Indexing system of space object for combination object of SOI and content

摘要

PURPOSE: A space information indexing system for a combined subject of space of interest (SOI) and the contents is provided to search subject information efficiently where contents information and SOI as a space subject are combined. CONSTITUTION: A position information extractor (210) sets up a minimum boundary area of a first SOI. The position information extractor calculates at least one center point coordinate of the minimum boundary area. A drawing number converter (220) maps the first SOI to a drawing number of a map including the center point coordinate. A spatial indexer (230) constitutes information for the mapped first SOI in a database type. When search for the first SOI is requested, the spatial indexer provides the result for a second SOI related with the first SOI.
