1975 - 1995 Black & White Aerial Index .pdf

The Greater Portland Council of Governments houses a valuable collection of aerial photography of the Cumberland County area. It is a rich resource of information for inventory, land use and growth analysis, site plan review, tax sheet and natural resource mapping. The collection includes 1975, 1976, 1986 and 1995 stereo image pairs as well as a color digital collection flown in 2001. All of the flights were flown to National Cartographic Standards.

They were flown in early Spring, at the time when most features are visible, and vegetation or snow would not prohibit contour mapping. These are stereo image pairs with a 60% north-south overlap and a 30% east-west overlap. Not more than 10% of any photograph or 5% of any one flight is obscured by cloud or dense cloud shadow.

For availability of 2001 color digital images, please refer to the accompanying index map.
