The present invention offers a feature data management method which provides data indicating created time and destroyed time of geographic object for feature data, thereby increasing the speed and facilitating a search in time direction. By this method, for example, if the building C is built at time Ts and destroyed at time Te, created time Ts and destroyed time Te of geographic object C are registered in the feature data, whereby it can be managed by a database that the geographic object C existed only between times Ts and Te.

1. A geographic information data management method which handles as geographic information data including feature, coordinate, area and attribute information of geographic objects, and registers the geographic information data in a database for management, the geographic information data management
1. A geographic information data management method which handles as geographic information data including feature, coordinate, area and attribute information of geographic objects, and registers the geographic information data in a database for management, the geographic information data management method comprising the steps of: when any one of the feature, coordinate, area and attribute information is created, creating data of the feature, coordinate, area and attribute information is created, and storing a created time in the geographic information data thereof to register the geographic information data in said database; and when any one of the feature, coordinate, area and attribute information is destroyed, storing a destroyed time in geographic information data thereof stored in said database to register the geographic information data in said database. 2. A geographic information data management method according to claim 1, wherein the geographic information data is provided with an ID number, when a geographic information is replaced, the ID number of geographic information data before the replacement is stored in the data of the geographic information after the replacement as additional information of created time thereof and the ID number of the geographic information data after the replacement is stored in the data of the geographic information as additional information of destroyed time thereof, so that each geographic information data is registered in said database. 3. A geographic information data management method according to claim 1, wherein to a client system connected to said database through a network, geographic information data obtained in the past in the client system is transferred as the change differences of between said geographic information data obtained in the past and geographic information data at a specified time. 4. A geographic information data management method according to claim 1, which further comprises the steps of extracting geographic information data existing at a specified time from the database, the step of rebuilding a rebuilt database in which time data is excluded from the extracted geographic information data, and the step of retrieving data for the rebuilt database. 5. A geographic information data management method which handles as geographic information data including feature, coordinate, area and attribute information of geographic objects, and registers the geographic information data in a database for management, the geographic information data management method comprising, when any one of the feature, coordinate, area and attribute information changes, storing, in geographic information data, a change occurrence time, a changed attribute of the geographic information, and a change amount of the changed attribute, respectively as changed time, name of the changed attribute, and differential value of the changed attribute to register the geographic information data in said database. 6. A geographic information data management method according to claim 2, wherein a rotation angle, change of position, and enlargement ratio of the feature are parametrically set such that changes of the feature are represented by parameters.
