Field data for the Vegetation Mapping Inventory Project of Gateway National Recreation Area
2003-2006. Field data for the Vegetation Mapping Inventory Project of Gateway National Recreation Area
This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. In 2003, a preliminary vegetation map of Gateway National Recreation Area was created showing NY ecological communities (Edinger et al. 2002) that was used to plan the vegetation plot sampling strategy. After plot sampling in 2003 and 2004, statistical analyses were conducted on these data in order to refine the classification and map. Prior to accuracy assessment (AA) field sampling, a revised preliminary map was created showing National Vegetation Classification (NVC) vegetation associations and Anderson Level II land cover classes. This revised map was used in spring 2006 to plan the thematic AA strategy. After AA field sampling in summer 2006, a final map was created in 2007 showing corrected NVC associations and Anderson II land cover classes. Thematic AA for the vegetation association map was calculated with a contingency matrix. The Kappa index for the 2006 revised preliminary map was 0.6201, with the overall percent accuracy calculated as 63.75%.
