Landsat 7 Data |
||||||||
The U.S. Geological Survey's Landsat 7 satellite provides medium-resolution image information of the Earth's surface. It is a multispectral scanner that collects visible, near-infrared, short-wave, and thermal infrared frequency bands from the sun-lit Earth. Nominal ground sample distances or "pixel" sizes are 49 ft (15 m) in the panchromatic band; 98 ft (30 m) in the 6 visible, near and short-wave infrared bands; and 197 ft (60 m) in the thermal infrared band. Original Landsat 7 data can be ordered for a cost of $600 per image from
the USGS via the
Data DownloadLandsat 7 data are in UTM NAD27 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 projections in Geographic Information System (GIS), therefore, all data have been reprojected into one standard projection, UTM NAD27 zone 10 projection, for the Lake Tahoe Basin.
