The geographic information system (GIS) format spatial data set of vegetation for Grand Portage National Monument (GRPO) was created by the National Park Service (NPS) Vegetation Inventory Program (VIP). The GRPO covers an area of approximately 291.8 ha (721.1 acres). The map classification scheme used to create the vegetation data set is designed to represent local plant communities at the finest level possible using the National Vegetation Classification System. Physiognomic information was also recorded, including tree height, canopy density, and coverage patterns. The vegetation data set was developed by interpreting aerial photographs collected in 2006 and extensive field surveys. Individuals who cooperated...
The geodatabase contains 13 relate tables that together provide updated and synchronized classifications to an existing vegetation map layer for each of the nine park units in the Great Lakes Network (GLKN) of the National Park Service (NPS) Natural Resource Inventory and Monitoring Program. The classifications include 1) vegetation types at every hierarchical level in the 2015 version of the U.S. National Vegetation Classification (USNVC) and 2) map classes that represent vegetation and land cover in the vegetation map layers. Furthermore, the tables provide a crosswalk between the two classifications (vegetation and map). Each park unit in GLKN has received, at different times over several years, vegetation data...
