Publisher: NYS ITS GIS Program Office
Abstract:
These files contain 2001 digital orthoimagery in Putnam and Ulster counties, New York. Image pixel size is 1.0 ft. GSD. Image type is color infrared. Image horizontal accuracy is +/-4 ft. at the 95% confidence level. Each file contains an image covering 3000 ft. by 2000 ft. on the ground.
Purpose:
This digital orthoimagery can serve a variety of purposes, from general planning to field reference for spatial analysis to a tool for revision of vector maps. It can also serve as a reference layer for GIS.
Supplemental_Information:
Digital elevation models used for orthorectification where compiled from several sources, all of which were compiled photogrammetrically.
