Over recent years, massive amounts of remotely sensed data has become available on the internet. These data sources are essential for understanding the materials being sensed, the sensors used, and the results of remote sensing.

 

 

    NASA has made much of its data available to the public. Although not at extremely high resolutions, the data is adequate for getting the feel for working with satellite imagery. There are also a variety of other organizations that compile publicly available satellite data:

 

- http://landsat.usgs.gov/band_designations_landsat_satellites.php - A useful FAQ by the USGS on band designations for the Landsat missions (sensor, wavelength, resolution)

 

- http://glcfapp.glcf.umd.edu:8080/esdi/index.jsp - The Global Landcover Facility is an excellent resource for publicly available satellite data, search by path and row, or by location

 

- http://web.pdx.edu/~emch/ip1/bandcombinations.html - An informative web page on different Landsat band combinations. Gives a run-down on which bands to combine for different land cover types

 

- http://www.pancroma.com/data.html - Another satellite data depot, includes satellite data, DEMs, and useful resources
