摘要：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 INSP IRE (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 applied, others like SOS (Sensor Observation Service) are still a work in progress and need some revisions and verifications for their correct application. The SOS primary aim is to provide a standardized service for accessing observations in a standard format. The secondary aim is to provide to intelligent sensor network an interface to interact with for automatic sensor registration and observation storage. In order to investigate the maturity level of the version 1.0 of the SOS OGC standard, the IST (Institute of Earth Sciences) has developed a new software implementing this standard and has applied it for the management of the hydro-meteorological network of the Canton Ticino. The development of the new software, which is named istSOS, together with its application in a real case has provided the opportunity to evaluate some open issues, weakness and lacks that are discussed in this paper. As a result the authors can overall conclude that the SOS v.1.0 is currently incomplete and still open to ambiguities but with some corrections it can easily be an invaluable resource for a great number of disciplines and actions, including climate changes, risk reduction, security improvement
