The Sensor Observation Service (SOS) is a web service to query real-time sensor data and sensor data time series and is part of the Sensor Web [1]. istSOS is a Sensor Observation Service application developed by “Institute Scienza della Terra”, for data gathering and service through the usage of the Sensor Observation Service OGC standard [2]. Currently this platform will give the results in a XML format. There is no client-side offered in a user-friendly interface, either desktop or web-based. This implies that for the user to get the information, he/she needs to get the XML file, parse it, and then create tables or charts through one of programming languages or applications that deals with charts. In order for a user to be able to browse easily and same time to get the observing results in a “known” formatting according to some specific criteria set by him/her, we worked towards a more integrated application, especially towards a Javabased application that will be able retrieve information about the sensors and their observation and present them through “user-friendly” interface – globe, based on NASA World Wind application. Consumption of the service is done through URL, the return result of service is XML format, which is parsed and then the information retrieved is inserted in the corresponding developed java classes. The core part of the application (classes, transfer objects, data access objects) is developed by using MVC pattern. These classes then are called through NASA World Wind based application. NASA World Wind based application is developed in a way that that will show the sensors in the globe and through annotations will give observation information for every sensor. The information includes: sensor name, feature of interest, start period of observation, end period of observation and observation values.
