Crosswalks to the NVCS were determined on 29 June 2006. To provide an up-to-date digital geospatial vegetation database containing base line information about the park's vegetation associations to the park's resource managers in order to ensure effective, long-term management of the natural resources held in trust. 20060831 20060831 Complete None planned Delaware Water Gap National Recreation Area and environs -75.169710 -74.745841 41.346599 40.940703 none vegetation association vegetation classification National Park Service vegetation map vegetation alliance vegetation formation none Delaware Water Gap National Recreation Area Pennsylvania New Jersey none Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae none none Pennsylvania Natural Heritage Program Ecologist mailing and physical address

Middletown Pennsylvania 10755 USA (717) 948-3962 (717) 948-3957 Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.4.1420 The Kappa index for the preliminary vegetation association map was 55.0% +/- 2.5%, with the overall percent accuracy calculated as 56.1%. The Kappa index and errors of commission and omission reported for the vegetation association map and many vegetation associations fall below the USGS/NPS vegetation mapping protocol requirement of 80%. However, this low level of accuracy is typical for vegetation mapping efforts of large parks. Based on the thematic accuracy assessment data, the preliminary vegetation association map was revised and corrected to create the final vegetation association map depicted in this shapefile. Therefore, the thematic accuracy of this final vegetation association map is greater than that reported above for the preliminary vegetation association map. However, re-assessing the thematic accuracy of the final vegetation association map would require another round of intensive field sampling. The costs of a second round of sampling do not seem justified simply to quantify the level of increased accuracy in the final map. Check Topology script was run on shapefile in ArcView 3.2. No silvers or gaps were found. Shapefile covers entire park area. A vegetation cover type map was delineated from a 2002 digital aerial photo mosaic. Then, 251 vegetation plots were sampled in the park. These data were analyzed to determine the number and distribution of vegetation associations present in the park. The vegetation cover type map was then revised and attributed with the association names. Then 1,130 thematic accuracy assessment points were randomly placed within the association map, following a stratified random sampling plan. Based on the accuracy assessment data, the association map was revised further. 20060831 Five polygons were identified to contain sensitive information and were merged into surrounding polygons to protect the location information 20070201 Vector G-polygon 4682 Universal Transverse Mercator 18 0.999600 -75.000000 0.000000 500000.000000 0.000000 coordinate pair 0.000016 0.000016 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 DEWA_Vegetation_2006_public Shapefile attribute table Pennsylvania Natural Heritage Program FID Internal feature number.
