Title

INVESTIGATION OF THE SOS AND WPS OGC STANDARDS

Abstract

Approving the new federal low about geo-information (RS 510.62), the Switzerland gave a great impulse to the establishment of a national spatial data infrastructure, which in agreement with the EU directive INSPIRE (2007/2/CE), shall be based on geo-services. This approach gives to data maintainers the freedom to choose the desired formats, software and data model but impose the provision of the required information throughout a well defined service. While some of the Geographical Web Services, like WMS and WFS, are today widely diffused and applicable out of the box, others like SOS and WPS are still rare and mostly applied in research or not critical application.

While Sensor Observation Service primary aim is to provide a standardized service for accessing observations in a defined format, Web Processing Service primary aim is to provide processing capabilities to applications and users defining rules for handling inputs and outputs.

As evinced from their scope, SOS and WPS are ideally closely linked in hazard forecasting system where on demand simulation require on demand latest updated data.

In order to investigate the maturity level of this two standard and to test their capabilities and applicability in an hazard management systems, the authors apply them to test the migration of an official flood forecasting system for the Maggiore lake that has been developed and is currently managed by the Institute of Earth Sciences (Istituto Scienze della Terra, IST).

As a result of this case study, the authors will present the development steps and will discuss the outcomes in relation to the existing and currently applied system.
