2、Electronic Map of Campus Based on WEBGIS I. INTRODUCTION Nowadays, digitalization and informatization are the theme of our times. With the development of information revolution and computer science, computer technology has penetrated into all fields of science and caused many revolutionary changes i

3、n these subjects, the ancient cartography also cant escape. With the technical and cultural constantly progress, the form and the content of the map change and update as well. As the computer graphics, geographic information systems (GIS) constantly applied to the Web, the conventional way of fabric

4、ation and demonstration has suffered great change, and the application of the Map has extended dramatically owing to the development of advanced information technology. Under these circumstances, cartography will be faced with promising prospect. It has branched out into many new products. One of th

5、e products come into being is the e-map 1. With the rapid development of the computer technology, computer graphics theory, remote sensing technology, photogram metric technology and other related technology. Users require handling and analysis of three-dimension visualization, dynamic interactivity

6、 and show their various geo-related data, so much attention should be paid to the research of three dimensional maps. This article based on the Northeast Petroleum University and its surroundings designs and creates the three-dimensional electronic map. II. FUNCTIONDESIGN Three-dimensional electroni

7、c map system of campus based on WEBGIS has general characteristics of the common maps. Through pressing the arrow keys (Up, Down, Left, And Right) on the keyboard, one can make the map move towards the corresponding direction of translation. Through dragging mouse, one can see wherever he likes. Usi

8、ng the mouse wheel, you can control a maps magnitude, according to the users needs to view different levels of map. The lower left of the map where will display the current coordinate 内蒙古工业大学 本科毕业设计 外文文献翻译 2 of the mouse on the map. In a div layer, we depict a hotspot of new buildings, this layer ca

9、n be displayed according to the different map layers, it also can automatically scale. By clicking on hot spots, it can show the hot spots specific information. One can also type into the query information based on his need, and get some relevant information. In addition, one can choose to check the

10、 three dimensional maps and satellite maps through clicking the mouse. Major functions: User information management: Check the user name and password, set level certification depending on the permissions, allow users of different permissions to login the system via the Internet. The inquiry of Locat

11、ion information: System can provide users with fuzzy inquires and quick location. Map management: Implement loading maps, map inquires, layer management, and other common operations such as distance measurement, and maps zoom, eagle eye, labels, printing, and more. Roam the map: Use the up and down

12、keys to roam any area of the map, or drag-and-drop directly. III. THE PROCESS OF SYSTEM DEVELOPMENT To the first, we collect the information which contains the outward appearance of architectural buildings, the shape of the trees the design of the roads. And then, we construct three dimensional scen

13、es with 3DS MAX software 2. That is to say we render the scene and achieve the high-defmition map, after that we cut the map into small pictures with the cut figure program, at last we built the html pages which can asynchronous load maps and achieve the function of the electronic maps. The flow chart of the system development will be shown in Figure 1:
