Standards-based sensor web for agro-informatics applications

In a developing country like India with its overgrowing population, increase in agriculture productivity and its monitoring is an important concern. Hence, environmental data in conjunction with crop information (e.g. soil moisture) are necessary for crop management and productivity enhancement. Enhanced monitoring and seamless information exchange in real time is only possible if data from these sensors are standardized. This also enables integration of data from several related areas of interest and facilitates interoperability. We propose Open Geospatial Consortium (OGC) standards-based Service-Oriented Architecture (SOA) for data integration. The Sensors Web Enablement (SWE) framework from OGC has been implemented for selected sensors belonging to the agricultural domain. OGC´s Sensor Observation service (SOS) (part of SWE suite) is adapted for discovery and access of sensor observations (real-time or archived) and Sensor Event Service (SES) for sending alerts and notifications.
