Property Quest
공공데이터포털
DCPropertyQuest has been developed by the District of Columbia Office of Planning as an easy way to view a wide range of site-related information, especially information on historic resources. This site uses ArcGIS Server from ESRI to supply spatial data for mapping and analysis, and Adobe’s Flex technology to display it. When you enter an address, it looks it up in DC’s Master Address Repository to find that specific location. It then searches there for the matching lot, and searches again for historic resources that might be present on that lot.
