Abstract

A set of spatial data bases consisting of natural- resources and planimetric-base layers has been developed and documented for the Lake Tahoe Basin, California and Nevada. The data bases, in the form of geographic information system coverages, include surface geology, soils, timber type, riparian vegetation, land capability, stream channels, water bodies, roads, political boundaries, the Lake Tahoe Basin boundary, slope, aspect, drainage-basin boundaries, and hydrologic-monitoring sites. The data bases were developed from existing thematic maps, digital data, and hydrographic records. Data were compiled from maps and records of Federal, State, and local agencies. The scale of source materials ranged from 1:24,000 to 1:125,000 and their release dates. from 1964 to 1989. Documen- tation and summary information are included for each spatial data base.
