Exploiting observations and measurement data standard for distributed LTER-Italy freshwater sites. Water quality issues

Abstract

Water quality is a multi-source, multi-purpose problem that needs exploiting observations, often taken by a number of heterogeneous bodies. This problem has been tackled within the Italian Long Term Ecological research network (LTER-Italy) in an experiment aimed at testing how ecological observations of mountain lakes water can be shared by OGC (Open Geospatial Consortium) standard services of the Sensor Web Enablement (SWE) initiative. A friendly and easy implementation of these services is fostered by the usage of the open source software Geoinformation Enabling Toolkit StarterKit ® (GET-IT). It has been used in the experiment to create SOS services, upload observations and create SensorML metadata of the involved sensors. This contribution describes the experiment and presents its results.

A Methodology for Heterogeneous Sensor Data Organization and Near Real-Time Data Sharing by Adopting OGC SWE Standards

“…Addditionally, the GET-IT (http: //www.get-it.it/) system integrates the 52 • North SOS project for distributing observation data and metadata of sensors, according to the INSPIRE directive. It offers a user-friendly web interface which can effectievly simplify the use of the SWE standards, especially for non-expert users [15,16]. As mentioned before, the heterogeneous and dynamic market of sensors does not fit with the concept of standardization.…”
