System and method for providing accurate local maps for a central service
View Patent ↗A system and method that provides economical and accurate data for a selected area (jurisdiction) from a centralized location by generating a base-line map from commercially available information and distributing portions of this map to local jurisdictions. Inaccuracies and other information only available locally are stored in a local database. Periodically these databases are uploaded to a central location and reconciled with the base line map. Advantageously, such reconciliation may include a rules based reconciliation wherein the geo-coordinates from the commercial vendors are used and applied to the local data. A new base line map is then generated and distributed back to the local user. In this manner, the local user has an accurate yet economical map.

determining local geographical data that is distinct from the first data and associated with the geographic location for the first map;
determining second geo-coordinates of the local geographical data for inclusion on said first map;
storing the local geographical data in the storage component;
performing a rules-based comparison of the first geo-coordinates with the second geo-coordinates;
receiving second data, that comprises the local geographic data, from the storage component in response to a second request that comprises second location information that is associated with the geographic location; and
generating a second map, that comprises the local geographic data and the representation of the geographic location, based on the second data.

receiving first data from a storage component in response to a first request that comprises the geo-coordinates of the first user located near the geographic location;
wherein the step of receiving the second data, that comprises the local geographic data, from the storage component in response to the second request that comprises the second location information that is associated with the geographic location comprises the step of:
receiving second data, that comprises the local geographic data, from the storage component in response to a second request that comprises the geo-coordinates of the second user located near the geographic location.
12. The method of claim 11 , wherein the first user and/or the second user comprise one or more of police, fire, and/or emergency workers, wherein the step of receiving the first data from the storage component in response to the first request that comprises the geo-coordinates of the first user located near the geographic location comprises the step of:
receiving first data from the storage component in response to a first request that comprises the geo-coordinates of a one or more of police, fire, and/or emergency workers located near the geographic location;
wherein the step of receiving the second data, that comprises the local geographic data, from the storage component in response to the second request that comprises the geo-coordinates of the second user located near the geographic location comprises the step of:
receiving second data from the storage component in response to a second request that comprises the geo-coordinates of one or more of police, fire, and/or emergency workers located near the geographic location.
13. The method of claim 1 , further comprising the steps of: receiving an upload package that comprises the local geographical data for one or more maps from a regional server;
storing the local geographical data in the storage component;
updating a national map for the one or more maps with the local geographical data of the upload package to create an updated national map; and
downloading the updated national map to one or more regional servers.
14. The method of claim 13 , wherein the upload package of data comprises local geographical data for the one or more maps, wherein the step of updating the national map for the one or more maps with the data of the upload package to create the updated national map comprises the step of:
performing a rules-based comparison of the local geographical data with commercial data for the one or more maps; and
updating the national map with the local geographical data.
15. The method of claim 1 , wherein the local geographical data comprises one or more of a local name, land mark, road, road sign, and/or map feature.
16. The method of claim 15 , wherein the local geographical data comprises geo-coordinates for the one or more of the local name, land mark, road, road sign, and/or map feature.
17. An apparatus for generating maps comprising:
means for receiving first data from a storage component in response to a first request that comprises first location information associated with a geographic location, wherein the first data comprises first geo-coordinates;
