SVG-based Web GIS building room query system and query method

Abstract

The invention discloses a SVG-based Web GIS building room query system and a query method; the query system comprises an image acquisition system, a building room query Web server and a local building room query system; wherein, the local building room query system is connected with the building room query Web server through Internet or LAN. The query method includes the following procedures: the query information is inputted to the local building room query system, the building room query Web server searches the XML files of building room attributes and calls the SVG file which stores the building room graph correspondingly, and then the SVG file is marked to inform the user the specific location information of the queried room. The SVG-based Web GIS building room query system and the query method has reasonable design, low investment cost, high query speed and good query effect, also has high popularization value, can solve the defects that the building query method in prior art has high investment cost, complicated operation procedures, and lacks of generality and flexibility in practical application.

Description

technical field [0001] The invention belongs to the field of internet geographic information system (WebGIS) application technology, and in particular relates to an SVG-based WebGIS building room query system and a query method. Background technique [0002] With the rapid development of urban construction, various styles of high-rise buildings have sprung up. The complex and diverse buildings make it more and more difficult for people to go out to find buildings and rooms. It is urgent to provide visual specific physical location query services. At present, the query methods of buildings and rooms include: database mode, GIS (Geographic Information System) mode and WebGIS (Internet Geographic Information System) mode. The database method is to store the building number and room number through the establishment of the database, search through the SQL language, and display the search results in the form of a table. The main disadvantage of this query method is that the searc...

Problems solved by technology

The main problems of this query method are: each client must be equipped with expensive professional GIS software, the cost is too high; maintenance costs are high; data sharing is difficult; operation is complicated; it does not have cross-platform features

If you need to query the newly built buildings, you must redesign and implement the query system, so it does not have flexibility and versatility in actual application
