First Claim
1. A computing system for generating an estimated floor area measurement, the computing system comprising:
- a memory;
a floor area measurement estimation module that is stored on the memory and that is configured, when executed, to;
receive roof edge measurements of a building having a roof;
generate, based at least in part on the received roof edge measurements, an estimated floor area measurement of the building;
adjust the estimated floor area measurement of the building to obtain adjusted roof edge measurements by at least one of;
subtract an amount from one or more of the roof edge measurements corresponding to an estimated roof overhang over one or more walls of the building;
subtract an amount from one or more of the adjusted roof edge measurements corresponding to an estimated wall width; and
subtract floor area spaces of the building that are not to be included in the estimated floor area measurement of the building, the floor area spaces of the building that are not to be included being received by the system; and
output a floor area measurement report having floor area data thereon.

Abstract
A system generates an estimated floor area measurement of a building based on the calculated estimated total roof area of the roof of the building. This is based on a correlation between the size of the building roof and the size of the building. Typically, the floor area of a single full floor of the building is roughly the size of the roof of the building if the roof were flat with no slope. This in effect is turning the roof into a floor to generate estimated floor area. With additional adjustments to area measurements to account for multiple floors, roof overhang, wall width, internal building features such as walls and staircases, and/or obstructed views of the building in the aerial image(s), etc., an even more accurate floor area estimation may be generated.

17. A computer-implemented method for generating an estimated floor area measurement, the method comprising:
-
calculating roof edge measurements of a roof of a building with each section of the roof being set to a slope of zero, without regard to an actual slope of each section of the roof; using the roof edge measurements to calculate an estimated total roof area of the roof with the slope of each section of the roof being set to zero; generating the estimated floor area measurement based on the calculated estimated total roof area of the roof, with the slope of each roof section set to zero, by at least one of; receiving information pertaining to how many stories the building has and about one or more sections of the roof below which one or more of the stories laterally extends, and generating the estimated floor area measurement based on a total area of the one or more sections of the roof under which the one or more of the stories laterally extends and based on the estimated total roof area of the roof; and receiving information pertaining to floor area spaces of the building that are not to be included in the estimated floor area measurement of the building, and generating the estimated floor area measurement based on an area corresponding to an extent to which the spaces extend under the roof. - View Dependent Claims (29, 30)

20. A computer-readable medium whose contents enable a computing system to generate an estimated floor area measurement, by performing a method comprising:
-
receiving a first and a second aerial image of a building having a roof, each of the aerial images providing a different view of the roof of the building; correlating the first aerial image with the second aerial image; generating, based at least in part on the correlation between the first and second aerial images, a three-dimensional model of the roof that includes a plurality of planar roof sections that each have a corresponding slope, area, and edges; generating an adjusted roof model by adjusting a slope of the planar roof sections in the three dimensional model of the roof to substantially zero; obtaining an estimated total roof area measurement based on the adjusted model; generating, based at least in part on the estimated total roof area measurement, an estimated floor area measurement of the building; and
adjusting the estimated floor area measurement of the building to obtain adjusted roof edge measurements by at least one of;subtracting an amount from one or more of the roof edge measurements corresponding to an estimated roof overhang over one or more walls of the building;
subtracting an amount from one or more of the adjusted roof edge measurements corresponding to an estimated wall width; and
subtracting floor area spaces of the building that are not to be included in the estimated floor area measurement of the building, the floor area spaces of the building that are not to be included being received by the system. - View Dependent Claims (21, 22, 31, 32)
