Systems and methods for estimation of building wall area

A computer-implemented method for generating estimated wall area measurements, the method comprising:

• generating, by a computer processor of a system for generating estimated wall area measurements, a three dimensional roof model of a roof of a building as part of a three dimensional building model of the building, the roof model having measurements of the roof including information regarding one or more edges of the roof;
• rendering, on a graphical user interface, an aerial image of the building showing an oblique view of the building;
• rendering, on the graphical user interface, the roof model overlaid on the roof of the building shown in the aerial image and aligned with the oblique view of the building;
• receiving one or more measurements indicative of one or more distances between one or more reference points on the roof and a ground surface on which the building rests, based at least in part on receipt of an indication from a user of one or more reference points selected in the aerial image rendered on the graphical user interface and indicative of one or more points on the ground surface;
• generating, by the computer processor, the ground surface in a corresponding area underneath the roof model based at least in part on the one or more measurements indicative of one or more distances between one or more reference points on the roof and the ground surface;
• generating, by the computer processor, a wall within the three dimensional building model by extending the wall in the three dimensional building model from along or near an edge of the roof represented by the three dimensional roof model toward the ground surface, the wall extending a distance until either intersecting a level of the ground surface, or intersecting another surface of the roof, according to the three dimensional roof model;
• rendering, on the graphical user interface, the building model overlaid on the building shown in the aerial image and aligned with the oblique view of the building;
• using, by the computer processor, dimensions of the wall generated in the three dimensional building model to determine an area of the wall;
• and
• outputting, by the computer processor of the system for generating estimated wall area measurements, a wall estimation report having the determined area of the wall thereon and wherein the generated wall estimation report is provided for repair and/or constructing a structure of the building.
