The
OpenTopography project has just released over 10,000 km^2 of lidar data for the Oregon coast stretching from the California border through to the Columbia River. Lidar stands for Light Detection and Ranging, and uses laser beams in a similar fashion to radar to create high-resolution clouds of data, in this case topographic data.
The high resolution of lidar causes features that would normally be too subtle to be displayed on a old-fashion topo or even DEM (Digital Elevation Model) map to "pop" out. Who wants to find those faults?
