Satellite Imagery
Analyze multi-source overhead imagery
Satellite imagery is Nexma's overhead-observation capability — searching the global archive, tasking fresh captures, and analyzing multi-source imagery to see what changed, what moved, and what is at risk. Optical, SAR, and multispectral across every commercial provider, delivered straight into the world model and analyzed automatically. When the latest pass is weeks old and you need a current look, you command a new one instead of waiting.
It is the same operating system — DataStore, Jax, the SatelliteEngine for collection, and the InsightEngine for analysis — pointed at the planet.
What you can do
- Search the archive. Query the cross-provider catalog by area, date, sensor, resolution, and cloud cover, and price every option side by side.
- Task new captures. When the archive is not enough, commission a fresh capture over any area of interest and track it from tasked to delivered.
- Analyze automatically. Change detection, object classification, and terrain modeling run continuously on incoming imagery.
- Detect change over time. Time-series analysis over months or years tracks construction progress, encroachment, deforestation, subsidence, and buildup with calibrated confidence.
- Assess asset health. Monitor infrastructure across passes to surface degradation, encroachment, and risk before it becomes failure.
Core concepts
Imagery in Nexma is not a GeoTIFF you stitch into a separate tool. Every capture lands in the DataStore as a georeferenced layer, time-stamped, available to every view and every other capability the moment it arrives.
- Collection and analysis are one loop. SatelliteEngine runs the front half — search and task — and InsightEngine runs the back half — detect and compare. Deliveries flow from one to the other without leaving the platform.
- SAR sees through cloud and dark. Optical fails under weather and at night; synthetic-aperture radar does not. With both, weather never stops collection.
- History is built in. Because every capture persists with its timestamp, imagery over an area becomes a temporal record — not a one-off file — so change is a query, not a manual diff.
Searching finds imagery that already exists. Tasking commissions a capture that does not exist yet. The capability covers both, from one interface, across every provider.
How it works
You request a look at an area. The capture is delivered into the world model, and analysis runs on top of it — observe, decide, task, repeat.
1Need: a current assessment of an area the archive doesn't cover
2 1. Search query the cross-provider catalog (area · date · sensor · cloud)
3 2. Task commission a new capture; pick optical, SAR, or multispectral
4 3. Deliver write a georeferenced layer into the DataStore
5 4. Analyze InsightEngine runs detection + change against prior passes
6 5. Act flag encroachment, score asset health, or trigger a workflowOne catalog spans the commercial constellation — Maxar, Airbus, Planet, Capella, Umbra, and more — so you compare, price, and order without switching tools.
Discover, task, analyze
| Stage | What you get |
|---|---|
| Discover | Archive search by area, date, sensor, resolution, cloud cover; transparent per-scene pricing clipped to your AOI |
| Task | New collection over any AOI; optical, SAR, multispectral; full order tracking with live status and ETA |
| Analyze | Automated change detection, object classification, terrain modeling; time-series over months or years |
Example
A utility needs to confirm no third-party construction has encroached on a transmission corridor.
- Search the archive over the corridor; the most recent clear pass is six weeks old.
- Task a fresh optical capture, with a SAR backup in case of cloud, and track the order to delivery.
- The capture lands in the DataStore as a georeferenced layer beside the historical passes.
- InsightEngine compares the new pass against the corridor baseline and flags two new structures inside the easement.
- Each flag becomes a typed entity; an AgentEngine workflow opens an encroachment case and routes it to the field team.
Swap the area and intent and the same search-task-analyze loop serves agricultural assessment, disaster response, or military monitoring. Collection and analysis are generic; the meaning comes from what you point them at.
