The Pittsburgh District is part of the Great Lakes and Ohio River Division of the U.S. Army Corps of Engineers. The District’s Geospatial Section gathers data and information through means such as land surveys, hydrographic surveys, LIDAR, and more. This information is processed and used to create maps, drawings, models, and simulations of different geospatial features. The purpose of this site is to provide you access to our geospatial data and the resources of our district. If you have any questions, comments, or suggestions, send us an email. We'd love to hear from you!
