Northern Colorado Plateau Network, Inventory and Monitoring Program 20080321 vector digital data USGS-NPS Vegetation Mapping Program Hovenweep National Monument Denver, CO USGS, Biological Resources Discipline, Center for Biological Informatics http://www1.usgs.gov/vip/hove/hovegeodata.zip doi:10.5066/F73X84MM This polygon feature class represents vegetation communities mapped at Hovenweep National Monument. The polygons were generated using guidelines set by the USGS-NPS Vegetation Mapping Program (http://www.usgs.gov/core_science_systems/csas/vip/standards.html). Original vegetation map unit lines were drawn on mylar overlays of the project photography, then scanned to generate the linework. Due to the "snapshot" nature of the aerial photography, this vegetation layer largely reflects conditions that existed when the imagery was collected (August 1996). This polygon layer represents vegetation communities found at the Hovenweep National Monument. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation. To update the hotlinks to the map unit description PDFs, update the MAP_UNIT_PDF_PATH field in TBL_VEGMAP_INFO with the directory path where the map unit PDFs are stored (e.g., Calculate: MAP_UNIT_PDF_PATH = "C:\GIS\Parks\HOVE\Vegetation\MU_PDFs\" & [MAP_UNIT_PDF]). 19960806 Source photography date Complete As needed Hovenweep National Monument and environs -109.186447 -108.721512 37.447231 37.290602 None Vegetation Classification Standardized National Vegetation Classification SNVCS NVCS Alliance Community Association Vegetation Map National Park Service Theme Category Thesaurus Vegetation ISO 19115 Topic Category biota None Hovenweep National Monument HOVE San Juan County Utah UT Montezuma County Colorado CO Colorado Plateau National Park Service NPS USA National Park System Unit Name Thesaurus Hovenweep National Monument National Park System Unit Code Thesaurus HOVE None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae None None Northern Colorado Plateau Network, Inventory and Monitoring Program Janet Coles Vegetation Ecologist Mailing Address

Reid, and J. Coles 200803101 report http://science.nature.nps.gov/im/units/ncpn/ Network staff has ground checked and verified all features to the best of their knowledge. GIS personnel verified all features and attributes. All polygon features are checked for topology using the ArcGIS software. There are no duplicate features present. The tests for logical consistency are performed in ArcGIS. All attribute codes and attributes have been checked for typographical and logical errors. This data contains all the polygons mapped in Hovenweep National Monument. All data in the project area were classified and digitized. This includes alliances/community association classes, density classes, height classes, pattern groups, water, and unvegetated/landuse. The vegetation spatial data meets National Map Accuracy Standards. Not applicable USGS varies digital file 24,000 CD-ROM unknown publication date DRG Digital Raster Graphics were used for field maps.

Imagery collected (1996) at a scale of 1:12,000. These hardcopy photos were scanned, then rubbersheeted for use as the base map. unknown Polygon creation. Vegetation map units were drawn onto mylar overlays over 9X9 hardcopy photos. These overlays were then scanned, then the digital images of mylar sheets were brought into ArcGIS. They were converted from images into line feature classes using ArcScan. The line feature classes were cleaned and converted into polygons. The polygons were examined for topology, and were then attributed using map codes written on the mylar sheets. 20040101 Revision and publication. Following the initial vegetation mapping, specialists examined the thematic accuracy of the vegetation layer. Adjustments were made to the data layer according to those assessments. 20070101 Vector G-polygon 408 Universal Transverse Mercator 12 0.999600 -111.000000 0.000000 500000.000000 0.000000 coordinate pair 0.000100 0.000100 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 fcl_Veg_Polys Feature Class National Park Service OBJECTID Internal feature number.

The upper levels of the hierarchy are based on the physical form or structure of the vegetation (physiognomy) and have been refined from the international standards developed by the United Nations Educational, Scientific, and Cultural Organization (UNESCO). The two most detailed levels of the hierarchy are based on the species composition of existing vegetation (floristics) and reflect the phyto-sociological standards that were originally developed by European ecologists. The vegetation classification is continually advanced through the collection and analysis of new field data and will be greatly strengthened during the course of the USGS/NPS mapping efforts. Data file attributes include vegetation height, density, species, alliance, community element, and land cover.
