The cadastral property map (LBA-ECO LC-24 Cadastral Property Map of Uruara, Para, Brazil: ca.1975) was registered to this map and used to validate deforestation models based on the economic behavior of colonizers in the frontier.
The data was not assessed for accuracy. However, using unsupervised Isodata classes for Level I image classification using Landsat ETM+ imagery has been shown to be from 70-80% accuracy even without DEM correction (Lambin 1997, Mausel et. al. 1993, McCracken et. al. 1999).
The image was mosaicked from four Landsat ETM+ scenes acquired from August 3 to August 19, 1999, geo-referenced and projected to Universal Transverse Mercator, Zone 22 South, World Geodetic System 1984 datum.
This data is available through the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).
