Technical Study On Campus Map And Drawing Exchange File Processing Based On CS Architecture

The development of Internet era, the commercialization trend of Internet and the booming of GIS provide convenient conditions for the construction of a digital campus map in universities. The construction of a digital campus map not only shows a university’s comprehensive strength, but also makes everyone in the university travel more convenient. As one of the higher education institutions of Shandong province, Shandong University has founded its campus in Jinan, Qingdao and Weihai respectively. The construction of a digital campus map can make students and teachers’ travel more convenient. What’s more, Shandong University’s campus is cross-regional. The campus covers a large area and the buildings are intricate. Therefore the public housing asset data information of Shandong University is complicated and the amount of the data is quite huge, which brings great challenge for the management of public housing information.Currently most of the university’s digital campus map are based on BS architecture, while Shandong University’s working concept is to choose between BS architecture and CS architecture according to user’s requirements. Therefore, it is a basic demand to construct Shandong University’s digital campus map both on BS architecture and CS architecture. This paper mainly studies the organization structure of Google Map and how to realize the quick display of a digital campus map on Google Map based on CS architecture. Aimed at the quick display of a digital campus map, this paper puts forward a solution by combining concurrency and cache in order to quicken the display speed of a digital campus map.Currently the management of the drawing of public housing asset in Shandong University is achieved by means of AutoCAD software. The first problem to be solved in this paper is how to redraw the drawing of public housing asset and reappear on CS architecture. In response to this issue, this paper studies the organization structure of DXF Interactive graphical interface file provided by Autodesk Company. Based on the mastery of the organization structure of DXF interactive graphic file, the DXF file can be analyzed and valid graph data can be extracted. At last, with the help of Java2D technique, the redrawing of the extracted graphic data can be accomplished. The public housing asset also has other attribute information, such as the purpose of the public house, its user, etc. which are recorded by Excel files. As a result, the information on the drawing and the attribute information are separated from each other. The second problem to be solved in this paper is how to establish the association between public housing asset’s attribute information and its drawing. To address this issue, this paper comes up with two strategies to extract the frame of the house:automatic extraction of the frame and manual extraction of the frame. Then the association with the attribute information of the house in the database is established according to the house number within the extracted housing frame.By studying the issues related to the digital campus map displayed within CS architecture, this paper creatively realizes the quick display of digital campus map within CS architecture, which satisfies the needs of those managers who are partial to CS architecture. Based on the study of DXF interactive graphic file, this paper manages to extract graphic information of DXF file and realizes the redrawing of the graph. After that, the two strategies of automatic extraction of the frame and manual extraction of the frame are used to establish the association between the attribute information of the house and its drawing. It lays a foundation for the display of more attribute information of the house in the drawing.
