摘要：A system's architecture has been designed to exploit earth observation and field survey data. This architecture has the task to combine, analyse and present information from earth observation sensors (satellite and airborne) as well as data from field survey. At the top architectural level, the system is decomposed in the following major subsystems: the mission planning system, the workflow management system, the information management system, the data ingestion system and data analysis system. An overview of the architecture is given with the data analysis described in more detail. One of the noteworthy aspects of the system is its compatibility with the ESA KEO architecture, allowing access to earth observation data and services. A prototype of this system will be deployed for the field trial in Angola. For the trial area there is a substantial lack of information and the little available data is described. Land cover classification is performed based on (freely) available satellite data land; demonstrating some the potential of the system
