Abstract

The amount of open data available for hydrology research is continually growing and provides opportunities for new science and products. Although the existing digital infrastructures (GEOSS Portal, INSPIRE community geoportal and other initiatives) provide access to open data, many hydrologists still encounter difficulties in finding and using open data. Since the time spent on collecting and preparing data usually amounts to more than the time spent on an experiment, any improvement on finding, understanding, accessing and using open data is greatly beneficial. The Spatial Information Platform (SIP) has been developed to tackle these issues within the SWITCH-ON European funded FP7 project. The SIP has been designed as a toolbox of interconnected software components based on open standards that provide to the user all the necessary functionalities as described in the Publish-Find-Bind (PFB) pattern. In other words, this means that the SIP enables users to locate relevant and suitable data for the task they are carrying out and to access and transform it (filtering, extraction, selection, conversion, aggregation). Moreover, the SIP can be used to provide descriptive information about the data and to publish it so others can find it and use it. The SIP is based on existing open data protocols such as OGC-CSW, OGC-WMS, OpenDAP and open-source technologies such as PostgreSQL/PostGIS, GeoServer and pyCSW among others. The SIP is divided in three main user interfaces: the BYOD (Browse your open dataset) web interface, the Expert GUI tool and the Upload Data and Metadata web interface.
The BYOD (Browse Your Own Data) HTML5 client is the main entry point for end users that want to search and browse open data in the SIP. The BYOD has a map interface based on Leaflet JavaScript libraries so that the users can search more efficiently. The Expert GUI is an integrated desktop application which can be run by verified experts and members of the SWITCH-ON project only and provides full metadata editing capabilities. The web-based Open Data Registration Tool is designed to provide a user-friendly upload and metadata description interface the end users community. In conclusion, the Spatial Information Platform (SIP) provides to the hydrological science community a set of tools for better understanding and ease of use of hydrological open-data. Moreover, the SIP has been based on well-known OGC standards that will allow the connection and data harvesting from popular EU open data portals such as the GEOSS system of systems.
