Indexing system of spatial information for combined SOI object and content

摘要

Provided is an indexing system for retrieving SOI object by using map tile numbers including: a location data extractor configured to set a minimum bounding rectangle of SOI object and obtain at least one center point coordinate from the minimum bounding rectangle; a map tile converter configured to perform a spatial operation between at least one of the center point coordinate and map tile numbers, and to perform mapping of the SOI object onto map tile numbers if the center point coordinate exists on the map having map tile numbers; and an LBS indexer configured to store a plurality of SOI objects mapped onto corresponding map tile numbers in the form of an inverted file database.
