Determining the location of public safety personnel working in areas without a clear view of the sky, and therefore without access to reliable GPS, and providing mechanisms to create, access and share map (building and asset) data, is the focus of this project. The objectives are to accelerate availability of improved location accuracy, comprehensive map data sources and tools, and 3D visualization to meet an array of first responder use cases.
