Global Agricultural Lands: Pastures, 2000

The Global Pastures data set represents the proportion of land areas used as pasture land (land used to support grazing animals) in the year 2000. Satellite data from Modetate Resolution Imaging Spectroradiometer (MODIS) and Satellite Pour l'Observation de la Terre (SPOT) Image Vegetation sensors were combined with agricultural inventory data to create a global data set. The visual presentation of these data demonstrates the extent to which human land use for agriculture has changed the Earth and in which areas this change is most intense. The data were compiled by Navin Ramankutty et al. (2008) and distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).

全球牧场数据集展现了2000年全球范围内用作牧场（用于放牧动物的用地）的土地面积比例。该数据集融合了中分辨率成像光谱辐射计（MODIS）和地球观测卫星（SPOT）图像植被传感器所获取的卫星数据，以及农业普查数据，旨在构建一个全球性的数据集。这些数据的视觉呈现揭示了人类土地利用对地球的改变程度，以及哪些地区的这种改变最为剧烈。该数据集由Navin Ramankutty等学者于2008年编纂，并由哥伦比亚大学国际地球科学信息网络中心（CIESIN）进行分发。
