Chautauqua County Contours
The 2 foot contours were generated by NYSGPO using the Southwest 2017 Spring LiDAR Collection. These contours were generated using Global Mapper Generate Contours tool and running against the bare earth digital elevation model. Contours are stored within a File Geodatabase by town, each town has several contour intervals the end-user can choose from including 2ft, 10ft, 20ft, 50ft, 100ft, 250ft, and 500ft with a scale triggered layer file.
