资源简介:
该数据集为2010年黄土高原典型样区-离石样区30米分辨率植被覆盖度数据集,包含样植被盖度、NDVI、SRTM 3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10MB,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 a 30-meter resolution vegetation coverage dataset of the typical Lishi sample area on the Loess Plateau in 2010. It contains three data entities: vegetation coverage, NDVI, and SRTM. The sample area is designed as a standard 1:50000 map sheet, with a longitude difference of 15′, latitude difference of 10′, and an area of approximately 410 km². It adopts geographic coordinates with a resolution of 1 arc, has a spatial resolution of 30 meters, is stored in raster format, with a total data volume of 10 MB, and uses the WGS_84 projection. Vegetation coverage and NDVI values of this area were calculated by preprocessing the downloaded remote sensing image data of the sample area, where vegetation coverage was further calculated using the dimidiate pixel model. After converting the coordinates to the geographic coordinate system, the data was cropped into rectangular data blocks based on precise spatial extents.
