Shenandoah National Park 200910 vector digital data http://www1.usgs.gov/vip/shen/shenplot.zip John Young Gary Fleming Wendy Cass Chris Lea 2009 technical report doi:10.5066/F7DB7ZTS This data set is an ESRI point shapefile. Points represent vegetation and accuracy assessment plots from which field data were collected as part of the Version 2.0 vegetation mapping project at Shenandoah National Park. Point features include 352 points that represent vegetation plots used in the quantitative analysis for this project: 208 plots collected from 2001-2003 for the Version 1.1 park vegetation map; 14 plots sampled during the summer of 2007; 27 plots sampled for the Rock Outcrop Management Plan inventory project (2005-2007); and 103 plots sampled by the Virginia Natural Heritage Program (1990-2000). Two hundred ninety-three (293) point features represent plots sampled during the Version 1.1 accuracy assessment that were used in this effort to evaluate and assess vegetation distribution and composition. The remaining 703 points represent accuracy assessment plots from which field data were collected in the summer of 2008. Data from these 703 plots were used to assess the accuracy of the Version 2.0 vegetation map. This shapefile was created from data contained in the Microsoft Access NPS PLOTS database, one of the data products of the Version 2.0 vegetation mapping project at Shenandoah National Park. 1990 2008 Ground condition Complete None planned Shenandoah National Park and environs -78.850888 -78.151168 38.919309 38.025351 ISO 19115 Topic Category environment National Park Service Theme Category Thesaurus Vegetation None Plot vegetation map National Park Service vegetation classification vegetation classification accuracy assessment National Park System Unit Name Thesaurus Shenandoah National Park National Park System Unit Code Thesaurus SHEN None Virginia Blue Ridge Mountains None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae None None Shenandoah National Park Wendy B.

PDF Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.1.3000 All point features are unique. There are no duplicate points. Each record in the Plots and AA Observations tables in the PLOTS database is represented by one point. This point shapefile was created using data from the Plots and AA Observations table in the PLOTS database. Coordinates were taken from the - Field UTM X - and - Field UTM Y - fields in the tables, along with other selected fields. These data were exported from the MS Access database, converted to an Excel file, edited, and added to ArcMap. In ArcMap the - Make XY Event Layer - tool was used to convert the table data to an event layer which was then exported to a shapefile. 20091030 Vector Entity point 1348 Universal Transverse Mercator 17 0.999600 -81.000000 0.000000 500000.000000 0.000000 coordinate pair 0.000001 0.000001 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 shen_vegmap_v2_veg_plots_points Shapefile attribute table Shenandoah National Park FID Internal feature number ESRI Sequential unique whole numbers that are automatically generated.
