Imagery data for the Vegetation Mapping Inventory Project of Minute Man National Historical Park

This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here.

On April 28, 2003, William Frament, USDA Forest Service (Northeastern Area State and Private Forestry, Durham, NH), acquired leaf-off (non-growing season) color infrared (CIR), stereo pair 1:8,000 scale aerial photography of MIMA. The photography was acquired as part of a larger project flown for several eastern national parks at one time, and thus preceded the vegetation classification and mapping project. The photography was captured in late April when deciduous trees were mostly bare and the ground was generally free of snow. The image type consists of a raster 3-band color image. The bands are blue, green, and near infrared. Each pixel contains a value ranging from 0 to 255 per band. Digital Orthophoto Quarter Quadrangle (DOQQ) images (1:5,000 Color Ortho Imagery, April 2001) were obtained from the Office of Geographic and Environmental Information of the Commonwealth of Massachusetts Executive Office of Environmental Affairs (MassGIS). These were combined to create a single mosaic file for use as ground control.
