3 Introduction Background In precision agriculture, planning, execution, monitoring and assessment of farming processes are based on spatially referenced data decision-making requires data from many sources, e.g. farm based sensors, equipment and software partners, advisors, authorities external services and databases Improvements in crop production are achieved by using analyzed data in decision-making (Adapted from Pesonen et al. 2010).
4 Data requirements in precision farming, e.g. good quality and accuracy easy integration and transfer between different hardware, software, and information systems integrated analysis and transformation of data into useful information effective management of GIS data Farm management information system (FMIS) for precision agriculture
5 Suitable technologies for the implementation of FMIS for precision agriculture, e.g. Communication: SOAP, ISOBUS Data transfer XML (e.g., GML, ISOBUS-XML, AgroXML) Data storing: Relational and spatial databases (e.g, PostGIS) Geosensor networks (e.g., Nittel et al. 2004) Location platforms (e.g., Chu & Buyya 2007) Standards of Open Geospatial Consortium, e.g Sensor Web Enablement (SensorML) OpenGIS Location Service (GMS) OGC Web Services (WMS, WFS, WCS, WPS)
6 Motivation New methods for FMIS design available cf. research results achieved in InfoXT, CropInfra and FutureFarm projects (e.g., Pesonen et al. 2008) Currently there is a need for FMIS pilots and tests We will try to give our contribution to this discussion
7 Research Focus To develop and implement the acquisition, storage, transfer, and management of spatial agricultural data To demonstrate interoperable solutions for the FMIS by applying a location-based service platform and a technology of geosensor networks To assure the quality of spatial data by utilizing appropriate standards: ISO 11783 and OGC s standards
8 Implementation of the system Locawe Platform Location-aware system platform developed at CENTRIA Research and Development, Ylivieska, Finland Client-server solution for outdoor and indoor conditions Consists of mobile units and servers for services, e.g. tracking and communication Enables creation of user interfaces, which include location and sensor data, and different media formats
9 Locawe field experiments: Remote monitoring mobile robots (Luimula et al. 2010) Communication techniques in parallel learning (Sääskilahti et al. 2010) Route visualization techniques (Lehtimäki et al. 2008) Techniques for location selection (Luimula et al. 2007) Automatic rotation and zooming (Partala et al. 2006) Speed-dependent camera control in 3D mobile maps (Partala et al. 2009)

11 Conclusion Basic functionality of the system architecture was demonstrated and tested. Interfaces fulfilled requirements for interoperability and scalability. The use of chosen standards tackled both interoperability and quality requirements.
12 Future Work Evaluation of a full performance in a near-deployment phase Implementation of new interfaces Web Coverage Service: delivery of the spatial data in raster format Web Processing Service: functionalities for geospatial processing of data Study of user acceptance and user experiences
