Pre-LBA CABARE Mapped Land Surface and Vegetation Characteristics, Rondonia, Brazil

Surface parameter digital maps of vegetation, soil, and topography were obtained for Rondonia, Brazil, covering the 5x5 degree region bounded by 13-8 degrees S and 65-60 degrees W. Numerical maps of the natural landscape structure were prepared by digitizing existing 1:1,000,000 maps. Satellite data give information about the most recent modifications of the surface due to human activities. This mapping work was the first step of a mesoscale meteorological modeling program (Calvet et al., 1997) in forested and deforested Southwestern Amazonia (Rondonia, Brazil). This work was performed in the framework of a research program (CABARE) supported by the European Union, CEC Environment Program.

Data are provided in ArcGIS ArcInfo grid ascii format for the following surface parameters:

Elevation of terrain of the Rondonia region (altitude.txt)

LANDSAT-derived vegetation classification of the Rondonia region in 1993-1994 (classify.txt)

Soil classification of the Rondonia region (soil.txt)

Sand and Clay of the Rondonia region (sand.txt and clay.txt)

Vegetation classification of the Rondonia region from RADAMBRASIL (Macedo et al., 1979) (vegetation.txt)

巴西罗纳尼亚地区植被、土壤和地形表面的参数数字化地图已获取，覆盖了由南纬13-8度至西经65-60度所界定的5x5度区域。通过数字化现有的1:1,000,000比例尺地图，制备了自然景观结构的数值地图。卫星数据提供了关于地表因人类活动而发生的最新变化的信息。此次制图工作为罗纳尼亚地区（巴西）森林和砍伐森林的亚马逊西南部地区（Rondonia，巴西）的中尺度气象建模项目（Calvet 等人，1997年）的第一步。该研究是在欧洲联盟（CEC环境计划）资助的研究项目（CABARE）框架下进行的。

数据以ArcGIS ArcInfo网格ASCII格式提供以下表面参数：
