1. A method of providing location-based information comprising:

  • providing a map-to-scale database which may be used to generate a map-to-scale depiction of a geographic region and a plurality of physical features therein with geographic accuracy and scaling, the map-to-scale database further including location-related information, the location-related information being associated with a first set of locations within the geographic region, the location-related information comprising data related to the plurality of physical features located at or near each location of the first set of locations, the location-related information further comprising depicted location-related information that would be depicted within the map-to-scale depiction and non-depicted location-related information that would not be depicted within the map-to-scale depiction;

    providing a topological map not derived from the provided map-to-scale database, the topological map depicting a second set of locations, a subset of which are also included in the first set of locations for which the map-to-scale database includes location-related information associated therewith;

    receiving into a computing device a query for the location-related information from the map-to-scale database for a particular location within the subset of the second set of locations depicted by the topological map;

    determining, based on the particular location specified by the received query, the location in the first set of locations corresponding thereto;

    accessing, by the computing device, the location-related information in the provided map-to-scale database associated with the determined location, the accessed location-related information including both depicted and non-depicted location-related information; and

    displaying, by the computing device, the accessed location-related information with respect to the particular location specified by the received query in the provided topological map.
