Global Agricultural Lands: Croplands, 2000

The Global Croplands data set represents the proportion of land areas used as cropland (land used for the cultivation of food) 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).

全球耕地数据集表征了2000年用于耕作（即种植食物的土地）的土地面积比例。该数据集融合了中分辨率成像光谱仪（MODIS）和地球观测卫星（SPOT）图像植被传感器的卫星数据，以及农业清查数据，旨在构建一个全球性数据集。这些数据的可视化展示揭示了人类土地利用对地球农业的影响范围，以及变化最为剧烈的区域。该数据集由Navin Ramankutty等人（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）分发。
