GRS was selected by National Park Service to create a detailed land-cover map of the Wrangell-St. Elias National Park and Preserve. This 18-million acre park and preserve is the largest U.S. National Park and is characterized by its rugged terrain including magnificent mountains, glaciers, river valleys, and coastal shoreline. 
GRS developed a comprehensive Project Plan and the establishment of necessary database tables, files, procedures, and processes. Fieldwork and aerial surveys were accomplished during the summers of 2004 and 2005 with some additional field assessment in the
summer of 2006. The project also incorporated existing field data that were collected in prior field surveys by agency and contracted personnel. The final map was completed in late 2007 and was formally delivered to the NPS and accepted. The resulting map contains detailed qualitative data including species composition and vegetation structure with over 2000 vegetation strata.
