This data set is a five-class land cover for Southern Para for the years 1984 (Landsat MSS), 1988 (Landsat TM), 1996, and 2003 (Landsat ETM+). The final classification shows five classes derived using visual comparison (Water, Clouds/Shadow, Forest, Not Forest, Background). These data were used in 2007 to illustrate the nature of deforestation in Southern Para, Brazil over the past twenty years (Simmons et al. 2007). There are four annual GeoTIFF files distributed with this data set. Each GeoTIFF file and accompanying *.tfw file have been compressed into a single *.zip file.

This data set is a five-class land cover for Southern Para for the years 1984 (Landsat MSS), 1988 (Landsat TM), 1996, and 2003 (Landsat ETM+). The classification shows five classes using visual comparison (Water, Clouds/Shadow, Forest, Not Forest, Background). These data were used in 2007 to illustrate the nature of deforestation in Southern Para, Brazil over the past twenty years. The data show similar trends on many of the more than 100 official settlement-projects in the region that have been established by the government land-reform agency.
Related Data Sets:
The 1984 Landsat MSS scene was acquired from the University of Maryland's Global Land Cover Facility in a pre-processed form and was co-registered with the more accurate 2003 imagery (using 10 ground-control points collected in the Summer of 2006). Landsat TM and ETM scenes were acquired from TRFIC and Landsat.org and were coregistered to the 2003 imagery. There are four annual GeoTIFF files distributed with this data set. Each GeoTIFF file and accompanying *.tfw file have been compressed into a single *.zip file.

The data have been used to illustrate the nature of deforestation in Southern Para over the past twenty years. Especially of interest is deforestation associated with the establishment of new smallholder agricultural settlements (Simmons et al. 2007).
No formal accuracy assessment has been undertaken with regard to attribution. It is possible, indeed, likely, that there are errors of commission and omission in the resulting classification. Spatial accuracy after georectification of the 1984 scene was good, RMSE less than 0.8.
This data is a k-means classification of rough land-cover for Southern Para for the years 1984 (Landsat MSS), 1988 (Landsat TM), 1996, and 2003 (Landsat ETM+). The classification was developed on 20 classes separated out over a maximum of 500 iterations of the k-means algorithm. The resulting 20 classes were collapsed into five classes using visual comparison (Water, Clouds/Shadow, Forest, Not Forest, Background).
