A false-color composite derived from NISAR data highlights vegetated areas (green), unvegetated surfaces (red), and how rapidly vegetated areas changed (blue) during the 2025-2026 growing season in an agricultural region of South Africa. Most pixels contain a mix of these colors, producing the visualization’s rich and varied color palette. Credit: Paul Siqueira (UMass Amherst) using data from the NISAR GCOV product, and prepared for NASA Earth Observatory by Michala Garrison Radar data from an agricultural area in South Africa, shown in a vivid color palette, reveal crop types and how they changed during the Southern Hemisphere's growing season. Along the Vetrivier (Vet River) in South Africa, a patchwork of circular and rectangular fields spreads across what is otherwise a semi-arid part of the Free State province. The water brings life to an array of crops, contributing to the agricultural productivity of the wider Maize Triangle .…
