Essex County 2-ft Contours
The Essex County contours were created using a combination of the NYSGPO Warren, Washington Essex 2014/15 LiDAR Collection and the USGS Clinton, Essex, Franklin 2014/15 LiDAR Collection.
The NYSGPO Warren, Washington, Essex 2014/15 portion of 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.The USGS Clinton, Essex, Franklin 2014/15 portion were delivered as a subset of the LiDAR Collection. These contours were delivered on as individual tiles, to make the contours more useable and distributable the GIS Program Office merged the tiles by town and clipped them to a 200ft buffer of the town. The contours were then imported into a file Geodatabase where they are stored by town and have several contour intervals the end-user can choose from including 1ft, 2ft, 10ft, 20ft, 50ft, 100ft, 250ft, and 500ft with a scale triggered layer file.
