A METHODOLOGY FOR DEVELOPING REMOTE SENSING APPLICATIONS

Abstract

Remote Sensing Application (RSA) is important as one of the critical enabler of e-systems such as e- government, e-commerce, and e-sciences. In this dissertation, we argue that owning to the specialized needs of RSA such as volatility and interactive nature, a customized Software Engineering (SE) approach should be adapted for their development. Based on this argument we have also identified the shortcomings of the conventional SE approaches and the classical Waterfall software development life cycle model. In this research work, we have proposed a modification to the classical Waterfall software development life cycle model and then using this modified classical Waterfall software development life cycle model as a framework we have proposed a customized software development methodology for RSAs. The proposed development methodology works in two steps, the first step works when a RS application is being developed from scratch, and the second step operates when a change occurs to an already developed RS application. We have identified four (4) different types of changes that may occur to an already developed RS application, the proposed methodology is capable to incorporate all four types of changes. We have successfully demonstrated the applicability of our proposed methodology through three case studies.
