US 8,542,884 B1 · Systems and methods for flood area change detection

Abstract

In various embodiments, old flood maps may be compared to new flood maps to determine which areas of the flood map have changed. These changed areas may be correlated against geographic area descriptions that are within changed areas of the flood map. The changed areas may also be analyzed to determine whether each area has had a change in status (e.g., from a high risk flood zone to a non-high risk flood zone or vice versa) or a change in zone within a status (e.g., from one flood zone to another flood zone). The information on type of change (or no change) may be used to populate a database that includes geographic area description identifiers. In some embodiments, detection of certain types of changes may initiate a manual comparison of the old and new flood maps to verify the change.

Dependent claims

A method, comprising:

comparing, by a processor a first flood map to an updated second flood map, said first flood map and said updated second flood map each including flood zones and non-flood zones;
and creating, by a processor a third flood map, wherein the third flood map includes one or more demarcated areas based on the comparison of the first flood map to the updated second flood map, and wherein the one or more demarcated marking areas comprises a change designator indicating a change in risk level status of the first flood map to the updated second flood map and another designator indicating a change in zone of at least one area from the first flood map to the updated second flood map, wherein both designators are derived from the comparison of the first flood map to the updated second flood map.

Dependencies are inferred from the claim text.
