GEO DATA MANAGING METHOD APPARATUS AND PROGRAM BASED ON GEO KEY FOR EFFICIENCY IMPROVEMENT OF GEO DATA PROCESSING

摘要

A method performed by a computer, comprising the steps of: loading first spatial data, loading second spatial data, allocating a spatial key to each of the data items included in the first spatial data and the second spatial data The step of generating third spatial data by merging the first spatial data and the second spatial data, wherein the allocated spatial keys of the data items included in the first spatial data and the second spatial data coincide with each other. Disclosed is a spatial key-based spatial data management method for increasing spatial data processing efficiency, including merging data items.
