Attorney, Agent or Firm: Frommer Lawrence & Haug LLP, Frommer; William S., Kessler; Gordon

The present invention relates to the field of geographic information systems (GIS). The invention presents an apparatus and a method for automatic managing a database (1) of geolocation information and for providing this information to geoinformation systems of for example wireless communication systems. According to the present invention an automatic search agent is provided effecting the following steps for managing the database (1): searching (4) nodes of a network, detecting (13), if geographical position information and associate information of a location is present at the searched node, retrieving the geographical position information and the associated information of the location present at the node of the network, and automatically entering the acquired geographical position information and associated information to the geographic information database (1).

DETAILED DESCRIPTION What is claimed is: 1.
Method for automatically managing a geographic information database, the geographic information database containing at least a geographical position information of a location and an associated information representing at least one feature of the location, comprising the steps of: searching nodes of a network periodically to update the geographical positional information and the associated information, detecting, if the geographical position information and the associated information of a location is present in a document at a searched node of said network, retrieving the document containing the geographical position information and the associated information of the location present at said searched node of said network, parsing the document to acquire the geographical position information and the associated information, automatically storing the acquired geographical position information, associated information and a pointer to the document in the geographic information database, and periodically rechecking the document at the searched node of a network for changes in the geographical position information and associated information.
2.
Method according to claim 1, characterized in that the searching (4), detecting (13), retrieving and entering step is conducted by one or a plurality of automatic search agents (4).
3.
Method according to claim 1, characterized in that the geographical position information contains the longitude/latitude information of a location.
4.
Method according to claim 3, characterized in that geographical position information present at a node of the network in an other format than longitude/latitude information is automatically converted into a longitude/latitude information format.
5.
Method according to claim 1, characterized in that one of the features of a location stored in the database is a link to a web page (8).
6.
Method according to claim 1, characterized in that one of the features of a location is a digital signature
