GeoSim

GeoSim’s custom technologies provide a pipeline for the collection, integration and validation of data for the creation of high-definition, naturalistic 3D city models for real-time exploration and interaction.
Key to the models’fidelity is the company’s proprietary Groundscan 3D city mapping platform, which fuses high-resolution scans and photos gathered aerially, at street level and in building interiors.
For ground-level scanning (photo below), the company employs a distinctive ‘stop-scan’ methodology using carefully chosen scanning points in each city street. They say this is up to ten times more accurate than moving-vehicle methodologies, and claim a spatial accuracy of 10cm for outdoor data, 5cm indoors.
