Description :
The AA. hypothesize that the spatial patterns of soil moisture control variations in vegetation production, and hence remotely sensed greenness. They investigate the relationship between soil moisture and a remotely sensed greeness, the normalized difference vegetation index (NDVI). Soil moisture was measured in the summer of 2000, and NDVI data were collected using an aerial digital multispectral camera system. Results indicate that the relationship between soil moisture and NDVI was significant in areas dominated by high-centered polygons and throughs, and where the general slope of the terrain promoted the redistribution of soil moisture.
