Lewis County Contours

Contour zip file

The Lewis County contours were created using the FEMA Oneida Subbasin 2016/17 and USDA Lewis 2011 LiDAR Collections.

The USDA - Lewis 2011 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 FEMA - Oneida Subbasin 2016/2017 contours were delivered 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.
