Evaluation and Modelling of a Standard Based Spatial Data Infrastructure for Precision Farming

Geospatial information is becoming available increa singly in digital representations and can be created and consumed with the help of variou s different devices and services. Due to the increasing application of precision farm ing techniques the importance of spatial information and their implementation has be come a key issue in operation planning and application in agriculture. Within the ICT-agri funded project GeoWebAgri present precision farming workflows for geo-data handling and data exchange have been analysed. User groups in the precision farming domain, consis ting of heterogeneous users like farmers and many others, have identified the benefi ts of the idea of precision agriculture. Nevertheless the current usage of thos e techniques is still inhibited by nonflexible, restricted and hard to use systems. Ident ifi d by a survey, the concept of a Spatial Data Infrastructure for Precision Farming a pplications (SDI-PF) was developed to particularly overcome the problems of geodata ha ndling, because present Farm Management Information Systems (FMIS) and precision farming tools fulfil the needs only partly. The information-intensive, location-re lated tasks of precision farming were analysed and decomposed. Following the concept of M odel Driven Architecture (MDA) a conceptual model was developed using the Profile f r GML application schema of the Unified Modelling Language (UML). The derived physi cal models can be used to exchange PF data in an infrastructure, based on a s erver-client communication, driven by web-services and the standards from the Open Geo spatial Consortium (OGC) and International Standardization Organization (ISO). T he approach was tested by modelling an exemplary application of precision wee d control and made a positive outlook for the integration of tailored services in to existing task controlling, as well as maintaining interoperability with ICT-infrastructur es of close-by domains.
