Hitachi Software has developed a specialized service called HouseDiff to assist agencies to track building changes. Putting update satellite/aerial imagery and existing vector data together in our automatic change detection software, HouseDiff can even identify small changes like additions and new/removed buildings.

This service enables agencies to eliminate tedious manual inspections and also helps to identify changes quickly, efficiently and more economically. So you can update and complete the building data anytime.
