Three candidates are available for EDA :

• The French layer which is the most detailed : BDCarthage
• The european database from the JRC : CCM
• A database based on the previous one but less detailed : ECRINs

When comparing surface layers for ECRINs and CCM for the bassin Loire-Bretagne : the CCM layer is more extended than the Ecrin Layer
