Digital color infrared orthophotography of Block Island, Rhode Island, as well as collateral data of soil and terrain information, were used to model vegetation distributions on the island (see paper by Duhaime et al., pp. 1295-1302). The photography was recorded on Kodak 2443 Aerochrome film at a scale of 1:40,000 from an altitude of approximately 6.1 km. Two overlapping stereo photos were scanned at a density of 315 lines/centimeter, and the digital representation was processed to create a seamless orthophotograph of the island. Aerial photography and creation of the digital orthophotography was performed by Photo Science, Inc. of Gaithersburg, Maryland.
