The present invention relates to a component-based open geographic information processing device, comprising a geographic information system composed of components consisting of a standard interface to access and utilize geographic data stored in heterogeneous databases in a single way, thereby reusable and mutual In order to provide an operable component-based open geographic information processing apparatus, in an open geographic information processing apparatus, a geographic data obtained by processing geographic data obtained by accessing a database storing geographic data is processed. Geographic data processing means for performing a spatial query on geographic data; Geographic object processing means for modeling geographic objects and performing spatial operations between the geographic objects; And spatial coordinate processing means for modeling a spatial coordinate system and processing coordinate transformation and projection between coordinate systems, and used for geographic information processing systems.
