Summary

Tetra Tech, under contract with the City of Cheyenne, Wyoming, provided 12-inch resolution imagery to cover a 2,686 square mile area of the City of Cheyenne and Laramie County, Wyoming. The mapping will benefit the Cheyenne and Laramie County Cooperative GIS Program members.

 

Description

An orthoimage is aerial image data that has been orthorectified, i.e. displacement of features on the ground caused by terrain relief and sensor geometry have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. Aerial imagery was acquired with an UltraCam Falcon digital camera with 4 spectral bands (red, green, blue and near infrared). For this dataset natural color orthoimagery (red, green, blue) was produced with 1 foot ground resolution.The spatial reference is the US State Plane Coordinate System, zone Wyoming East (4901), horizontal datum NAD 83 (2011) epoch 2010, in US Survey Feet. The design is to meet National Map Accuracy Standards for 1"=200' mapping. The imagery for the 1 ft resolution imagery was acquired between June17th and July 19th, 2014. The imagery is delivered in uncompressed geotiff and in tifjpeg compressed tiles and as a complete mosaic in Lizardtech mrsid mg4 format.
