The accuracy of soil moisture depends on these sensors' observation capability. Current methods have simple inference rules to provide obvious results for users, which have not clear connection between the sensors and specific application. This paper proposes an ontology and the reason rules of observation capability about optical satellite sensor, in order to mine deeper observation capability of...
It is a needful and challenging work to integratedly manage the massive, distributed and heterogeneous sensor resources for a cooperative observation task in smart city context, especially for the cooperative task of dynamic environment monitoring, timely emergency response and citizen safety guarantee. Regarding the heterogeneous sensor resources that immersed in the cities, there lacks an open and...
Under the circumstance of earth observation data booming, it is important to develop an intelligent and automatic processing method for the geospatial data. Currently the OGC web services standard offer unique interfaces for the geospatial data planning, accessing, processing and publishing. This paper focuses on the Web processing model building and implementing — how to organize the distributed...
In the era of high-frequency occurrence of natural disasters, users are more urgently concerned with the sharing of the satellite sensor resources information and coordinating the complement of sensor observation. However, the capacity of discovering, retrieving and visualizing the sensor resource information accurately based on heterogeneous sensors over sensor network is very limited. This paper...
Disaster emergency is important for relieving the damage and mitigating the loss to human. Conventional disaster emergency processing presents a phase of separated, passive and time-lag response mode. Open Geospatial Consortium (OGC) sensor web works in associated environments that integrate heterogeneous sensor-intensive resources into an interoperable and controllable system through the web. This...
Nowadays, the Sensor Web provides a new way for sensor planning and observation service, whereas, how to couple diverse satellite observations with specified forecast model for weather support decision service under Sensor Web environment is a big challenge. This paper proposes a new framework for put data assimilation into a forecast model. The framework is realized based on the Sensor Web Enablement...
A new method for serving observational data, based on a reusable geo-processing workflow (GPW), is proposed in order to meet the requirements of the automatic AutoChem data feed service in the sensor web environment. A service-oriented architecture (SOA) is adopted. The system has three roles: the GPW provider, registry center, and portal. The system has GPW design, deployment, registration, search,...
