Future Goals of New York Statewide Elevation Program - Continue to make available existing data - Continue to create and publish 2 foot contours - Create a Contour Web Service - Create a DEM Web Service - Get statewide Coverage of LiDAR within the next 3-4
years - Re-Collect LiDAR data in the “Questionable Areas” - Find a way to distribute the LAS point clouds to the
public
