Location aware management and location based automation are fast upcoming technologies which are facilitated by availability of reliable, accurate, and cheap global positioning systems and location based services. This paper discusses the development of C++ classes, which may be used for development of software for location aware management and control, specifically in merchant shipping, so as to provide improved safety, increased automation, prevention of pollution and reducing the work burden of the crew. The GPS is used in conjunction with the regionally accessible nested global shorelines (RANGS) dataset for this purpose. The design of two main C++ classes named CShorelines and CGPSInput have been discussed. A control system mandatory on all oil-tankers above 150 GRT (and few other vessels) called ODMCS has been made location aware using the novel software developed and the results obtained have been critically examined and presented. 展开更多
