This is a system project report explaining Earth observation project undertaken during my internship with XSealence S.A. The project was proposed by the company but since it was a large project it was divided into small several units and assigned to various groups. The report has been divided into various chapters which discuss the software development life cycle of Earth observation system. the project used agile development model which allowed the project to be divided into various phases. The first phase is discussed in the first chapter which helped state the motivations behind the project. Buoyed by rising demand for marine weather forecast XSealence S.A company developed a marine weather monitoring web application to monitor and predict weather data based on data downloaded from Copernicus marine monitoring service. So as to have an installable system that can be installed on sea vessels XSealence S.A developed a desktop version of the same. This report discusses the development of earth observation system which is the part of the main desktop application. The aim of developing earth observation was to help predict the marine weather. The project initialization involved setting project aims and goals which were to guide through the development process. The main project goal was to deliver a desktop application that will help forecast marine weather. The application was linked to Copernicus marine monitoring service where it downloaded data in a .nc format and converted to .txt format. The system requirement phase involved the collection of functional requirements of the system. With the help of my supervisor, it was established my part of the main system only needed to predict marine weather including water and ice speed, water velocity, sea surface height, temperature among other marine weather options. These capabilities of the system helped in system design and development to ensure the final product meets the set targets. UML diagrams including use case, data flow diagrams helped illustrate the flow of information in the system. These designs together with class diagrams were converted into a working solution during system development phase as planned in the project planning phase of the agile methodology. The system was tested for the achievement of system goals and objectives as stated in system functional requirements. Functional requirements achievement was tested using test use case. The test case tested every functionality of the system to establish the non-achieved goals and objectives. These defects found were communicated to the developer for correction in the subsequent releases. The system has been handed to the XSealence S.A for integration with another main desktop application. The entire system maintenance and deployment will be done by the company. To close the project, documentation was done to cover all activities of the project.
