The “Plan4all” project, financed by the eContentplus Programme, has investigated the theme of the interoperability of geographic data related to spatial planning. U-Space has taken care of the activities related to the interoperability of data, metadata and web services of the Region of Latium (project partner). In particular, as regards metadata, U-Space has published a metadata catalogue regarding the Region’s Land Cover Map and the Regional Landscape Plan. U-Space has also worked on the communication activities, designing informative leaflets and posters, and a final publication illustrating the outcomes of the project.
