Replay of the webinar BDLISA version 3
A third upgraded version
Set up almost 10 years ago, BDLISA is a hydrogeological reference base dividing France into hydrogeological units (geological aquifer formations, semi-permeable or impermeable). This is the cartographic base for the Water Information System (SIE). It provides a scientific framework and is also a valuable source of information for managers and decision-makers in the field of groundwater resources.
The third version, published this year, has been updated with extensive user feedback (nearly 20% of the hydrogeological units have changed since the previous version). It also takes account of the improvement work carried out in specific contexts (Armorican Massif, Massif Central).
The conference will be an opportunity to present the new features of this reference base so you can learn to use it and take part in improving the knowledge available for your region!
