Data Set ID:

SMAPVEX12 Vegetation Water Content Map, Version 1

The Vegetation Water Content (VWC) Map for the Soil Moisture Active Passive Validation Experiment 2012 (SMAPVEX12) was derived by calculating Normalized Difference Water Index (NDWI) from SPOT and RapidEye satellite overpasses. In addition, samples from a range of vegetation types were used to compare VWC and NDVI to the satellite imagery.
