The software described in the building blocks above by default is always open. There are circumstances that it is desired to disable information to be available for non registered users. All building blocks have well described and tested authentication options to fulfill demands on data and information security. It is essential to understand that authorisation of data can essentially be carried out for each record of data in the database or file on the secured OPeNDAP server. In practice this is mostly done at certain levels of data and information. This level of authentication will be discussed with data owners and client.

Project examples

Naivasha

A very good example of a WIS including FEWS, ODK and dissemination of information is the MajiSYS developed within the Integrated Water Resource Allocation Plan of Naivasha, Kenya. FEWS is coupled to the central data management system and imports daily rainfall data from several gauges, validates the data and stores the data in a operational way. Via OGC services stations are made available in the web page. WPS services feed the viewer with information to be displayed on the forms and also return time series data to be displayed in graphs. More information on the MajiSYS methodology and project can be found at the page called Naivasha.
