What changes can I check?
Scenes from different times are compared on the same basis and the differences are marked on the map.
Agriculture & forestry
For agriculture and forestry, StellarHub compares imagery from each period on the same footing to show how farmland and forests change.
If this is your challenge
Farmland and forests look different every season, so comparing them on the same basis means many trips on the ground. It is also hard to decide which area to look at first.
How StellarHub solves it
Collect scenes by season through scheduled monitoring, compare them on the same basis, and let AI analysis find what changed. You can start with the areas that changed most.
Data used
Optical satellite imagery is the main source. In cloudy seasons you can consider SAR imagery alongside it, and you can upload your organization's shape data to review by area.
What you receive
You receive a change map for checking crop conditions and forest status, and you can export maps and results as a report to share.
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 farmland or forest area you want to review on the map.
Collect scenes by season
Receive or buy scenes each season to build up imagery of the same area.
Find what changed
AI analysis compares scenes from different times on the same basis and finds the differences.
Inspect and report
Use the change map to check crop conditions and forest status, and compile a report.
Changes it looks at
It looks at changes across wide areas that vary by season, such as crop conditions and forest status.
Farmland and forests cover wide areas and look different each season, so scenes must be compared on the same basis to tell real change from seasonal difference. Scenes from different times are gathered and compared on the same basis.
Checking the areas that changed most first makes it easier to set the order of field inspections, and results can be exported as a report to share with your colleagues.
What it mostly looks at
- Changes in crop conditions on farmland
- Changes in forest status
- Observation in cloudy seasons
How the results are used
The change map helps with crop checks, forest inspections, and planning your site visits across wide areas.
When the areas that changed within a wide region are marked, you can decide where to check first without visiting everything. Results compared on the same basis accumulate each time the season changes.
Typical uses
- Crop checks and site visit planning
- Inspecting changes in forest status
- Reports that gather results by season

Frequently asked questions
Can I receive imagery each season?
Yes. Schedule monitoring captures and imagery of the same area is captured and delivered on a recurring basis each season.
What about cloudy seasons?
SAR satellite imagery, which is less affected by clouds, can be considered alongside optical imagery.
Can I use my own area boundaries?
Yes. Shape data your organization owns can be uploaded so you can review the imagery by area.
Can it tell seasonal change from real change?
Scenes from different times are compared on the same basis to find the places that actually changed.
