Landsat-based Global Urban Area Map

The Landsat-based Global Urban Area Map (LaGURAM) is a dataset of urban/non-urban classification map developed from time-series Landsat data provided by US Geological Survey. In the dataset, "urban" is defined with existence of built-up areas and pavement, a physical aspect of urban areas. The data is developed primarily for 1990, 2000, 2005, and 2010 although the target year can be flexible to users' request. The data has been initially developed for major cities of the world. The data will be improved in accuracy especially for regions of interest requested by end users. Please contact with the author if you have any interest in the LaGURAM dataset.

基于Landsat影像的全球城市区域地图（LaGURAM）是一款从美国地质调查局提供的时间序列Landsat数据中开发的城乡分类地图数据集。在该数据集中，“城市”一词定义为存在建筑区和铺装路面，这是城市区域的一个物理特征。数据主要针对1990年、2000年、2005年和2010年进行开发，尽管目标年份可根据用户需求灵活调整。该数据最初旨在为世界各大城市提供服务，并将针对终端用户请求的兴趣区域进行精度提升。如对LaGURAM数据集感兴趣，请联系作者。
