Abstract
Systems and methods construct three-dimensional models of building structures with roofs by exploiting properties of the projection of a three-dimensional building structure onto the ground. This projection is a two-dimensional spatial graph, which can be constructed for example by a user or by an image recognition algorithm. The spatial graph is processed to recreate a three-dimensional model of the building structure.
