LC-24 (Walker / Reis)

LBA Dataset ID:

LC24_LAND_COVER_SOUTHERN_PARA

2. CALDAS, M.M.
      3. ARIMA, E.Y.
4. ALDRICH, S.P.

Dataset Abstract:

These data were used in 2007 to illustrate the nature of deforestation in the South of Para, Brazil over the past twenty years.
Simmons, et. al. Figure 7 shows the change in forest cover on a settlement, 17-April in the South of Para, as an example of the potential land-cover impacts of direct action land reform. 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.

Data Characteristics (Entity and Attribute Overview):

Data Characteristics:

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.





Data files are as follows:


Southern_Para_LandCover_1984.e00


Southern_Para_LandCover_1988.e00


Southern_Para_LandCover_1996.e00


Southern_Para_LandCover_2003.e00

Data Application and Derivation:

These data were used to illustrate the nature of deforestation in the South of Para over the past twenty years. Especially of interest was deforestation associated with the establishment of new smallholder agricultural settlements.

Quality Assessment (Data Quality Attribute Accuracy Report):

Quality Assessment:

No formal accuracy assessment has been undertaken with regards 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.

Process Description:

Data Acquisition Materials and Methods:

This data is a k-means classification of rough land-cover for the South of 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 5 classes using visual comparison (Water, Clouds/Shadow, Forest, Not Forest, Background).
