Land Cover Data
The U.S. Geological Survey, in cooperation with many other Federal agencies,
is building a nationwide dataset of land cover. The dataset includes information
from LandSat satellites as well as many ancillary sources such as census
statistics. The dataset for California and Nevada is still being verified,
but a preliminary view is below. More information on the National Land
Cover Dataset is available at

The following land cover data have been mosaicked together from the18 7.5-minute quadrangles that cover the Lake Tahoe Basin. The mosaicked files are more convenient for looking at areas throughout the basin or areas on the edge of two quadrangles.

Land cover data are in UTM NAD83 zone 10 projection. Raw (original) data are in the following projections: data east of 120 degrees longitude are in UTM zone 11 and data west of 120 degrees longitude are in UTM zone 10. It is not possible to combine different UTM zones in Geographic Information System (GIS), therefore, all data have been reprojected into one standard projection, UTM NAD83 zone 10 projection, for the Lake Tahoe Basin.
