Open standards and interoperability are key issues in modern agriculture information management for precision farming. A collaboration of heterogeneous user groups from different backgrounds with the need to access common spatial data sets benefits with an extensible and open structure, while the data can be created and maintained throughout different systems, located either on farm machinery and local offices or being accessible through the web. The need to pass spatial data sets around, requires systems capable of i) handling ii) interpreting and iii) im-/exporting geo-data. An integration of new precision farming tasks into existing Farm Management Information Systems (FMIS) can be achieved with a decentralised model of services. Current FMIS and precision farming tools support these needs to a limited extent.
The present project will continue the work initiated in the GeoWebAgri project by identifying and specifying an application schema for precision farming operations management in the Unified Modelling Language (UML). Based on the findings in GeoWebAgri, the selected exchange format will be the Geographic Markup Language (GML) specified by the Open Geospatial Consortium (OGC) and ISO 19136. A set of conversion rules will be identified and implemented in a tool that reads UML class diagrams and writes corresponding GML code. A test case of an instance of field operations management tasks will be defined and subjected to test and demonstration validating the defined data model.
