Satellite data can provide observations across a wide area during wildfires, floods, storms and other events.
Those observations can help responders understand affected areas, track change and assess damage to infrastructure when ground access is limited.
Impact analysis normally requires both a baseline and a current observation. Optical imagery can be restricted by cloud, smoke or darkness, while radar and other sources may provide different forms of evidence that require specialist interpretation.
Response teams should know the capture time, covered area, processing status and confidence of each product. A map based on an earlier pass must not be presented as a live view of conditions on the ground.
Used with current local information, satellite data can support rescue planning, resource allocation and recovery. Arche Zero helps teams select suitable sources, match records from before and after an event, and keep the limits and timing of each output visible.
Set the requirements before choosing a source.
- The decision or task the data must support
- The geography, period and minimum spatial resolution
- The update frequency and acceptable delay
- The source, processing and licence details to retain
