Description

The BD LISA (Boundaries of Aquifer Systems Database) repository currently in circulation is version 3. This repository comprises the following spatial datasets: - Level 3 hydrogeological entities (local); - Elementary polygons delimiting each single stack of hydrogeological entities; - Karst areas, areas characterized as being of karst environment or feeding karst sources; - Movable alterite areas, extension polygons of areas where the presence of movable altered geological formations (saprolite) has been identified or is assumed. As well as additional information tables: - The multi-scale table comprising all the hydrogeological entities mapped (levels 1, 2 and 3) - The genealogy table summarizing the changes made between version 2 and version 3 of the BDLISA. - The table of piles of hydrogeological entities that associates each elementary polygon with the level 3 hydrogeological entities present under this polygon, by ordering them vertically. - The lithology table that associates each hydrogeological entity with the rock nature or natures that characterize it.
