Bare-Earth Digital Elevation Models (DEM)
Web Services

GIS web services allow users to connect to data sources through the internet rather than downloading and storing copies of the data on their own systems. The NYS ITS GIS Program Office is pleased to provide access to statewide bare-earth DEM coverage through web services. Users are encouraged to use the services to display and analyze the DEM in their desktop GIS and web applications.

All available NY State DEM data are available through web services hosted by the NYS ITS GIS Program Office. The service is hosted on image server so it will allow the end user to not only view the raster DEM but also run some analytics (generate contours, hillshades, etc.) and download portions of the data.




High Resolution DEMs and 2 ft. Contours are currently unavailable for download. We will make an announcement on the GIS-List serve when files are back online. . #js_notify#
