青藏高原土地覆被数据（2012）

本数据集是2012年青藏高原地区的土地覆被数据，数据为栅格TIFF格式，空间分辨率为300米，包含耕地、林地、草地、水体、城市用地等22个大类，可用于青藏高原城镇化与生态环境交互胁迫的地理本底研究。该数据来自欧空局CCI-LC项目生产的土地覆被数据产品。该数据集采用了WGS84的地理坐标系统，有22个大类。数据的生产融合多种卫星数据资料，包括MERIS FR/RR，AVHRR，SPOT-VGT，PROBA-V等。经验证，该数据集的总体精度在70%以上，当然精度会在不同的地区和覆被类型上存在差异。

This dataset is land cover data for the Qinghai-Tibet Plateau in 2012. The data is provided in raster TIFF format with a spatial resolution of 300 meters, and encompasses 22 major land cover categories including cropland, forestland, grassland, water bodies, urban land and others. It can be applied to geographic background research on the interactive stress between urbanization and the ecological environment on the Qinghai-Tibet Plateau. This dataset originates from the land cover data products generated by the ESA CCI-LC project. It adopts the WGS84 geographic coordinate system and includes 22 major land cover categories. The production of this dataset integrates multiple satellite data resources, such as MERIS FR/RR, AVHRR, SPOT-VGT, PROBA-V and other datasets. Verified results indicate that the overall accuracy of this dataset is above 70%, though the accuracy varies across different regions and land cover types.
