A Spatial Data Infrastructure dedicated to scientific research and observation of the coastal environment

International audienceAlready before the introduction of the INSPIRE European directive in May 2007, the multisite UMR LETG research laboratory of the CNRS had experience in cataloging environmental geographic information (Faucher et al., 2008; Gourmelon et al., 2009). It is thanks to this expertise as well as an involvement in various environmental and coastal observations network (3 sciences of the universe observatories and 2 workshop areas) that the LETG led the implementation of a federative and interoperable web atlas project. Indigeo, which means “to need..” is a Spatial Data Infrastructure (SDI) dedicated to scientific research and observation of the environment in the west of France. It consists of a catalog of metadata and a geo-referenced data server backed to a web portal with a viewer. The deployed solution is based on geOrchestra open-source tools (geonetwork, geoserver, openlayers ....) an initiative of géoBretagne the regional SDI of britanny, that making it interoperable with national, regional and local institutional and scientific SDI. To respond to the needs of specific scientific data visualization, the choice was made to develop an ergonomic and scalable additional viewer geoCMS. Among its original functionalities there is the support of spatio-temporal data, the display of sensor time series graphs and the ability to generate dedicated portal instances.indigeo is actually constituted of a range of 626 metadata sheets and a warehouse of 599 published information layers. According to the INSPIRE directive, this information is accessible via a digital portal http://indigeo.fr which had over 3,000 visitors since its opening in June 2013Cyril Faucher, Françoise Gourmelon, Jean-Yves Lafaye, Mathias Rouan.
