Ground-Truth Enhanced Satellite Intelligence

Fusing NASA satellite imagery with IoT sensor ground truth to deliver higher-accuracy soil moisture, vegetation, and precipitation analytics. Ground-truth sensors fill the gaps that cloud cover, revisit cycles, and spatial resolution leave in satellite-only estimates.
