Abstract: A computer-implemented method for generating wall, window, and door reports. In one embodiment, an application may present a 3D mesh of a structure to an analyst. The application may also display 2D images of the structure for reference. The application may overlay a roof model on the 3D structure mesh. The analyst may begin by using a ground tool and then clicking a location on the 3D mesh. The application may then drop walls down from at or near the roof's outer edges to lower roof facets or to the clicked mesh elevation. The analyst may then use move, delete, and wall tools to adjust the walls. The analyst may then use window, door, and hole tools to draw openings. When the analyst finishes, the application may generate a report. The report may include multiple structure renderings with wall, window, and door labels plus length, perimeter, and area measurements.

Abstract: A computer-implemented method for identifying property changes by analyzing differences between old and new imagery. In one embodiment, an administrator begins by creating a project with links to old and new imagery and uploading a file with parcel boundaries. The application may then divide the project into smaller batches and then automatically classify each batch. Analysts may then review these batches and reject those that are insufficiently accurate. For rejected batches, analysts may manually classify the parcels. Analysts may then review these batches again. In one embodiment, once all batches are accepted, the project may be marked as complete and suitable reports may be generated and sent. These reports may include a customer report which may include overall project statistics, a breakdown of changes by type, a heatmap showing which areas are changing fastest, and/or an estimated tax impact of the identified changes.
