GEODE - Continuous digital geological mapping at scale 1:50.000

This map represents the result of the cartographic homogenisation of the MAGNA geological map series (National Geological Cartography at a scale of 1:50.000). Series that integrates 1143 maps. As a consequence of the long process involved in the historical execution of this series, there are differences between its initial and final phases, in terms of criteria for assigning geological units, level of detail, continuity of geological units and structures at the edges of sheets, coding and symbologies. With the aim of correcting these problems, the GEODE PLAN was initiated in 2004, which constitutes the institutional support for the generation of a continuous digital geological map at a scale of 1:50,000. The PLAN integrates 19 Regional Projects linked to their corresponding geological zones. Its fundamental objectives are threefold: - To provide cartographic continuity to the geological sheets of the MAGNA series within each region. - To generate a unified legend of geological units for each region. - To adapt the geological coverage to a uniform topographic base, generated specifically for the GEODE PLAN from the national topographic map 1:25000 of the IGN.
