Marine information monitoring plays an important role in solving marine environment and controlling marine ecology. OpenLayers, as an open source development tool for WebGIS client, has the characteristics of small size and powerful function compared with commercial WebGIS software. This paper discusses the application of OpenLayers in ocean information monitoring based on OpenLayers. Firstly, The paper gives a basic overview of OpenLayers, then summarizes its related research, constructs the system framework for ocean information monitoring system and discusses the related key technologies. Finally, it studies the application of ocean information monitoring. From the research point of view, open source OpenLayers performs well, meets the general needs of marine information monitoring, and can significantly reduce development costs.

This paper presents an empirical analysis of the Open Source development process from the point of view of the involvement of the developers in the production process. The study focuses on how developers contribute to projects in terms of involvement, size and kind of their contribution. Data have been collected from 53 Open Source projects and target application domains include different areas: web and application servers, databases, operating systems, and window managers. Collected data include the number of developers, patterns of code modifications, and evolution over the time of size and complexity. The results of this study show evidence that there are recurrent patterns in Open Source software development and these patterns are common to all the projects considered even if there are no superimposed processes for development, application domains are different, and there are contributions from people spread across the world.

Too often, computer science programs offer a software engineering course that emphasizes concepts, principles, and practical techniques, but fails to engage students in real-world software experiences. The authors have developed an approach to teaching undergraduate software engineering courses that integrates client-oriented project development and open source development practice. They call this approach the Client-Oriented Open Source Software (CO-FOSS) model. The advantages of this approach are that students are involved directly with a client, nonprofits gain a useful software application, and the project is available as open source for other students or organizations to extend and adapt. This chapter describes the motivation, elaborates the approach, and presents the results in substantial detail. The process is agile and the development framework is transferrable to other one-semester software engineering courses in a wide range of institutions.
