R. 1997 1.0 map Open-File Report 96-445 Reston, VA U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?ofr96-445_wlelev This data set consists of digital water-level elevation contours for the alluvial and terrace deposits along the Cimarron River in northwestern Oklahoma during 1985-86. Ground water in 1,305 square miles of Quaternary-age alluvial and terrace deposits along the the Cimarron River from Freedom to Guthrie is an important source of water for irrigation, industrial, municipal, stock, and domestic supplies. Alluvial and terrace deposits are composed of interfingering lenses of clay, sandy clay, and cross-bedded poorly sorted sand and gravel. The aquifer is composed of hydraulically connected alluvial and terrace deposits that unconformably overlie the Permian-age Formations. Water-level elevations measured in 1985 and 1986 ranged from 1,650 feet to 950 feet above sea level. Regional ground-water flow is generally southeast to southwest towards the Cimarron River, except where the flow direction is affected by perennial tributaries. The water-level elevation contours were digitized from a mylar map at a scale of 1:250,000. The maps were published at a scale of 1:900,000. This data set was created for a project to develop data sets to support ground-water vulnerability analysis. The objective was to create and document a digital geospatial data set from a published report or map, or existing digital geospatial data set that could be used in ground-water vulnerability analysis. Introduction -- This data set consists of digital water-level elevation contours for the alluvial and terrace deposits along the Cimarron River in northwestern Oklahoma during 1985-86. Ground water in 1,305 square miles of Quaternary-age alluvial and terrace deposits along the the Cimarron River from Freedom to Guthrie is an important source of water for irrigation, industrial, municipal, stock, and domestic supplies. Alluvial and terrace deposits are composed of interfingering lenses of clay, sandy clay, and cross-bedded poorly sorted sand and gravel. The aquifer is composed of hydraulically connected alluvial and terrace deposits that unconformably overlie the Permian-age Formations (Adams and Bergman, 1996). In this report, elevation refers to distance above sea level and sea level refers to the National Geodetic Vertical Datum of 1929 (NGVD29)--a geodetic datum derived from a general adjustment of the first-order level nets of both the United States and Canada, formerly called Sea Level Datum of 1929. Water-level elevations measured in 1985 and 1986 ranged from 1,650 feet to 950 feet above sea level. Regional ground-water flow is generally southeast to southwest towards the Cimarron River, except where the flow direction is affected by perennial tributaries (Adams and Bergman, 1996). The water-level elevation contours were digitized from a mylar map at a scale of 1:250,000 from the U.S. Geological Survey publication, "Geohydrology of alluvium and terrace deposits of the Cimarron River from Freedom to Guthrie, Oklahoma" by Adams and Bergman (1996). The maps were published at a scale of 1:900,000. Reviews Applied to Data -- This electronic report was subjected to the same review standard that applies to all U.S. Geological Survey reports. Reviewers were asked to check the topological consistency, tolerances, attribute frequencies and statistics, projection, and geographic extent. Reviewers were given digital data sets and paper plots for checking against the source maps to verify the linework and attributes. The reviewers checked the metadata and a_readme.1st files for completeness and accuracy. Related Spatial and Tabular Data Sets -- This data set is one of four digital map data sets being published together for this aquifer. The four data sets are: > aqbound - aquifer boundaries > cond - hydraulic conductivity > recharg - aquifer recharge > wlelev - water-level elevation contours Digital map data sets of the Oklahoma surficial geology digitized from 1:250,000-scale maps (or 1:125,000-scale maps for the three Oklahoma panhandle counties) are published separately.

This data set was digitized from a map published at a scale of 1:250,000. The map represents the elevation of the water levels in the alluvial and terrace deposits along the Cimarron River from Freedom to Guthrie, Oklahoma, in 1985-86.Water-level elevations represented at this scale are indicative of broad, regional trends and should not be interpreted as site specific. The water-level elevation contours were digitized from a mylar-source map (33 inches by 31 inches or 84 centimeters by 79 centimeters), with a root-mean-squared-error (RMSE) of 0.008 map inches (0.020 map centimeters) or 167.49 feet (51.05 meters) ground distance.

Public UNCLASSIFIED None Operating System-- UNIX, ARC/INFO Version 7.0.3,(Mon Mar 13 22:21:55 PST 1995) Chain-node topology present. This data set includes the water-level contours published on figure 8, page 18 by Adams and Bergman (1996). None 64 meters Resolution as reported None. The water-level contours were digitized in three sessions with a maximum root-mean-squared error (RMSE) of 0.008 inches (0.020 centimeters) map distance or 167.49 feet (51.05 meters) ground distance. The contours were extended or clipped to meet the aquifer boundaries of the associated AQBOUND data set. The data set was edited to delete extraneous pseudo and dangle nodes. The ARC/INFO CLEAN command (ESRI, 1995), was used with a dangle length of 3,281 feet (1,000 meters) and fuzzy tolerance of 328 feet (100 meters). 1996 The registration tics used in the initial digitizing were township and range corners taken from 1:24,000-scale topographic maps. A comparison of a paper plot of the data set with the source map showed that the registration tics were not in the same locations on the 1:250,000-scale source map. To correct the problem, four 1:250,000-scale U.S. Geological Survey quadrangle maps were registered using latitudinal and longitudinal tics, with a maximum root-mean-squared-error (RMSE) of 0.003 inches (0.008 centimeters) map distance or 69.09 feet (21.06 meters) ground distance. Forty-four registration tics were selected and digitized from the quadrangle maps, and given the same tic identification numbers as the tics used initially. These new tics were used with the ARC/INFO TRANSFORM command (ESRI, 1995) to adjust the digitized tics to more closely match the source map. The root-mean-squared-error (RMSE) for TRANSFORM was 189.3 feet (57.7 meters) ground distance. 1996 The data set was changed from double to single precision with the ARC/INFO COPY (single) command (ESRI, 1995). The ARC/INFO CLEAN command (ESRI, 1995), was used to process the data set with a dangle length of 0.0 feet or meters and fuzzy tolerance of 53.8 feet (16.4 meters). Water-level elevation contours were attributed for ELEV and LTYPE. Verification of attribute codes were made by comparing a paper plot of the data set with the source map. 1996 Vector Point String 53 GT-polygon composed of chains Albers Conical Equal Area 29.5 45.5 -96 23 0.0 0.0 coordinate pair 64 meters 64 meters METERS North American Datum of 1983 Geodetic Reference System 80 6378137 298.257 WLELEV.AAT Arc attribute table ARC/INFO - Arc attribute table ARC/INFO - n/a n/a FNODE# Internal number of from-node Computed Sequential unique positive integer n/a n/a TNODE# Internal number of to-node Computed Sequential unique positive integer n/a n/a LPOLY# Internal number of polygon to left of arc Computed Sequential unique positive integer n/a n/a RPOLY# Internal number of polygon to right of arc Computed Sequential unique positive integer n/a n/a LENGTH Length of arc in coverage units Computed Positive real numbers n/a n/a WLELEV# Internal feature number Computed Sequential unique positive integer n/a n/a WLELEV-ID User-assigned feature number User-defined Integer n/a n/a ELEV Water-level contour elevation in feet above NGVD29 Adams and Bergman (1996) 950 1,650 MAJOR1 Water-level contour elevation in feet above NGVD29 Adams and Bergman (1996) 950 1,650 LTYPE Line type Adams and Bergman (1996) 1, 2 n/a n/a MINOR1 Line type Adams and Bergman (1996) 1, 2 n/a n/a Two attributes are associated with each line in this digital data set. The first attribute, ELEV, contains the elevation of the water-level contour, expressed in feet above the National Geodetic Vertical Datum of 1929 (NGVD29). The second attribute, LTYPE, contains the code 1, indicating the line is solid or the code 2, indicating the line is dashed on the source map. ELEV is stored in the first major code (MAJOR1) for lines, and LTYPE is stored in the first minor code (MINOR1) in the Digital Line Graph (DLG) version of this data set. See overview.
