2020年中国区域TM-30m土地覆被分类样本数据集

利用TM影像和对应分类数据制作的土地覆盖分类样本数据。分类以切片方式存储，每一切片大小为256×256像素，7个波段，envi bsq格式。前6波段为影像，第7波段为分类数据，分类数据取值范围为0-8，0为无值区域，1-8分别代表（1）林地、（2）草地、（3）湿地、（4）水体、（5）耕地、（6）居民地、（7）裸地、（8）积雪等8类。分类样本覆盖全国，部分区域有多个时相的影像。

Land cover classification sample data produced using TM imagery and their corresponding classification data. All samples are stored as image slices, each with a size of 256×256 pixels and 7 spectral bands, saved in ENVI BSQ format. The first 6 bands are the original imagery, while the 7th band contains the classification data. The value range of the classification data is 0–8, where 0 denotes no-data regions, and values 1 through 8 correspond to 8 land cover categories respectively: (1) forest land, (2) grassland, (3) wetland, (4) water body, (5) cropland, (6) residential area, (7) bare land, and (8) snow cover. These classification samples cover the entire territory of China, and multiple temporal-phase images are available for some regions.
