Embodiment Construction

[0022] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In preferred embodiment of the present invention, comprise following three steps:

[0023] (1) search for a dynamic address, and store the searched dynamic address into a dynamic address library;

[0024] (2) analyzing the dynamic address library, storing the addresses of the dynamic space information system and the reference information of the dynamic space system in the space information system address library;

[0025] (3) Establishing a spatial information index according to the reference information.

[0026] In one embodiment of the invention, the search for the dynamic address is performed using a web searcher). Such as figure 1 As shown, to search for a dynamic address, perform the following steps:

[0027] 1-1) Take out the first address from the candidate webpage address library, and obtain the corresponding webpage; the first addre...

Abstract

The invention discloses a search space information system method and space information inquire method with the method, which comprises, (1) search dynamic address from web page and store the result to dynamic address database;(2) analyze the addresses and store the addresses existed dynamic space information system to space information system address database;(3) obtain reference information of dynamic space from address database, and build space information index according to built reference information. By the method of this invention, network space information with no any relation and dispersive on physics forms a completed space information system on logic, with good expansion and benefit to all inquire.

Description

technical field [0001] The invention relates to a method for searching a space information system and a method for querying space information by using the method. Background technique [0002] For decades, business departments such as planning, water conservancy, geology, meteorology, and surveying and mapping have accumulated gigabytes of digital information about space entities on the earth's surface. LANDSAT land satellites can take pictures of the whole world in two weeks. NASA (NASA)'s "Planet Earth Project" can generate 1000GB of data every day. However, the utilization rate of these raw data is very low. [0003] In fact, 80% of the data in human life is related to spatial data. Therefore, how to make full use of these spatial information has increasingly become an important issue. [0004] At present, with the help of Internet mapping technology (Web Mapping), Internet-based spatial information sharing has made great progress. The number of sites providing spatia...
