12. Apparatus for determining a requested map location, comprising: a database, which is arranged to hold a plurality of map objects having respective descriptors and loci; a user input device, which is arranged to accept a search query comprising one or more query terms that describe the requested map location; and a processor, which is arranged to identify in the database two or more matched map objects such that the respective descriptors of the matched map objects each match at least one of the query terms, to render the respective matched map objects onto a common grid using the loci, to identify grid cells overlapped by at least one of the rendered map objects, to assign respective scores to the identified grid cells based on a number of the matched map objects that overlap each of the identified grid cells, and to determine the requested map location responsively to the scores.

The apparatus according to claim 12 , wherein the processor is arranged to compare at least some of the map objects in the database to at least one of the query terms using an approximate string matching process so as to identify the two or more matched map objects.
