Urban construction archive submission system with WPF technology

With rapid development of urban construction, there are more and more urban construction archives, more and more types of construction archives. The traditional ways for submitting the urban construction archives, such as paper-based submission, disk-based submission and email-based submission, can´t meet the much more complex demands. The shortage of paper-based way is that it can´t be in time and that the submitted archives can´t be used for building the digital database. In disk-based way, the paper documents normally are converted to electronic form and then submitted. But because of the delay of the disk delivery, the submission is also not in time. Email-based way improves the efficiency of submission. But because of the size limitation of email and its security shortage, this way can´t meet complex submission. One solution for submitting the urban construction archives remotely is proposed to overcome above shortages based on Windows Presentation Foundation (WPF). WPF separates the presentation from its behavior, so that designers and developers can work at separate models. WPF possesses not only many characteristics of desktop applications, such as rich interactive ability, but also some special advantages, such as rapid and low-cost deployment. As one of efficient RIA technology, WPF supports both online and offline work and is very suitable to be based on for developing remote submission system. WebGIS is also used in the browser-based management information system of the urban construction archives to present the spatial information of the submitted archives. The system framework, and some technique details about data organization at client, data packaging at client, data transferring between client and web service, and WebGIS support in server system, are introduced. The developed software is now used by the Urban Construction Archives Agency of Shaoguan City and Zhenjiang City of China. The effects show it works very well.
