MDM: Alert-C-lists

Some data types from the Mobility Data Marketplace (MDM) use the so-called ALERT-C or LCL list for georeferencing. It is a table that defines important nodes on the German road network across Germany. These are primarily junctions, rest areas and motorway intersections on German motorways, but also individual important points on the downstream road network as well as points in cities. The current table version is 18.0, and in addition, previous versions are often used (compare corresponding XML attributes). All table versions are provided. As a simplification, however, it should also be possible to work only with the latest version 18.0, since the tables are continuously updated according to the road network, but the assigned codes do not change as a rule (with the exception of road transfers etc.). The data can be obtained permanently after registration via the MDM (http://www.mdm-portal.de). Alternative data access has been opened at an event organised by the Federal Ministry of Transport and Digital Infrastructure (BMVI), the 3 rd BMVI Data Run. Until at least February 2020, they are additionally available without registration under the specified link.
