Free Data

Free satelite data is available from an increasing number of sources. Here are the most important archives and other useful data:

Sample Data for Experimenting with PANCROMA:

• Zipped Sample GeoTiff Band Files 1,2,3 PAN for experimenting with RGB color composites and pan sharpening. These are subset files from a full sized Landsat data set.

• Zipped Landsat Sample GeoTiff Band Files Bands 1,2,3,4,5 and 7 for experimenting with PANCROMA Spectral Analysis utilities.

• Use these Landsat Sample GeoTiff Band File Sets for Gap Filling in order to experiment with the gap filling routines. The zip file contains six images subsetted and matched using PANCROMA.
