Disaster & water resources

For disasters and water resources, StellarHub compares imagery from right after an event with usual imagery to see the damage and changes.

If this is your challenge

When floods or droughts hit, you need to know the extent of damage as fast as possible, but access on the ground is hard and clouds are common. Rivers and reservoirs also need steady attention in normal times.

How StellarHub solves it

Order a new capture (tasking) right after a disaster, and AI analysis compares it with usual imagery to single out the affected area. Rivers and reservoirs are followed through scheduled monitoring captures.

Data used

Optical and SAR satellite imagery are used together. SAR imagery can observe the surface even through clouds, which helps right after a disaster.

What you receive

Affected areas and changes in water appear on the map for situation reports. Changes that pass your threshold also reach you as notifications.

How it works

How it runs

Set the area of interest, receive imagery, find what changed with AI analysis, and put the results to work.

  1. Set the area of interest

    Draw rivers, reservoirs, and areas at risk on the map.

  2. Prepare baseline imagery

    Buy usual scenes or build them up through scheduled monitoring.

  3. Capture right after the event

    Order a new capture when a disaster hits, and use SAR imagery if clouds block the view.

  4. Check the affected area

    AI analysis compares before and after scenes, marks the affected area, and feeds your reports.

Situations where it helps

It looks at the extent of damage from disasters such as floods and droughts, together with everyday changes in rivers and reservoirs.

When a disaster hits, many places are hard to reach, so the extent of damage is hard to grasp. Comparing imagery captured right after the event with usual imagery shows where things changed on the map.

In normal times you can follow rivers and reservoirs through scheduled monitoring, and be notified first when a change passes your threshold.

What it mostly looks at

  • Affected areas right after a disaster
  • Changes in water in rivers and reservoirs
  • Surface observation on cloudy days

How the results are used

The marked affected areas help with situation reports, and with deciding the order of response.

Right after a disaster, quick judgment is needed. When areas that look damaged are already marked on the map, it takes less time to decide where to check and respond first.

Typical uses

  • Situation awareness and reporting upward
  • Setting the order of on-site checks and response
  • Following changes in rivers and reservoirs

Frequently asked questions

Can I get imagery right after a disaster?

Yes. Order a new capture (tasking) so fresh imagery of the area is taken right after the event.

Can I see through heavy clouds?

SAR satellite imagery can observe the surface even when clouds are present, which makes it useful right after a disaster.

Can I follow normal conditions too?

Yes. Scheduled monitoring lets you follow rivers and reservoirs on a recurring basis, long before any disaster strikes.

How is the damage area shown?

Before and after scenes are compared, and the affected area is singled out and marked on the map for your reports.

Will I be notified when something passes the threshold?

Yes. A notification is sent first whenever a change passes the threshold you set, so nothing slips past you.
