  • 摘要:Recently, there is a large tendency toward using modern technologies specially those systems whose are intelligent and in hand, every where and every time. Sensor technology is one of the important technologies that were introduced in the recent years. In future, we may have a world wide network of sensing devices that collects all kinds of input from various environments, assesses that input, and then shares it with us humans over a worldwide computer grid. A network of sensors can perform as an extensive monitoring and sensing system that provides timely, comprehensive, continuous and multi-mode observations. This new earth observation system opens up a new avenue to fast assimilation of data from various sensors and to accurate analysis and informed decision makings. One of the critical components in developing a sensor web is to build a geospatial information infrastructure, a backbone that connects the heterogeneous in-situ sensors over the wired or wireless networks. Although, with the rising trend to using of sensors, it is too important to have powerful and fast access to their collected data and themselves either, at any time and place. For comply these needs, having standard metadata for sensors and their collected data is essential. In this way, by using metadata technology, sensors can be searched via their standard metadata. Moreover, for full access to wanted sensors and data, a web-based system would be the best alternative, in which accessing and sharing of data through the whole world, by using World Wide Web will be possible
