Abstract: Systems and techniques for an indoor geospatial site builder engine are presented. A system can convert facility artifacts into geospatially-defined indoor space geometry and provides a rich user experience to visualize the facility's indoor space identifying important landmarks as well as providing controls to navigate the indoor space. The system can also provide the ability to record and change the location of fixed assets at run time as well as verify the location of fixed assets in indoor space in real-time. Similarly, geometries can be updated in real-time. The system further provides the geospatial capability to determine precise distances between assets, devices and other points of interest that are defined independently in separate geo-referenced maps that represent space in various facilities across the globe. The location validation component provides for validation of system device locations over time with the actual device location.
