Painting the Growing Season in the Maize Triangle
NASA's NISAR satellite has provided a detailed visualization of agricultural activity in South Africa's Maize Triangle during the 2025-2026 growing season. The false-color composite reveals changes in crop types and vegetation, using radar data to highlight vegetated and unvegetated areas. This innovative technique allows scientists to monitor crop development and understand the impacts of irrigation and climate variability.
- ▪The visualization uses radar data to show how crop types changed during the Southern Hemisphere's growing season.
- ▪Green indicates vegetated areas, red represents unvegetated surfaces, and blue shows how rapidly vegetation changed.
- ▪NISAR's radar observations help scientists monitor agricultural productivity and land-use changes across large regions.
