LBA Regional Boundary for the Amazon and Tocantins River Basins, 5-min

This data set is an expanded version of the Costa et al. (2000) data set and consists of a single grid with values of 1 for cells within the basins and 0 for cells outside. The resolution of the data set is 5 x 5 min (approximately 9 x 9 km). The area of this data set is consistent with the study area of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) in South America. The data file is in ASCII GRID format.本数据集为Costa等人（2000）发布数据集的扩展版本，由单一网格构成：流域范围内的网格单元赋值为1，流域外的网格单元赋值为0。本数据集的空间分辨率为5分×5分（约9千米×9千米），其覆盖范围与南美洲亚马孙大规模生物圈-大气实验（Large Scale Biosphere-Atmosphere Experiment in Amazonia, LBA）的研究区域保持一致。数据文件采用ASCII GRID格式。
