The attribute data of the spatial data is retained, so that users can query the model attribute negatives when browsing on the Internet, truly achieving the purpose of the 3D virtual reality geographic information system. [Previous technology] Geographic negative sfL system is a digital map technology, which can convert ambiguous geographic data (such as road and street addresses) into clear map locations and store them in digital map files. These digitized digits Maps can be used for display, query and analysis via GIS. The geographic information system is integrated with computer mapping, remote sensing detection, database management system and computer-aided design. In recent years, with the continuous innovation and progress of computer technology, GIS has been widely used. It is generally used in the following four Aspects: 1 · Graphic data production and updating: Traditional graphic data production is based on artificial margins, which are not only time-consuming, time-consuming, error-prone, and difficult to modify. Nowadays, computers use GIS tools for drawing and retouching. Not only is it easy, fast and accurate, but it is also easy to update. At the same time, computer files can be reused again and again, and aerial or satellite telemetry image maps can be timely and accurately modified as base maps. 2 · Graphical data management: Traditional graphic data management uses various paper maps and graphic cabinets. Over time, it often faces the difficulty of flooding papers and being unable to retrieve them.

Query display: When using the G I S tool for querying, multiple conditions can be combined to perform compound querying. Statistical analysis can be completed simultaneously during querying. The query results can also be displayed in combination with spatial information, which is clear and easy to understand. 4. Decision support aspect • Through the analysis function of GIS, decision makers < do a variety of simulation analysis to obtain various decision data to maintain the objectivity of the data and increase the correctness of the decision. The application of GIS has been gradually applied from the stand-alone application to the direction of the Internet. However, the current Internet application still displays geographic information in a flat way, which is less likely to show the real terrain. Today's 3D virtual reality technology Gradually mature, using 3D virtual reality technology to display geographic information is the development trend of GIS in the future. For the more commonly used GIS software ArcGIS and Map Info in China, 3D analysis modules have been successively launched, hoping to transform the terrain More realistically presented in front of users. At this stage, some GIS websites can be found on the Internet, such as the Taiwan electronic map website (www.map.com.tw), Fengjia University Ren Xiaoyao website (www · easymap · com · tw), etc., which are quite successful. GIS websites, but the geographic information that these websites can present to users is traditional flat information, and it is impossible to present the face of the real world to users. At this stage, the application of G I S visualization is limited to a single machine. It is still relatively rare on the Internet. The main reason is to apply 3D technology to web-based geographic information systems (W E B G I S).

Description of the invention (3) The present invention is not designing a 3D virtual reality edge map engine, but uses the current standard virtual reality technology VRML as a technology platform to invent Refocus on how to convert 2D G IS plane data into VRML data format that can describe 3D g is virtual reality. Currently, there is a way to implement the virtual reality 11 environment of the 3D G IS Internet. One way is to directly use G 丨 S software to generate virtual reality job files. The Chinese University of Hong Kong Bo Huang used the 3D edge map software ArcView to cooperate with its 3D analysis software 3D Analysis and Internet Map Server (Internet Map Server). GeoVR system (see the first picture), when the user uses the user's computer 1 0 〇 to connect to the 3D G IS website of the Internet map server 3 0 0, the GeoVR system 301 The space specified in the user's specified area is captured in the spatial database 3202, converted into a VRML file format, and then returned to the user's computer's browser for display. Generally speaking, using this method to generate virtual reality operation files is the most time-saving way, but there are two disadvantages: (1) You must spend extra to buy 3D and internet map server (Internet Map Server) modules 〇 (2) The virtual reality operation file generated by the 3D module turns the original spatial object in the 2D GIS into a single spatial object, so the user will not be able to link or query the attributes of the object. In order to solve the above problems, Carson (1 998) proposed another solution 'Carson uses CAD software to generate VRML virtual reality files, β Hai Fang / will first use art software (such as Adobe Illustrator) to generate 20 maps' Then use Meta Creations Ray Dream Studi 〇 software
