More Information
Summary:It is an object of the present invention to provide a scheme for distributing spatial information between information providers and information users.To achieve this object, the present invention creates a corresponding index for each spatial information. The index includes information related to a position included in spatial information, and data related to a storage location of the spatial information. This index also includes (1) a source ID for uniquely identifying spatial information; (2) coordinate translation values which are parameters used to correspond certain spatial information to other spatial information; and (3) when the spatial information including this index was created by referencing other spatial information, an underlay diagram specifying ID represented by the source ID possessed by the referenced spatial information, or the like.
