Geospatial Baseline for Nuclear Site Investigation in Thrace, Türkiye
Approximately 2,000 km², 27 missions, about 70 airborne hours and nine QA blocks — a controlled geospatial baseline for complex site investigation.
A dependable geospatial baseline for a high-consequence strategic-site investigation
The survey formed the geospatial foundation for a wider technical investigation in Thrace. MapSoft's documented responsibility was precise and limited: capture, process and quality-control terrain and imagery data that multidisciplinary teams could use as a reliable spatial input layer.

The survey formed the geospatial-foundation layer of a wider technical investigation for a potential nuclear-energy site in Thrace. Multidisciplinary site-characterization teams require reliable terrain and imagery inputs, but those downstream studies are programme context. MapSoft's defensible objective was to capture, process and quality-control a large geospatial baseline, not to select the nuclear site or perform nuclear, geological, geotechnical, seismic, hydrological/coastal-hazard or environmental engineering.
The wider programme included multidisciplinary site-characterization work. MapSoft's documented role was limited to geospatial acquisition, processing and QA; site selection and nuclear, geological, geotechnical, seismic, coastal-hazard and environmental engineering were outside its scope.
Twenty-seven missions combined LiDAR and aerial imaging across a large coastal study area
The programme required simultaneous airborne LiDAR and imagery, repeated mission control, flight-permission coordination and a production structure that could keep every acquisition traceable from the aircraft to the final QC package.



Coordinate permits and local operational support
Acquire simultaneous imagery and LiDAR over 27 missions
Post-process GNSS/INS trajectory and generate SBET
Georeference, colourize and adjust LiDAR strips
Evaluate coverage, density and control by block
Produce the final QC evidence package
Mission-scale acquisition was converted into a nine-block production and QA system
The final QC structure grouped 27 acquisition missions into nine processing / quality-control blocks. This made trajectory, strip, coverage, density and vertical-control checks manageable across a study area of approximately 2,000 km².

Navigation, LiDAR and imagery were processed as one controlled geospatial chain
GNSS/INS trajectory processing, SBET generation, direct georeferencing, LiDAR colourization, strip adjustment and terrain-focused classification were handled as connected technical stages. Processing remained inside Türkiye under the project's data-localization restrictions.
The processing model had to respect data-localization and confidentiality constraints
Project data were not permitted to leave Türkiye. MapSoft therefore processed the acquired data in-country and maintained mission- and block-level traceability while working within the documented confidentiality framework.
Quality was demonstrated with measured residuals, strip comparison and density verification
The final QC package did not rely on a single acceptance number. It documented mission trajectories, relative strip consistency, vertical control, total density, ground density and area coverage by processing block.




Measured QA/QC. The final QC report documents designed-versus-realized mission review, GNSS/INS trajectory statistics, tie-plane strip adjustment, control-field vertical checks, one-metre total-density grids, 40 × 40 m ground-density grids and full coverage checks by block. Reported block mean height offsets range from −0.022 m to +0.003 m, height standard deviations from 0.009 m to 0.023 m and point-to-plane RMS from 0.030 m to 0.075 m. Processing remained in Türkiye under data-localization and confidentiality restrictions.
A controlled stack of imagery, LiDAR, terrain data and QA evidence
The project delivery connected raw airborne acquisition to georeferenced datasets and documented technical validation. MapSoft's scope covered airborne acquisition, initial processing, ground/bare-earth classification and QA; building/vegetation classification and final orthophoto production were delivered by the partner.

Technical reportA traceable spatial baseline for multidisciplinary technical investigation
MapSoft completed and formally handed over a traceable, quality-controlled airborne geospatial baseline for multidisciplinary site investigation. The result is a geospatial input layer; it is not evidence that MapSoft selected the nuclear site or performed downstream nuclear-safety or engineering studies.
0127 missions integrated into nine QA blocks
02Full-area coverage and density compliance documented by final QC
03Secure in-country processing under data-localization rules
04Reliable terrain/imaging baseline for multidisciplinary site investigation
Thrace demonstrates MapSoft's capacity for secure international large-area airborne mapping: multi-mission LiDAR and imagery acquisition, in-country processing, direct georeferencing, strip adjustment and evidence-led block-level QA. It also demonstrates disciplined scope separation in a high-consequence strategic-infrastructure context.
MapSoft can execute large international airborne programmes under operational and data-handling constraints — combining multi-mission acquisition, direct georeferencing, LiDAR adjustment and block-level QA into one defensible geospatial delivery chain.
