Remote sensing practice · France
GroundSense sources satellite imagery from any orbit, processes it into answers you can act on, and supervises the Earth observation projects that depend on it — for farms, forests, insurers, engineers and public bodies.
True colour (bands 4·3·2): what your eye would see from orbit — ripe wheat, green maize, sunflowers and a village of tiled roofs.
Services
Take one service or all three. Most projects start with a question, not a data order, so we begin there.
We search the archives and task new captures across optical, radar and thermal missions. You get a side-by-side comparison of cost, resolution, revisit and cloud risk before anything is ordered.
Raw scenes become analysis-ready layers, then answers. Each step is documented so your team can reproduce or audit it.
An independent eye on your Earth observation project, whether the work is done by us, by a provider or by your own team.
Data sources
Sometimes the answer is free Copernicus data refreshed every few days. Sometimes it takes a 30 cm tasking over a single site. Here are the sources we work with most, including the Chinese very high resolution constellations for wide-area 50 cm coverage and stereo.
| Source | Sensor | Ground resolution | Revisit | Access |
|---|---|---|---|---|
| Sentinel-2 Copernicus | Multispectral, 13 bands | 10 m | 5 days | Open |
| Sentinel-1 Copernicus | C-band radar (SAR) | 5 × 20 m | 6–12 days | Open |
| Landsat 8 & 9 USGS · NASA | Multispectral + thermal | 30 m | 8 days | Open |
| PlanetScope Planet | Multispectral, 8 bands | ≈ 3 m | Daily | Commercial |
| Pléiades Neo, WorldView & others | Very high resolution optical | 0.3–0.5 m | On-demand tasking | Commercial |
| ICEYE, Capella, Umbra | X-band radar, day & night | 0.25–3 m | On-demand tasking | Commercial |
| BD ORTHO® & LiDAR HD IGN, France | Aerial orthophotos & lidar | 20 cm · ≥ 10 pts/m² | National programme | Open |
| Drone & airborne | When orbit can’t resolve it | ≈ 2–5 cm | On request | Contracted |
| Chinese very high resolution optical | ||||
| SuperLens China | VHR optical, stereo & tri-stereo | 30 cm · 15 cm SR | Archive · on-demand tasking | Commercial |
| EarthScanner China | Wide-swath VHR optical, 150 km swath | 50 cm | Most countries in a few days | Commercial |
| MS8 EarthScanner China | Wide-swath VHR optical, 136 km swath | 50 cm | Archive · on-demand tasking | Commercial |
| GF-7 Gaofen-7 · China | Stereo pairs for 3D (DSM / DTM) | 65 cm | Archive | Commercial |
| DailyVision China | High-revisit VHR optical | 75 cm | High revisit · on-demand tasking | Commercial |
| Gaofen-2 GF-2 · China | VHR optical | 80 cm | Archive | Commercial |
These are nominal values. Actual revisit depends on latitude, viewing angle and cloud cover, and we’ll give you a realistic capture window for your site.
Chinese VHR scenes are delivered as L1 bundles (panchromatic + multispectral). We orthorectify, pansharpen and mosaic them, and build DSM / DTM from GF-7 and SuperLens stereo. “SR” is a super-resolution product derived from the 30 cm imagery, not a native resolution.

Method
Five stages, from the first call to follow-up. Supervision-only projects plug into whichever stage you’re at.
We pin down the decision the imagery supports, your area and period of interest, the accuracy you need and your budget.
We compare sensors, search the archives or plan new tasking, and agree licences before anything is ordered.
We correct, analyse, and validate against ground truth or reference data wherever it exists.
You get files in your formats and projection, plus a plain-language report of what the data does and doesn’t say.
Where needed, we stay on for monitoring, quality control and follow-up acquisitions.
We recommend on merit, per project. The right answer can be open data or a premium tasking, and we tell you which before you spend.
Every delivery states its method, the accuracy you can expect, and the limits of what the data can tell you.
We work in French and English, know the French public references (IGN, Theia, Copernicus), and can host data in the EU on request.
Platform In development
We’re turning our processing chains into subscription products for companies with EU reporting obligations. Each delivery comes with a traceable, verifiable evidence file.
EUDR · Regulation (EU) 2023/1115
Deforestation checks on your supply plots against the EUDR cutoff of 31 December 2020, using Sentinel-2 time series. Delivered as a report, GeoJSON and due-diligence data.
EU Taxonomy · CSRD ESRS E3
All-weather flood mapping of your sites from Sentinel-1 radar, with impact reports for physical-risk disclosure and alerts after an event.
