LIDAR for Northeast Proposal

You can download the proposal from http://megis.maine.gov/docs/LiDAR_for_Northeast.pdf
The Maine Office of GIS, in cooperation with USGS, the State Planning Office, Maine Department of Transportation, the Maine GeoLibrary Board, and UNH, have developed a proposal for stimulus funding to collect LiDAR data for all coastal counties in New England. LiDAR (light detection and ranging) is a highly-precise method of measuring topography, using a laser emitted from an airborne sensor which pulses at various intervals and produces highly accurate elevation contour lines and digital elevation models. For example, Maine currently uses contour lines in intervals of 20 feet, with a vertical accuracy of +/- 10 feet, for floodplain mapping. LiDAR can produce contours that measure elevation in one-foot increments with vertical accuracy of +/- 15cm. The proposal is currently being circulated to GIS contacts throughout the region and is receiving wide support.
