Google Earth Engine ——MOD44W V6陆地/水面掩膜250米产品是使用用MODIS数据

The MOD44W V6 land/water mask 250m product is derived using a decision tree classifier trained with MODIS data and validated with the MOD44W V5 product. A series of masks are applied to address known issues caused by terrain shadow, burn scars, cloudiness, or ice cover in oceans.

MOD44W V6陆地/水面掩膜250米产品是使用用MODIS数据训练的决策树分类器得出的，并通过MOD44W V5产品进行验证。一系列的掩膜被应用于解决由地形阴影、烧伤疤痕、云量或海洋中的冰盖造成的已知问题。
