1. A method for generating a building model, comprising:
collecting sensor data from a mobile tracking device traversing a building structure;
generating at least one connector representing a path of the mobile tracking device, wherein each connector comprises one or more connector polygons representing a structural feature of the building structure and a plurality of connection points;
generating a routing graph comprising the at least one connector, and indicative of a route through a portion the building structure; and
combining a plurality of routing graphs to generate a building model.
