Crosswalks to the NVCS were determined on 29 June 2007. This data set was created using field data that were collected to assess thematic accuracy of the preliminary vegetation map (cross-referenced below). Therefore, although estimated thematic accuracy of the preliminary vegetation map is known, thematic accuracy of this data set is untested. To provide an up-to-date digital geospatial vegetation database containing baseline 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. 2003 ground condition, based on 2003 vegetation plot field data, 2003 aerial photography, and 2006 thematic accuracy assessment field data.

PDF Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.0.1324 New York Natural Heritage Program 200804 vector digital data This shapefile is the preliminary (pre-accuracy assessment) vegetation map of Sagamore Hill National Historic Site. The Kappa index for the preliminary vegetation association map was 0.664, with the overall percent accuracy calculated as 71% +/- 21.1%, which is within the bounds of the stated goal of 80% mapping accuracy. Based on 17 accuracy assessment plots taken in the field, 7 of 9 (77.8%) initially mapped (and checked) associations meet the USGS/NPS vegetation mapping accuracy conformance standard of 80% (errors of commision). A total of 7 of 9 (77.8.%) associations encountered in the field during accuracy assessment meet the USGS/NPS vegetation mapping conformance standard of 80% (errors of ommision). Based on thematic accuracy assessment data, the preliminary vegetation association map was revised and corrected to create this data set. Therefore, thematic accuracy of this data set is assumed to be greater than that reported for the preliminary vegetation map. Re-assessing thematic accuracy of this data set would require another round of intensive field sampling. The costs of a second round of sampling do not seem justified simply to quantify the increased accuracy of the final map. Topology was checked. No overlaps or gaps were found. Shapefile covers entire park area. An initial vegetation map was developed for the park by first reviewing readily available, in-house 1995 color infrared National Aerial Photography Program aerial photos and then screen digitizing NY ecological community boundaries using 1994-99 digital orthophoto quarter quadrangles (DOQQs) as the base layer. Then, 23 vegetation plots were sampled in the park. These data were analyzed to determine the number and distribution of vegetation associations present in the park. Following vegetation plot data analysis, the initial vegetation map was edited and refined to produce the preliminary vegetation map attributed with the association names. 2006 Based on thematic accuracy assessment field data collected in October 2006 and the final classification of 9 vegetation associations, the preliminary vegetation map was revised to correct errors and create more accurate vegetation association polygon boundaries. In this final revision, accuracy assessment data, plot data, field observations, aerial photography signatures, and topographic maps were used to revise polygon boundaries and attributes. Polygons that were attributed with Anderson level II land use and land cover categories retained their attributes in the final map. 2007 Vector G-polygon 37 Universal Transverse Mercator 18 0.999600 -75.000000 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 sahi_veg_association Shapefile attribute table New York Natural Natural Heritage Program FID Internal feature number.
