Abstract:

A geospatial sensor network combines wireless sensor network with GIS, GPS and satellite remote sensing efficiently, but at present, it has no uniform architecture. So an architecture of geospatial sensor network oriented to water quality monitoring was proposed, and the design and implementation of data management subsystem is the main content. The software design of data management subsystem was based on service oriented architecture (SOA), since the monitored data is distributed, multiple sourced, and heterogeneous. Rich internet application (RIA) was the main developing mode in the software, so it has auto update, loading balance, and some other advantages. Compared with the traditional water quality monitoring approaches by the application in Ontario, Canada, this architecture can monitor more data, and visualize them more directly.

Key words: geospatial sensor network, water quality monitoring, service oriented architecture (SOA), rich internet application (RIA)
