Sample DEMLIDAR Data
LIght Detection And Ranging data. Elevation data with amazing accurarcy and very dense coverage. LiDAR data can be represented in many forms. Currently downloadable is the contour form (as shapefiles), the DEM form, the raw point form, and the edited point form of the LIDAR data. Breaklines used to generate the contours and DEMS are also available for the latest additions. Each quarter quadrangle has the four forms (and breaklines in the latest additions) and associated metadata files stored in a zip archive for downloading..)
