Abstract: Methods and systems for generating geometric models of buildings with from multiview imagery are provided. An example method involves establishing a three-dimensional coordinate space for the multiview imagery, displaying, through an annotation platform, first and second images of the multiview imagery depicting the building from different points of view, providing, through the annotation platform, functionality for a user to provide user input comprising instructions that annotate the first and second images with at least two adjacent building sections of the building having roofs at different heights, and reconstructing, based on the user input received through the annotation platform, a geometric model comprising at least the two adjacent building sections.

Abstract: Methods and systems for enhancing elevation models with landcover feature data are provided. An example method involves accessing imagery covering an area of interest that contains an above-ground feature, generating, a digital surface model of the area of interest, extracting three-dimensional landcover feature data representing the above-ground feature that contains one or more actual ground-level points at the base of the above-ground feature, and generating a digital terrain model from the digital surface model at least in part by removing the above-ground feature from the digital surface model and filling at least some of the removed area with one or more of the actual ground-level points from the three-dimensional landcover feature data.

Abstract: Methods and systems for generating geometric models of buildings with complex roof geometry from multiview imagery are provided. An example method involves establishing a three-dimensional coordinate space for the multiview imagery, and displaying, through an annotation platform, first and second images of the multiview imagery depicting the pitched roof from different points of view. The method further involves receiving, through the annotation platform, user input annotating the first and second images with a plurality of roof elements defining a three-dimensional structure of the pitched roof, and reconstructing, based on the user input received through the annotation platform, a geometric model representing the three-dimensional structure of the pitched roof situated in the three-dimensional coordinate space.
