The Lake Tahoe Data Clearinghouse Web site is part of the US Geological Survey's Lake Tahoe Initiative. The agency's goal for the site is to facilitate the coordination of research, monitoring, and environmental-management activities in the Lake Tahoe Basin and to ensure the widest possible access to data and information resulting from such activities. Products available include Digital Elevation Models, Digital Orthophoto Quadrangles, Digital Line Graphs, Digital Raster Graphics, maps and soil information of the area, and much more. The downloads include clear descriptions and examples for those unsure of the particular data types, making their use a snap for researchers, professionals, or anyone interested in the Lake Tahoe region.
