A Reusability and Efficiency Oriented Software Design Method for Mobile Land-Inspection
Aiming at the requirement from the real-time land inspection domain,a land inspection handset system was presented in this paper.In order to increase the reusability of the system,a design pattern based framework was presented.Encapsulation for command like actions by applying COMMAND pattern was proposed for the problem of complex UI interactions.Integrating several GPS-log parsing engines into a general parsing framework was archived by introducing STRATEGY pattern.A network transmission module based network middleware was constructed.For mitigating the high coupling of complex network communication programs,FACTORY pattern was applied to facilitate the decoupling.Moreover,in order to efficiently manipulate huge GIS datasets,a VISITOR pattern and Quad-tree based multi-scale representation method was presented.It had been proved practically that these design patterns reduced the coupling between the subsystems,and improved the expansibility.
