U.S. Geological Survey http://pubs.water.usgs.gov/wri0114195 The digital data set provides point locations and general descriptions of areas photographed to document sites visited during a study to refine current estimates of ground-water discharge from the major discharge areas of the Death Valley regional flow system. Photographs were taken 1994-99. Sites were used as controls to better improve the delineation of ET (evapotranspiration) units classified using spectral methods throughout each of the major discharge areas. The digital data set was created to display site locations used to verify the classification of ET units throughout the major discharge areas of Death Valley regional flow system. Introduction The digital data set was created in cooperation with the U.S. Department of Energy. The data set was created as part of a study to refine current estimates of ground-water discharge from the major discharge areas of the Death Valley regional flow system. Reviews The digital data set has gone through a multi-level, quality-control process to ensure that the data are a reasonable representation of discharge-area boundaries. Reviewers were asked to check metadata and other documentation files for completeness and accuracy. Reviewers also were asked to check the topological consistency, tolerances, projections, and geographic extent.

Although the data set has been used by the U.S. Geological Survey, U.S. Department of the Interior, no warranty expressed or implied is made by the U.S. Geological Survey as to the accuracy of the data and related materials. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology. Users should exercise caution and judgment in applying these data, and be aware that errors may be present in any or all of the digital image data. If errors are encountered in this data set, it will be appreciated if the user would pass this information to the Metadata_Contact. 1994-1999 ground condition Complete None planned -117.10419165 -116.02922517 37.31834087 35.7995487 none ET unit vegetation soil evapotranspiration inlandWaters none southern Nevada eastern California Ash Meadows California Valley Chicago Valley China Ranch Death Valley Franklin Lake Franklin Well area Oasis Valley Resting Spring Sarcobatus Flat Shoshone Stewart Valley Tecopa none No use constraints apply.

Las Vegas NV 89119 USA 1-888-275-8747 (702) 897-4055 rlaczni@usgs.gov Compilation of this data set and the associated metadata was done in cooperation with the U.S. Department of Energy, Nevada Operations Office. IRIX64, 6.4, IP27 UNIX ArcInfo version 7.2.1 Multiple checks were performed to verify that each attribute represented its intended value. See Explanation. Where needed, an explanation is used to describe each attribute defined in the Entity_and_Attribute section. Point features present. See Supplemental Information. Horizontal accuracy is equal to that of the Precision Light-weight Global Positioning System (GPS) Receiver (PLGR) used to determine site locations. All coordinates rounded to nearest meter. Multiple visual checks were performed to verify that sites are located at their intended location. 30 meters Sites were located from UTM coordinates acquired with a PLGR. Coordinates were stored in an ASCII-text file and were used to generate an ArcInfo point coverage. The coordinates are considered accurate to about 30 meters. Location values for the monitoring sites were recorded, in the field, using GPS at time of visit. 19990601 1. UTM eastings and northings, and associated attributes were stored in a delimited ASCII-text file. 2. The ArcInfo utility CREATEPOINT was used to create an ArcInfo point coverage which contained all associated attributes and to build the associated topology. 3. Locations and attributes were verified by observation. 19990624 Point Point 210 Universal Transverse Mercator 11 coordinate pair 16.8055 16.8055 Meters North American Datum of 1927 Clarke 1866 6378206.4 294.98 PHOTO.PAT Point attribute table ArcInfo(R) GIS Software AREA Degenerate area of point ArcInfo computed Positive real numbers NA NA PERIMETER Degenerate perimeter of point ArcInfo computed Positive real numbers NA NA PHOTO# Internal feature number ArcInfo Computed Sequential unique positive integer NA NA PHOTO-ID Assigned feature number User Integer NA NA SITE_TYPE Type of site User C Control site User P Photo site User PHOTO_NO Unique identifier User Positive Character string NA NA X_UTM UTM easting coordinate of site User Integer NA NA Y_UTM UTM northing coordinate of site User Integer NA NA DATE Date photograph taken User Character string NA User DIS_AREA Discharge area identifier User AM Ash Meadows, Nev.
