1:24,000 from
hand-drawn maps.  The hand-drawn contours for overburden 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.

Overview_Description:
Entity_and_Attribute_Overview:
Arc attribute "CONTOUR" is the bedrock surface altitude in feet
above sea level.

Arc attribute "CNT_INT" is the integer equivalent of item "CONTOUR"
and was used to create item "CNT_CHR."

Arc attribute "CNT_CHR" is the character equivalent of item
"CNT_INT," used for selecting 100-foot index contours (that is,
CNT_INT containing "00").

Arc attribute "DEPRESSION" indicates whether or not a line delineates
a depression feature.  Lines that delineate depressions are coded
as "Y"; non-depression features are coded as "N."

Arc attribute "TEXTKEY" indicates how contour values are drawn in
a plotting routine:
B = no text drawn.
S = text drawn using splined blank white mask.
G = text drawn using splined blank gray mask.
Q = special case, changed textspacing and textmask rectangle
size.
