From orbit to roadside

From orbit to the ground,
we keep watch over infrastructure.

Drones, satellites and vehicle cameras combined with AI to streamline inspection and surveys of rivers and farmland.

SCROLL
Vision

Monitor wide areas
without going on site.

We capture changes in infrastructure and land across wide areas without adding manpower. With multiple “eyes” from orbit to the ground and AI, we support inspection and survey work for local governments and land managers.

Challenge

Too much ground,
too few people.

  • 01Shortage of inspectorsLimited staff cannot cover wide areas
  • 02Vast areas to coverLong river corridors and countless parcels make frequent checks impossible
  • 03Limits of visual inspectionMissed issues and difficulty prioritizing
  • 04Delayed awarenessIt takes too long to notice changes

Approach

From space to the ground,
the right eye for every target.

Spatial AI / Remote Sensing

Connecting satellites and UAVs
to the agricultural field.

Discover our Spatial AI platform integrating satellite imagery, UAVs, AI and GIS for agriculture — and our call for field trial partners in Spain and Cyprus.

Technology

Capturing change with
map data and AI.

All 12,978 farmland parcels in Nagoya are already in our PostGIS database. A two-stage detection pipeline built on YOLOv8 / RT-DETR / SAHI narrows down priority locations across wide areas.
