Northern Colorado Plateau Network, Inventory and Monitoring Program 20120328 vector digital data USGS-NPS Vegetation Mapping Program Canyonlands National Park Denver, CO USGS, Biological Resources Discipline, Center for Biological Informatics http://www1.usgs.gov/vip/cany/canygeodata.zip doi:10.5066/F7TH8JND This polygon feature class represents vegetation communities mapped at Canyonlands National Park. The polygons were generated using guidelines set by the Standardized National Vegetation Classification System (October 1995). A combination of methods were used to map Canyonlands. The USGS used e-Cognition software to create segments. The segments created were then looked at and extensively edited by the vegetation mappers. Some mapping was done on screen, using the 2002 imagery. 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 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 Canyonlands National Park. 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. Map Unit descriptions are hotlinked in the data, but the path names will need to be updated. 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\CANY\Vegetation\MU_PDFs\"& [MAP_UNIT_PDF]). 20020625 Source photography date Complete None planned Canyonlands National Park and environs -110.240406 -109.654268 38.511991 37.959146 None Community Association Vegetation Map Vegetation Classification Alliance NVCS SNVCS Standardized National Vegetation Classification National Park Service Theme Category Thesaurus Vegetation ISO 19115 Topic Category biota None CANY Utah Grand County Garfield County NPS National Park Service Wayne County Colorado Plateau San Juan County Canyonlands National Park USA UT National Park System Unit Name Thesaurus Canyonlands National Park National Park System Unit Code Thesaurus CANY None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae plants None Acknowledgment of e2M and the National Park Service would be appreciated in products derived from these data.

Hall, J. Von Loh, T. Belote, A. Wight, G. Wakefield, and A. Evenden 20120515 report http://science.nature.nps.gov/im/units/ncpn/ Network staff have 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 both in and surrounding Canyonlands National Park. 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. All data with a minimum mapping unit of 1/2 hectare that could be interpreted from the aerial photographs are entered into the digital database. Some classes under the MMU (minimum mapping unit) are included due to its ease of interpretation and due to the specialty of the class. The vegetation spatial data meets National Map Accuracy Standards.

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. 20070901 Revision and publication. Following the accuracy assessment, specialists analyzed the thematic accuracy of the vegetation layer. Adjustments were made to the data layer according to those assessments. 20110101 Polygon creation. Map unit polygons were created via segmentation routines using e-Cognition software. The routines were run, and the resulting polygons were then manipulated (merged/split etc.) as the mapper felt was necessary to break out the map classes. 20070101 Northern Colorado Plateau Network, Inventory and Monitoring Program Amy Tendick Vegetation ecologist unknown Moab UT 84532 435-719-2185 amy_tendick@nps.gov Imagery collection and publication.

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. OBJECTID - ObjectID - Sequential unique whole numbers automatically generated.
