The new LaMMA Open Data platform (http://dati.lamma.toscana.it) allows data download related to information delivered / managed by the Consortium, encouraging the reuse both at technical and legal level. At the moment the Database is a main collection of more than 200 weather forecast layers, together with other basic geospatial layers (NDVI, LandCoverChangeFlows, Landslides, Natural Risk Zones), that are in continuous updating. LaMMA open data platform integrates in a harmonised interface, most of the spatial dataset already available through the LaMMA geoportal (http://geoportale.lamma.rete.toscana.it/MapStore/public/), making them available for a direct download with a specific licence of use.
