What this means
The document discusses SANSA's analysis of the Cape Town floods using Sentinel-1 SAR imagery to map current surface water and model flood risk. It explains that flood extents and risk zones were analyzed by comparing May 2026 imagery with April 2026 conditions, identifying widespread flooding and vulnerable areas in low-lying, peri-urban, and informal settlements. The analysis provides quantitative figures on flooded extent and built-up areas, illustrating the role of Earth Observation in disaster response and planning.
