Systems and methods for performing a risk management assessment of a property
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.
1. A computing system for generating an estimated floor area measurement, the computing system comprising:
one or more processor;
a non-transitory memory;
computer executable instructions for floor area measurement estimation stored on the non-transitory memory and that, when executed, cause the one or more processor to:
receive a first aerial image of a building having a roof, and a second aerial image of the building from at least one image file database, the first aerial image representing a top-down view of the top of the building, the second aerial image representing a view from a different angle than the top-down view of the building;
generate, a three-dimensional computer model of the roof, by analyzing the first aerial image and the second aerial image;
determine a total number of stories the building has using the second aerial image of the building;
determine, based at least in part on the determined total number of stories of the building and the three-dimensional computer model, an estimated floor area measurement of the building; and
output a floor area measurement report having floor area data thereon, the floor area data including the estimated floor area measurement.

7. The computing system of claim 6 , wherein the computer executable instructions for floor area measurement estimation, when executed, further cause the one or more processor to generate and deliver a floor area measurement estimate report that is annotated with a floor area measurement and one or more of: slope, area, and length of edges of at least some of a plurality of planar roof sections of the roof.
8. The computing system of claim 1 , wherein the computer executable instructions for floor area measurement estimation, when executed, further cause the one or more processor to deliver the floor area measurement estimate as part of a report including a plurality of floor area measurement estimates for a plurality of buildings in response to a request for a plurality of estimates from a single entity.
9. A non-transitory 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, the first aerial image being a top-down view of the building and the second aerial image being a view from a different angle than the top-down view such that 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;
determining a total number of stories the building has using the second aerial image of the building;
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;
