Katahdin Woods and Waters National Monument 4-Band Aerial Collection

Submitted by atripp on

The primary objectives of the Katahdin Woods and Waters National Monument (KAWW),Maine, mapping project were to provide the following: an accurate, tested, and up-to-date vegetation map; a vegetation classification standardized to the U.S. National Vegetation Classification and supported by vegetation plot data collected within the Monument; and a field key to vegetation for the entire monument. The fulfillment of these project goals will allow the Monument to make informed management decisions for KAWW, which is a potential location for a living history timber management demonstration area and associated visitor amenities. The report products will present the Monument with an up-to-date inventory of vegetation types within KAWW and provide descriptive botanical and ecological information that can be referenced to locations in a geodatabase. The USGS Upper Midwest Environmental Sciences Center, in coordination with the U.S. Fish and Wildlife Service, conducted the mission planning, aerial image acquisition, processing from raw to 4-band (red, green, blue, near-Infrared) images, and vegetation maps. The images were collected at 0.15-meters (6 inches) per pixel using co-located Phase One iXU-RS180 camera set in a gyro-stabilized SOMAG mount that can be directly georeferenced using simultaneously generated exterior orientation (X, Y, Z expressed by GPS and roll, pitch, and yaw as detected by the inertial measurement unit).
