The polygons were generated using guidelines set by the Standardized National Vegetation Classification System (October 1995). Original lines were drawn on a mylar overlay of printed 1:12,000 digital scale orthophoto quadrangles (DOQ), collected the summer of 2002. Hard copy 9X9 photography was used for photo interpretation. Traditional image interpretation cues were used to develop the polygons, such as shape, size, pattern, tone, texture, color, and shadow. Additional data layers were used in aiding the interpretation, such as slope, hydrology, geography, and ground-collected vegetation information. The lines developed in the image interpretation step were scanned using a large format scanner. The resultant scanned image was converted into line work for use within ArcGIS. The line work was cleaned, polygons created and attributed. The attributed vegetation classes were subjected to an accuracy assessment, following which final adjustments were made to the vegetation classes. As with any digital layer, this layer is a representation of what is actually occurring on the ground. Errors are inherent in any interpretation of ground qualities. Due to the "snapshot" nature of the DOQs, this vegetation layer reflects conditions that existed when the imagery was collected. This polygon layer represents vegetation communities found at the Natural Bridges 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\NABR\Vegetation\MU_PDFs\" & [MAP_UNIT_PDF]). 20020618 Source photography date Complete As needed Natural Bridges National Monument and environs -110.056245 -109.955472 37.641069 37.560518 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 Natural Bridges National Monument NABR San Juan County Utah UT Colorado Plateau National Park Service NPS USA National Park System Unit Name Thesaurus Natural Bridges National Monument National Park System Unit Code Thesaurus NABR 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

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 both in and surrounding Natural Bridges 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.

Imagery collection and publication. Two scales of aerial photography were flown, 1:40,000 (used for DOQ creation) and 1:12,000 (used for image interpretation). DOQs were printed in quarter quadrangle sheets(4), to facilitate line drawing. 20020618 Mylar overlay production. Mylar sheets were overlaid on DOQs. Traditional image interpretation techniques were used to draw lines on the mylar sheets. 9X9 aerial photography was used to assist in line placement. 20040101 Mylar scanning. Mylar sheets with line work were scanned using a large format scanner. The product of these scans was a .tiff image. 20040101 Polygon creation. 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 Accuracy assessment. An accuracy assessment was conducted using methods approved by the National Vegetation Classification guidelines. The accuracy assessment involved field plots determined by class size and number of polygons per class. 20040101 Revision and publication. Following the accuracy assessment, specialists examined the thematic accuracy of the vegetation layer. Adjustments were made to the data layer according to those assessments.

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.
