Design and implementation of statistic remote sensing platform based on design patterns

The ldquosoftware crisisrdquo outbreak in 1960s continues to this day. The process of software development faces a number of serious problems; software reuse is the fundamental approach to solve this problem. Design patterns is one of the typical way of software reuse, is the basic of reusable object-oriented software design. In order to reduce the influences of a variety of functions and non-functional problems in software development process, this study integrates the features of remote sensing and GIS software, and put forward several application cases based on the classic GoF design patterns. These cases had been applied to the ecological resources statistics remote sensing platform successfully, and greatly improved the software´s scalability and flexibility.
