Summary
The goal of this project was to develop a digital orthophoto mosaic and a digital geospatial vegetation database for Appomattox Court House National Historical Park (APCO). For this project, vegetation was classified to the formation level using the National Vegetation Classification System developed by The Nature Conservancy and the network of Natural Heritage Programs.
Creation of the orthophoto mosaic and the vegetation database involved:
-
Scanning, orthorectifying, and mosaicking 1:6,000 scale colorinfrared aerial photography provided by the National Park Service (NPS);
-
Developing a list of vegetation formations for APCO from The Nature Conservancy's Terrestrial Vegetation of the United States
-
Classifying aerial photographs provided by the NPS to the formation level using the National Vegetation Classification System;
-
Assessing positional accuracy of the orthophoto mosaic and thematic accuracy of the digital vegetation database; and
-
Developing FGDC compliant metadata for both databases.
This report describes the methods and materials for performing these tasks and includes the results of the accuracy assessments. More detailed descriptions of each component of the project are contained in the Master's thesis, "Development of a Digital Protocol for Vegetation Mapping," by Melani Hix Harrell that is appended to this report.
