CHC Navigation has launched the CHCNAV CoMeta, professional desktop software that combines photogrammetry and native 3D Gaussian Splatting (3DGS) in a single processing environment.
The software transforms Unmanned Aerial Vehicle (UAV) and camera imagery with positioning and orientation data into georeferenced orthomosaics, Digital Surface Models (DSMs), textured 3D meshes, and photorealistic 3DGS models.
CoMeta supports professional workflows across surveying and mapping, engineering, real-scene 3D mapping, infrastructure digitalization, and digital twins. By combining photogrammetric processing and native 3DGS, it enables users to produce both measurement-oriented geospatial deliverables and realistic 3D scenes from the same source imagery.
A single aerial triangulation result within CoMeta can generate multiple professional outputs. Orthomosaics, DSMs, and textured meshes support surveying, GIS production, engineering documentation, and spatial analysis. Native 3DGS adds photorealistic visualization for digital twins, infrastructure visualization, real-scene 3D mapping, and immersive presentation.
For visually complex elements such as water surfaces, glass facades, vegetation, and thin structures, CoMeta’s 3DGS workflow can reduce manual model retouching time by more than 70% compared with the tested conventional mesh refinement workflow.
A single project within the environment can process more than 100,000 images, reducing the need to manually divide large datasets and merge separate results. Distributed cluster processing across 15 or more computing nodes further expands capacity for wide-area and high-volume mapping projects.
Automated batch processing and dual-engine computation accelerate aerial triangulation, orthomosaic generation, and 3D mesh reconstruction. In benchmark datasets, CoMeta completed end-to-end photogrammetry workflows approximately two to three times faster than the mainstream software configurations tested. This processing capacity supports large-area aerial mapping, river and corridor surveys, engineering surveys, and urban and rural 3D mapping projects.
CoMeta operates with imagery from various UAV and camera manufacturers rather than requiring a proprietary acquisition platform. Its built-in calibration database includes more than 400 camera profiles covering systems from DJI, Sony, Feima, RIY, Saier, and other manufacturers. Standard positioning and orientation data can be imported from different acquisition platforms, allowing users to process existing datasets and continue using established field equipment.
Processed results can be exported in commonly used formats including GeoTIFF, OBJ, PLY, OSGB, 3D Tiles, and LAS for integration with surveying, GIS, engineering, visualization, and digital twin software environments.
