LiDAR Survey
Terrestrial, mobile and UAV LiDAR for corridors, city blocks and asset inventories.
A digital twin is worth building only if it can answer questions. Ours are semantic models: every building carries height, footprint area, floor count, use and parcel identifier, so you can query the model for shadow impact, rooftop solar potential, flood exposure by floor, or floor space index compliance across a ward.
Geometry comes from LiDAR and UAV capture, textures from oblique imagery, and the result is published in CityGML for archival and 3D Tiles for streaming to a browser, so it works in your GIS and in a public-facing viewer.
What you receive
- CityGML model at LOD 1 or LOD 2, LOD 3 for selected structures on request
- Textured mesh from UAV oblique imagery
- Streamable 3D Tiles tileset for web and Cesium delivery
- Building attribute table linked to parcel and property records
- Terrain surface integrated with the building model
- Analysis outputs on request — shadow, visibility, solar, flood exposure
