THE APPROACH
See inundation in context.
A flood map becomes useful when the observed water is connected to timing, landscape conditions and exposure. Our approach brings those layers together for review and planning.
Choose evidence that fits the conditions
Radar observations can help examine inundation when optical views are obscured by clouds. Image dates, rainfall history and a pre-event reference establish the context for comparison.
- Cloud-aware sensor selection
- Pre-event and event comparison
- Rainfall and observation-date context
Separate water from lookalikes
A radar response must be interpreted alongside terrain, permanent water and land cover. Seasonal wetness, smooth surfaces and image geometry can resemble or obscure inundation.
- Permanent-water and land-cover context
- Review of ambiguous areas
- Consistent treatment across dates
Connect mapped water with exposure
Mapped extent can be overlaid with agricultural areas, settlements and infrastructure to examine potential impact. Ground evidence and historical footprints help review the result.
- Flood extent and spatial exposure
- Independent evidence where available
- Visible source dates and limitations
What the workflow produces
- Dated flood-extent layers
- Exposure and susceptibility views
- Evidence and review notes
INTERPRETATION & LIMITS
Make the evidence inspectable.
A modelled susceptibility layer is not a live flood warning. Detection depends on acquisition timing, vegetation, urban geometry and the available validation evidence.
