Map of the affected area
Georeferenced orthophoto produced with speed as the priority: the usable overview first, detail and model afterwards.
A flooded settlement: first the usable overview, detail afterwards.

Emergencies and civil protection
The state of things right after the event: flooding, landslides, collapse. A georeferenced map in hours, not days.
In the first hours after an event only one thing matters: knowing what happened and where. A flight over the affected area returns a georeferenced overview that overlays existing mapping, and from there the teams are directed.
Figures for this sector
- hours
- time from flight to the first usable overview map
- GeoTIFF
- format the authority's GIS opens with no conversion
- 1 cm/px
- detail when the particular matters more than the overview
What we do
Access and roads
Cut roads, bridges, fords and access points identified on current imagery, not on last year's map.
An embankment holding and the countryside under water: this way through, that way not.
Buildings and structures
Stripped roofs, cracks and collapse documented from above without sending anyone inside or onto the building.
After the whirlwind: opened roofs and downed trees, with nobody sent onto a roof.
Before and after
Where an earlier survey of the same area exists, the difference is immediate and measurable: areas, volumes, elevations.
Water over fields: where an earlier survey of the same area exists, the difference is immediate and measurable.
What you get
- Georeferenced overview orthophoto, delivered first
- Perimeters of the affected areas as shapefile or KML
- Close-up photographs of critical points, dated and with coordinates
- Terrain model and comparison with the previous survey, where available
Said up front
Over areas under emergency operations the airspace may be reserved for rescue aircraft: we fly only in coordination with whoever is managing the event, never on our own initiative.
