Aerial Photographs
The City periodically has aerial photographs taken of the entire area contained within the corporate limits; these photographs are used at the base map for many planning and design efforts, and are also used as a tool to monitor the pace of development within the City. The latest set of photographs was taken in 2006; they are color photographs with a 6” pixel resolution, and have been geo-referenced to the City’s datum. It is also possible to produce topographic mapping at a 2’ contour interval from these photographs.

Purchase
The photographs are available for sale in digital or hard copy format. Topographic mapping has also been produced for certain areas in the City, and is available for sale as well. Upon request, the City can also produce topographic mapping for areas not previously mapped; pricing depends upon the size of the area to be mapped, and the density of features in that area.
