Design and implementation of heterogeneous sensor registry category service

With geographic information resources continuous expansion and the rapid development of the web technology, the demand of integration geographic information resources become increasingly strong. Category Service for the Web (CSW) is the fundamental Service for registering and querying sensor information in the Internet. This paper is dedicated to design and develop a heterogeneous sensor registry category service system GEOSENSOR-CSW. In order to improve the completeness of the sensor information stored in this system, this paper adds new elements of ebXML Registry Information Model (ebRIM) and add new mapping relationships of Sensor Model Language (SensorML) element and ebRIM element. This paper registers some hydrological sensors which are used to monitor flood into GEOSENSOR-CSW successfully and analyses those mapping relationships of some hydrological sensor information elements between SensorML document and corresponding ebRIM document mainly. The experiment result shows that GENOSENSOR-CSW can improve the completeness of the sensor information stored in this system effectively.
