MOD44W.006 Terra Land Water Mask Derived From MODIS and SRTM Yearly Global 250m

  • The MOD44W V6 product provides a 250m resolution land/water mask derived from MODIS and SRTM data, distinguishing between land and water.

  • It utilizes a decision tree classifier and incorporates masks to mitigate issues caused by terrain, burn scars, clouds, and ice.

  • The dataset spans from 2000-01-01 to 2015-01-01 and is available through NASA LP DAAC at the USGS EROS Center.

  • It includes a 'water_mask' band indicating land or water and a 'water_mask_QA' band providing quality assurance information.

  • MODIS data and products acquired through the LP DAAC have no restrictions on subsequent use, sale, or redistribution.

Description

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.
