2000-2020年一带一路1km MODIS植被状况数据

2000-2020年一带一路植被状况数据集，包含NDVI/EVI，NPP两个数据产品。NDIV/EVI数据产品每年2期（1月份和7月份各1期），空间分辨率为1km，地理坐标为WGS_1984，每条数据包括两个波段（波段1为NDVI值，NDVI= DN×0.0001，填充值为-3000；第二个波段是EVI值，EVI= DN×0.0001，填充值：-3000）。NPP数据产品每年1期，空间分辨率为500m，地理坐标为WGS_1984，每条数据包含一个波段，代表像素所在位置的NPP，NPP= DN×0.0001，数据有效值范围为-30000–32700，填充值为-32767。

Belt and Road Initiative Vegetation Status Dataset (2000–2020) contains two data products: NDVI/EVI and NPP.
For the NDVI/EVI data product, there are 2 temporal samples per year (one in January and one in July), with a spatial resolution of 1 km and geographic coordinate system WGS_1984. Each dataset includes two bands: Band 1 corresponds to NDVI values, where NDVI = DN × 0.0001, with a fill value of -3000; Band 2 corresponds to EVI values, where EVI = DN × 0.0001, with a fill value of -3000.
For the NPP data product, there is 1 temporal sample per year, with a spatial resolution of 500 m and geographic coordinate system WGS_1984. Each dataset contains one band representing the NPP value of the corresponding pixel, where NPP = DN × 0.0001. The valid value range of the data is -30000 to 32700, and the fill value is -32767.
