Tri-Decadal Global Landsat Orthorectified mosaic data collections are derived from a global set of high-quality, relatively cloud-free orthorectified TM imagery from Landsat 4 and 5.

Tri-Decadal Global Landsat Orthorectified TM Mosaics
The average acquisition date for the Tri-Decadal Global Landsat Orthorectified TM data is 1990 (+/- 3 years). However, individual scenes may range from 1985 to 1996. These Landsat data have been orthorectified, using geodetic and elevation control data to correct for positional accuracy and relief displacement. Large blocks of Landsat data were adjusted through a patented procedure using pixel correlation to acquire tie-points within the overlap area between adjacent Landsat images. The Landsat TM scenes were mosaicked by matching individual histograms and feathering overlapping areas together to create a TM Mosaic product. The mosaics are contrast enhanced color image data products comprised of Landsat TM bands 7, 4, 2 composited in red, green, and blue, respectively. The resulting mosaics are made up of several Landsat scenes covering a 5-degree (north-south) segment of a standard, 6-degrees (east-west), UTM partition. The Tri-Decadal Global Landsat Orthorectified TM Mosaic data collection consists of approximately 500 TM (Landsat 4-5) mosaics.
