3D City Models, GIS and Digital Twins for Municipalities
Running a city needs current, joined-up data. With up-to-date orthomosaics and a 3D city model, we build your building inventory and turn it into an urban GIS and digital twin platform.
What we do
- 3D city models
- Urban GIS and building inventory
- Digital twins
- Up-to-date orthomosaics
- Urban regeneration area mapping
- Unauthorised construction and change detection

Example analyses
Typical deliverables
3D terrain model
A 3D model of the ground and everything on it — surface model (DSM), bare-earth model (DTM), classified point cloud and textured mesh.
GeoTIFF (DSM/DTM), LAS/LAZ, OBJ, 3D TilesOrthomosaic
A georeferenced, distortion-corrected aerial image mosaic you can measure directly from.
GeoTIFF, ECW, JPEG 2000Progress monitoring
A dated record of surface change and construction progress, built by comparing surveys flown on different dates.
GeoTIFF, SHP, PDFTopographic survey
A layered, scaled digital survey to Turkish large-scale mapping standards, with spot heights, contours, buildings and site features.
DWG, DXF, NCZFAQs
What is a city model used for?
Zoning, visibility, shadow and density analysis, regeneration planning and public consultation.
Is building change detected automatically?
Yes — new and altered buildings are flagged by comparing successive orthomosaics and elevation models.
Other industries
Construction
On site, decisions come down to quantities and programme. We document every stage with measurable data — from pre-construction existing conditions, through each valuation period, to post-construction checks.
Mining
In mining, production, inventory and safety all come down to the ground. By surveying pits, benches and stockpiles regularly, we reconcile production by volume and keep track of slope geometry.
Energy (solar, wind, power lines)
In energy assets, a small fault can mean a big loss in output. We support the whole asset life cycle with spatial data — from site selection to post-commissioning thermal inspection.
Agriculture
No field yields evenly. We map crop health with multispectral imagery, flag problem areas early, and help you put inputs where they’re actually needed.
Infrastructure and transport
Long linear assets take days to survey on foot. We map road, canal and utility corridors in a single pass and inspect hard-to-reach structures such as bridges and viaducts up close.
Environment and forestry
Change in natural landscapes is slow but lasting. We monitor forest cover, erosion, water resources and land use with measurable data, giving environmental decisions a solid evidence base.
Disaster response and damage assessment
In the first hours after a disaster, an accurate, up-to-date map is critical. We map the affected area quickly, identify damage through before/after comparison, and provide a base for reconstruction.
