Flyover digital twin: a visibility study

A working twin built to answer a real engineering question: do 42 ten-metre lighting poles, spaced 40 metres apart, block the driver's view toward the horizon? We added a PTZ camera at pole height and two more observation points, east and west. First read — no meaningful obstruction; the road's gentle curve means even a small sideways shift of the camera clears it. The same world scales to a full twin with every pole and camera when needed.

Delos: heritage at scale, on your phone

A large set of geo-referenced 3D models of Delos, opening straight on a phone without strain — a hint at what the platform handles: city-, country-, even earth-scale data, visualised anywhere. Time and sun position are live, so the scene matches the real hour on site.

Projects

Research projects the platform grew out of and feeds into.

Mergin' Mode

Mergin' Mode was an EU-co-financed (ERDF) research project: demonstrate monuments by merging real and virtual in mixed reality, served as location-based experiences on mobile devices — built entirely on OGC geospatial standards and JavaScript APIs. It pairs an authoring tool with an end-user app, toward a “web of cultural data” that activates on a phone the way maps do.

FIREFLY

A research project with the “Athena” Research Center, FIREFLY targets intelligent, real-time modelling of the cognitive abilities of elderly people — pushing the technological groundwork that platforms like Klorad build on.
