SYSTEM FOR INCREASING ACCURACY OF GEOCODE DATA

A mapping system uses aerial photographs to correct geocode data for street addresses. After entering an address, a street map is displayed along with an aerial photo, both of which indicate the street address location based on standard algorithms. The indicator on the aerial map can be moved to accurately align with the location of the entered street address, which corrects the geocode data, allowing further geographical analysis to be performed using the corrected geocode data. The corrected geocode data can be used to more accurately determine distances from the property at the street address to natural hazards such as, coastlines, earthquake faults and flood zones.
