Description:

Abstract: 

These files contain 2004 leaf-off digital orthoimagery of Albany, Rensselaer, Saratoga and Schenectady counties in New York. Image pixel size is 2 ft. GSD. Image type is color infrared. Image horizontal accuracy is +/-8 ft. at the 95% confidence level.  Each file contains an image covering 6000 ft. by 4000 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 were compiled from several sources, all of which were compiled photogrammetrically.
