specific Embodiment approach 1

[0072] The specific embodiment one of the place name data expansion method in the electronic map of the present invention includes:

[0073] Step 110, determine the place name entity to be queried.

[0074] It may be determined according to the name of the place-name entity input by the user, that is, the place name.

[0075] Step 120, according to the place name entity to be queried, query the corresponding historical atlas in the electronic map database.

[0076] Wherein, the electronic map database is the same as the electronic map database mentioned in the specific implementation of the device for expanding place name data in the electronic map of the present invention, and will not be repeated here.

[0077] Step 130, according to the place-name entity to be queried, query records related to the place-name entity in the gazetteer database. This record is used to record the historical evolution information of the corresponding place name entity

[0078] Wherein, the gaz...

specific Embodiment approach 2

[0090] The second embodiment of the geographical name data extension method in the electronic map of the present invention includes:

[0091] Step 310, determine the place name entity to be queried and the time or time period.

[0092]It may be determined according to the time or time period input by the user and the name of the place name entity, that is, the place name.

[0093] In step 320, according to the time or time period, matching is performed in the electronic map database and the gazetteer database respectively, and relevant historical atlases and relevant records are searched.

[0094] Through time matching, the historical atlas corresponding to the time is found in the electronic map database, and the record corresponding to the time is found in the gazetteer database. As described in the foregoing specific implementation manner, each record in the gazetteer database records the relevant historical evolution information of a certain place-name entity.

Abstract

The invention provides an expansion method and an expansion device of place-name data in an electronic map. The expansion device comprises a first storing unit, a second storing unit, a matching module and an output device, wherein the first storing unit is used for storing a database of the electronic map, the second storing unit is used for storing the database of a place-name dictionary, the matching module is used for associating a historical atlas in the database of the electronic map with a record of corresponding place-name entity in the database of the place-name dictionary; and the output device is used for outputting the result of the matching module after the associating. By adopting the device or the method, the historical atlas in the database of the electronic map is associated with the historical development related to place-name entity recorded in the database of the place-name dictionary, and thereby a user can gain more spatiotemporal information and attribute information of the place-name entity in the historical development process; and the historical development of the place-name entity can be analyzed and inversed conveniently.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a geographic information system. Background technique [0002] With the increasing development of computers and networks, people are increasingly relying on electronic information systems for research on various types of knowledge. For example, use geographic information system to sort out a large amount of spatio-temporal information involved in various historical materials. However, some existing geographic information systems, such as the spatio-temporal data model in GIS technology and the design of place name database, provide the possibility for the informatization of historical geographic evolution process. [0003] At the same time, because the data of historical place names is always changing with the evolution of history, in order to realize the informatization of the evolution process of place names, a large number of digital maps and historical geogr...
