Korea is using Trimble's indoor mapping solution to map out its subway system for indoor wayfinding within 1m accuracy. Mobile app developers will be able ot ingrate the data and APIs starting next year.
The Trimble Indoor Mapping Solution (TIMMS) is a fusion of technologies for capturing spatial data of indoor location technologies. It provides both LiDAR and spherical video of a facility, enabling the creation of accurate, real-life representations (maps, models) of interior spaces and all of its contents; every object in the interior space, including stairs, and doors appear in the plan. The maps created are geo-referenced, meaning that the real world positions of each area of the building and its contents are known.
