Study And Design On Digital-Appeal And Approval System For Urban Planning Administration

With the city construction being accelerated, urban plan business amount enhances bigger and bigger. The traditional plan is revealed out many problems, such as approving accuracy, poor efficiency and data is difficult to store. That Digital-Appeal and Approval is one kind of new examining and approving way that brought forward by the urban planning administrative department in the past few years, the most important part is the examination of general layout and building engineering scheme in site plan. Now, a great many cities has carried out Digital-Appeal and Approval system, but there are lots of problems. First, the function of the system is not so strong that it can only can automatic calculate the economic index, the amount of people in design company is too big, and it cannot satisfy the need of high efficiency. Second, the data standardization is not perfect, the database of urban planning result hasn't been built, and also the data cannot share with other database.Urban planning management system (UPMS) is the main method to manage urban planning in information age. The article analyzed system structure composition, the data circulation at present. It was discussed in detail the workflow, process model data organization and system design in Digital Appeal and Approval. And take that ARC/INFOR as urban planning Management Information System platform for example, discussed the changing methods from the format of CAD to the format of GIS. The author developed a new scheme to renovate the data of foundational geographic database. Trough these studies, urban planning bureau can make good use of these data.The requirements analysis is the main content to build the project of digital appeal and approval system. According to the actualization in Nanjing, the author make plenty communication with the designer, and at last make clear requirements of the system. Based on the current situation and theory of software engineering, under AutoCAD platform criticizes system, comparison by several kinds repeated exploitation method, ultimate select and use give first place to VBA exploitation, make use of AutoLISP language to wait to expand whose function at the same time, more multifunctional assisting having developed out energy realization designs that digital examining and approving system.
