Flood hazard, damage and erosion maps built from terrain your engineers can check.
What keeps you up at night
The problems we are asked to solve most often in environment & floods.
- 01
Flood warning comes too late.There is no hazard map for the district.
- 02
Post-flood damage assessment takes weeks.
- 03
Rivers and drains are encroached; flow paths are blocked.
- 04
Erosion and riverbank loss go unmeasured.
- 05
Rainfall has shifted outside old design assumptions.
- 06
Relief funds are allocated on guesses, not mapped extents.
What we do about it
6 capabilities, one team, one coordinate system from field to dashboard.
- Watershed & Hydrological EngineeringCatchments, flow, runoff, flood risk and erosion.Know where water goes before you build in its way.
- Change Detection & MonitoringDisaster impact and environmental degradation.See every new structure, cut and encroachment between two dates.
- GeoAI & Satellite IntelligenceFlood extent from satellite imagery.Know what changed on your land, and where, without sending a team.
- LiDAR & 3D ScanningBare-earth DTM for the flood model.The ground under the trees, measured.
- Drone Survey OperationsRapid-response orthomosaics.A current, measurable picture of your site, flown on your schedule.
- Intelligent GIS DashboardsA live executive panel.Every layer, every date, in one panel your team can use.

≤10 cm
vertical RMSE for USGS 3DEP Quality Level 1 lidar
QL1 also requires at least 8 pulses/m² and nominal spacing of 0.35 m or less. A published standard, not a Spyder guarantee.
0.11 m
ground-model RMSE under medium vegetation: UAV laser scan vs photogrammetry
Vegetation taller than 60 cm. Laser scanning reached the ground where photos could not.
