黄土高原典型样区-安塞样区30米分辨率植被覆盖度数据集（2010年）

该数据集为2005年黄土高原典型样区-安塞样区植被覆盖度数据集，包含样区植被盖度、NDVI、SRTM　三个数据实体。样区设计为1个1:5万标准图幅（经差15′、纬差10′，面积大约410km2），地理坐标，分辨率为1 arc。空间分辨率为30米，数据为栅格格式，数据量11MB，投影为WGS_84。通过对下载的样区遥感影像数据进行预处理，进而计算该区域NDVI值，利用像元二分模型计算植被覆盖度。坐标转换为地理坐标后用精确范围切割成矩形数据块。

This dataset is the vegetation coverage dataset of the typical Ansai sample area on the Loess Plateau in 2005, which includes three data entities: vegetation coverage, NDVI, and SRTM of the sample area. The sample area is designed as one 1:50000 standard map sheet, with a longitude difference of 15 arcminutes, latitude difference of 10 arcminutes, and an area of approximately 410 km². It uses the geographic coordinate system, with an original resolution of 1 arcsecond and a final spatial resolution of 30 meters. The data is in raster format, with a data volume of 11 MB, and adopts the WGS_84 coordinate system. Preprocessing was performed on the downloaded remote sensing image data of the sample area, followed by the calculation of the regional NDVI value, and the vegetation coverage was estimated using the dimidiate pixel model. After converting the coordinates to the geographic coordinate system, the data was clipped into rectangular data blocks using precise spatial ranges.
