Abstract
Methods and systems for generating geometric models of buildings from multiview imagery are provided. An example method involves displaying at least a first image and a second image that depict the building from different points of view, providing functionality for a user to annotate, with reference to at least the first image and the second image, a three-dimensional structure of a first building section of the building having a polygonal outline of a first substantially horizontal roof structure situated at a first height, and a three-dimensional structure of a second building section of the building having a polygonal outline of a second substantially horizontal roof structure situated at a second height lower than the first height. The polygonal outline of the second substantially horizontal roof structure is annotated by selecting a point located directly on one of the side walls of the first building section.
