Geode — Continuous digital geologic mapping at 1:50,000 scale

This map represents the result of the cartographic homogenisation of the MAGNA geological map series (National geological mapping at 1:50,000 scale). Series that integrates 1143 maps. As a result of the long process that the historical execution of this series has entailed, 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 on the edges of leaves, coding and symbology. With the aim of correcting these problems, the GEODE PLAN was launched in 2004, which constitutes the institutional support for the generation of a continuous digital geological map at 1:50,000 scale. The PLAN integrates 19 Regional Projects linked to their corresponding geological zones. Its main objectives are three: • Provide cartographic continuity to the geological leaves of the MAGNA series within each region. • Generate a unified legend of geological units for each region. • 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.
