TOWARDS A SOLUTION FOR THE PUBLIC WEB-BASED GIS MONITORING AND ALERTING SYSTEM
Jitka, Hübnerová · 2014
This paper deals with the issue of interoperability of heterogeneous sensor systems and the availability of their data from a global perspective. We show the application of previously developed WEDA architecture style into a GIS based experimental system and we present the performance analysis results of the system. The paper also presents its strengths as being a firewall-friendly, web-standards based solution that can be plugged into existing applications without needing to completely rewrite them (which is good when using OGC Sensor Web Enablement services). The paper compares the new style with styles which are used today in OGC Webservices. We then present an alpha version of the experimental system with eventing enhancements that are available with the new style. These principles will be applied from the experimental system to the final draft specification and API after more tests. If such a web-service standard meets the new binding possibilities, alerting will become widely accessible and GIS viewers and sensors can improve userexperience, loading/publishing sensor data or loading pipelined WMS tiles as well.
