System for increasing accuracy of geocode data
First Claim
1. A computer implemented method for interactively modifying geographical coordinates corresponding to a street address comprising:
- displaying a map representing a geographical area that includes an indication of the location of the street address;
displaying a geo-referenced image of the geographical area;
upon selection of a corrected location of the street address in the geo-referenced image, computing geographic co-ordinates of the corrected location;
redrawing the map based on the computed geographic co-ordinates; and
displaying an indication of the corrected location of the street address in the redrawn map at the computed geographic co-ordinates.

Abstract
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.

13. An apparatus for interactively modifying geographical coordinates corresponding to a street address comprising:
-
a screen that displays a map representing a geographical area that includes an indication of the location of the street address and a geo-referenced image of the geographical area;
upon selection of a corrected location of the street address in the geo-referenced image, a mapping routine which computes geographic co-ordinates of the corrected location, redraws the map based on the computed geographic co-ordinates and provides an indication of the corrected location of the street address in the map at the computed geographic co-ordinates. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. An apparatus for interactively modifying geographical coordinates corresponding to a street address comprising:
-
display means which displays a map representing of a geographical area that includes an indication of the location of the street address and a geo-referenced image of the geographical area;
upon selection of a corrected location of the street address in the geo-referenced image, means for computing geographic co-ordinates of the corrected location;
means for redrawing the map based on the computed geographic co-ordinates; and
means for displaying an indication of the corrected location of the street address in the map at the computed geographic co-ordinates.

26. A computer program product, for interactively modifying geographical coordinates corresponding to a street address, the computer program product comprising a computer usable medium having computer readable program code thereon, including program code which:
-
displays a map representing a geographical area that includes an indication of the location of the street address;
displays a geo-referenced image of the geographical area represented by the map;
upon selection of a corrected location of the street address in the geo-referenced image, computes geographic co-ordinates of the corrected location;
redraws the map based on the computed geographic co-ordinates; and
displays an indication of the corrected location of the street address in the map at the computed geographic co-ordinates.
