Dynamic Visualization of Urban Changes Based on Flex
The advent of programmable vector graphics on the web has major implication for web GIS. Macromedia Flash as a plug in possesses many characteristics. However, Flash is more suitable for designer not for a programmer. Especially in the temporal GIS. Furthermore, Flash takes much time to generate SWF files. Therefore, Flex is an alternative. It has better messaging infrastructure and data synchronization. The paper provides a method to display the urban change using Flex 4.6. Another attraction of the project is the use of the Web Service which link Flex to the database. The result shows that it is easy to dynamically display the urban change using Flex and Flex is easier for web applications than Flash. Other benefit of the work is the service can be used in other application or by other people.
