Abstract:

Location of thematic accuracy assessment sampling points, that were field sampled, based on the destination accuracy assessment points used in the vegetation mapping in Gateway National Recreation Area.

Purpose:

To identify the locations of the accuracy assessment points that were field sampled, and used to assess the thematic accuracy of the vegetation association maps in Gateway National Recreation Area.

Process_Step:

Process_Description:

From July 12 to October 19, 2006 each Accuracy Assessment Destination Point was located in the field using a Magellan SporTrak GPS unit (26 field days total). The datum on the GPS units was set to North American 1983 (Conus) and the coordinate system was set to Universal Transverse Mercator (UTM) zone 18. In most cases, three vectors (i.e., bearing and distance) were used to get within 10 m of AA destination points for open communities, or 20 m for forested communities, while remaining entitrely within the target polygon as best as possible. These cut-off levels were selected based on the plot size recommended for those types. Accuracy assessment data were collected digitally in the field using an iPAQ hand-held computer with data entry software (NY Natural Heritage Hand-Held Database - HHDB) and imported to the NY Natural Heritage Field Form Database (FFDB). 331 accuracy assessment points and 37 reference observation points were sampled at Gateway National Recreation Area in 2006.
