Fly Dane

Fly Dane is a regional partnership that allows local agencies to pool their resources for periodic updates of orthophotography, elevation, and planimetric data.

1-foot Resolution Imagery:

The aerial photography will be acquired in the spring of 2005 at a scale of 1:20,000 (1"=1666'). The aerial photographs were used to create 1"=200' scale digital orthophotos at one-foot ground resolution covering all of Dane County, projected to the Dane County Coordinate System, and were divided into 313 four-square mile tiles.

Coverage Area:

Dane County

6-inch Resolution Imagery:

The aerial photography was acquired in the spring of 2005 at a scale of 1:10,000 (1"=833'). The aerial photographs were used to create 1"=100' scale digital orthophotos at six-inch ground resolution covering the majority of the urbanized areas in Dane County and consists of 305 one-square mile tiles.

4-foot Contours:

The digital four-foot contours are a vector data set developed from a ten-foot spaced grid, digital elevation model (DEM), with two-foot vertical accuracy. The contour data meets National Map Accuracy standards.

Coverage Area:

Dane County

2-foot Contours:

The digital two-foot contours are a vector data set developed from a densified digital elevation model (DEM), with one-foot vertical accuracy. The contours meet National Map Accuracy standards.

Terrain Data:

The DEM is a raster data set in ESRI GRID format with an X, Y, Z value located at the center of each 10ft. by 10ft. cell. The DEM has a ten-foot grid spacing with two-foot vertical accuracy. The DEM supports the development of four-foot contours at National Map Accuracy Standards. In 2005 only limited updates will be made to the terrain model in areas of significant change.
