Description:
Abstract:
This digital geospatial data set consists of digitized
water-table-altitude contours that were manually drawn at an
interval of 20 feet.  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.  It also was used as an input source
for the automated generation of a water-table surface that was in
turn used to generate an unsaturated-thickness surface, also
contoured for use in a 1:50,000-scale map.
Supplemental_Information:
Procedures_Used
Water-level-altitude data from well logs (see "Notes" section)
were manually plotted and contoured onto mylar overlays of 20
paper USGS 7.5-minute topographic series quadrangle maps that
encompass the Denver metropolitan area.  These maps were the Arvada,
Box Elder School, Brighton, Commerce City, Coal Creek, Eastlake,
Englewood, Fitzsimons, Fort Logan, Golden, Highlands Ranch, Indian
Hills, Lafayette, Littleton, Louisville, Mile High Lakes, Morrison,
Parker, Piney Creek, and Sable quadrangles. The contours from these
maps were digitized into 20 corresponding geospatial data sets,
known as coverages in ARC/INFO terminology.  The coverages were
in the polyconic projection specific to each quadrangle: the central
meridian was the longitude of the center of the quadrangle, and
the latitude of the origin was the latitude of the bottom of the
quadrangle.  Registration root mean square errors of 0.008 inches
or less were acceptable for the digitization process.  Drafts of
these coverages were then plotted at a scale of 1:24,000, checked
against the original mylar overlays, and corrected for omissions
and locational errors.  Arc items "CONTOUR" and "DASH" were added
to the arc attribute table of the coverage and manually attributed
in Arcedit, using the original manuscript mylars for references.
The coverages were then projected into a common state plane
projection and edgematched.

The northern and eastern areas of each coverage were edgematched
when necessary.  The northern edge of a coverage was adjusted to
fit the southern edge of a coverage adjacent to the north; the
eastern edge of a coverage was adjusted to fit the western edge
of a coverage adjacent to the east.

The coverages were appended into a single coverage that was then
cleaned with an arc dangle tolerance of 12.192 feet and a fuzzy
tolerance of 1.2192 feet.  The coverage was built with polygon
topology.  The coverage was plotted at 1:50,000, checked, and
corrected.

Arc item "TEXTKEY," was added to the arc attribute table of the
coverage and manually attributed in Arcedit, using hardcopy and
base map overlays for references.  The last two digits of item
"CONTOUR" were redefined in INFO to be item "INDEXKEY."

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.

Revisions
Revision 1.0, August 1996, original data set.

Reviews_Applied
July-August 1994:  Colleague review of 1:50,000-scale maps that
were generated from the original data set.  Manuscript review
included validation of method as outlined in map report and
inspection for positional accuracy.

January-Febuary 1996:  Colleague review of original digital data
set and associated metadata.  Metadata review included verification
of table and column/item identities and definitions, validation of
the reference data sets and citations, verification of consistency
between log file and documented procedures, and validation of
development method as described in the documentation.

March 1996:  Inspection of 1:50,000-scale hardcopy generated from
this data set.

The contours that comprise this data set were digitized by hand
from hand-drawn maps.  The hand-drawn contours were interpolated
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.
However, the wells were not evenly distributed throughout the study
area, nor were their locations field-verified.

The contours that represent the vertical information in this data
set were digitized by hand from hand-drawn maps.  The hand-drawn
contours were interpolated using water-level data from wells that
were not evenly distributed throughout the study area.  Water-level
data were measured in different seasons in different years.

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

Arc attribute "DASH" indicates line symbol type (dash or solid)
intended for use in plotting the illustration.  Dashed contour
locations are less accurate.

Arc attribute "TEXTKEY" indicates how contour values are drawn in
a plotting routine:
B = no text.
L = text above line lc.
U = text below uc.
P = text using point2 blank.
S = text using LINE blank.
G = text using point2 blank gray mask.

Arc attribute "INDEXKEY" delineates between 100-foot index contours
and non-index contours in a plotting routine.  Its values are the
character equivalent of the last two digits in item "CONTOUR."
