What kinds of change can it find?
It compares imagery of the same area across dates and marks the places that look different on the map for your review.
Land & urban change monitoring
Land and urban change monitoring compares satellite imagery of the same area on a regular cycle to find what has changed.
If this is your challenge
Cities expand and land use shifts quickly, yet checking on site takes time and people. Without knowing what changed, it is hard to decide where to inspect first.
How StellarHub solves it
Receive the same area through scheduled monitoring captures or buy scenes, and AI analysis compares them with earlier imagery to find and mark what changed. You can also be notified when a change passes your threshold.
Data used
Optical satellite imagery is the main source. When clouds get in the way, SAR imagery can be considered alongside it, and shape data your organization owns can be uploaded for the same analyses.
What you receive
Changes are marked on the map and can be exported as a report, so you can pick the places to check first and set the order of field visits.
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.
Set the area of interest
Draw the city or development area you want to watch on the map.
Schedule monitoring captures
Schedule recurring captures of the area, or buy the scenes you need.
Find what changed
AI analysis compares the scenes with earlier ones and marks what is different.
Use it in reports
Export the change map as a report for inspections and briefings.
Changes it looks for
It looks at changes over time such as urban expansion, new development areas, and land-use change.
Development and land-use change across a wide area become visible at a glance when scenes are compared on the same basis, without visiting every site. Receiving imagery on a monitoring cycle also shows how fast things change.
Changes are marked on the map to help you pick the places to check first. Because the comparison uses the same basis, the results make a good evidence for reports.
What it mostly looks at
- Newly built facilities and expanded development areas
- Places where land use changed
- Places where a change passed your threshold
How the results are used
The change map is used to choose what to inspect and to back up your reports with evidence.
Once changes are marked on the map, you can decide where to look first before going on site. Because the comparison uses the same basis, reports from different periods are easy to read one after another.
Typical uses
- Choosing what to inspect on site
- Evidence for development status reports
- Deciding the next monitoring cycle

Frequently asked questions
Can I receive imagery on a regular cycle?
Yes. Schedule monitoring captures and imagery of the same area is captured and delivered on a recurring basis for you.
What happens when clouds block the view?
SAR satellite imagery, which can observe through clouds, can be used alongside optical imagery.
Can I turn the results into a report?
Yes. Change results and map views can be gathered into a report and exported to share with your team or your management.
What do you compare to find changes?
Scenes of the same area are compared with earlier imagery to find the places that look different.
