According to popularization of the geographic information system (GIS), temporal data management has become very important. When GIS is used in daily work, the most frequently accessed data is the present data. Therefore, the access speed for the present data should not be lowered in spatiotemporal data management. Furthermore, the past data should also be able to be restored. This paper proposes a spatiotemporal data management method based on the geographic differential script file (GDSF) method. This method records changes in maps in the form of a graphical operation with a time print. When old data becomes necessary, the data is restored by applying the GDSF to the current map data. This paper describes a combination method of spatial data structure and the GDSF for expediting the excution of spatial retrieval.Read the full paper here: https://link.springer.com/chapter/10.1007/978-3-540-49121-7_48
