No errors were detected. Includes only contours within the Raton Basin, Las Animas County, Colorado. Contours not well supported by data were deleted. Raster data were created from the contours of the altitude of the water table, using the ESRI ArcGIS ArcInfo command Topogridtool. 20060313 The raster data of the altitude of the water table was subtracted from the raster data of the land-surface altitude to create raster data of the depth to the water table. 20060313 Contours were generated from the raster data, using the ESRI ArcGIS ArcMap, Spatial Analyst Tools, Surface function, Contour. 20060313 Contours were clipped to the study area to coincide with the distribution of data points that were used to create the raster of the altitude of the top of the water table. 20060313 The contour lines were exported to a coverage, using the ESRI ArcGIS ArcMap Conversion Tools, Feature Class To Coverage command. 20060313 The coverage was edited using the ArcEdit module of ESRI ArcGIS ArcInfo Workstation. Editing consisted of deleting small closed contours and contours not supported by nearby data points, and manually reshaping contours. 20060313 The edited coverage was exported to a shapefile and the contours were smoothed, using the ESRI ArcGIS Data Management Tools, Smooth function. 20060313 Vector String 80 Albers Conical Equal Area 37.500000 40.500000 -105.500000 37.000000 0.000000 0.000000 coordinate pair 0.000128 0.000128 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 sir-06-5129_depth_water_table_con Contours showing generalized depth from land surface to top of Raton Formation U.S. Geological Survey Scientific Investigations Report 2006-5129 FID Internal feature number.
