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.
