          Title: Vegetation Classification and Mapping at Allegheny Portage Railroad National Historic Site
          Geospatial_Data_Presentation_Form: document
  Description:
    Abstract: Vegetation map of Allegheny Portage Railroad National Historic Site provides local park-specific names for vegetation types, as well as crosswalks to the National Vegetation Classification System (NVCS), including association, alliance and formation level attributes.  Crosswalks to the NVCS were determined on March 7, 2006.
    Purpose: 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.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: The Kappa index for the vegetation association map was 68.7% +/- 6.9%, with the overall percent accuracy calculated as 72.4%.
  Logical_Consistency_Report: Check Topology script was run on shapefile in ArcView 3.2.  No silvers or gaps were found.
  Completeness_Report: Shapefile covers entire park area.
  Lineage:
    Process_Step:
      Process_Description: A general cover-type vegetation map was delineated from interpretation of the 2003 digital aerial photo mosaic.  Seventy-seven 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.  One hundred thirty-four 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.
