Rules for automatically importing as much as possible:


Contents

automatic import

Identifying the 2 nodes (one for each direction) of a motorway-junction for a motorway-junction in the LCL should be easy as there are at all times 2 such nodes in OSM and they are the only ones in close proximity to the point from the LCL.

Rules for Roads

Roads are imported first

For roads with a roadnumber of the kind "A[0-9]*" we can find the corresponding relation by doing:

For roads with a roadnumber of the kind "B[0-9]*" or "B[0-9]*a" or "B[0-9]R" we can find the corresponding relation by doing:

For roads with a roadnumber of the kind "L[0-9]*", "S[0-9]*", "K [A-Z]*[0-9]*" ([A-Z]*[0-9]*=licence plate), "G[A-Zo0-9 ]*" we can find the corresponding relation by doing:

See also: 


 foreach(road having road.already_imported=false) {
   relation rel = find(RELATION, ref=road.ROADNUMBER)
   if (rel = null) {
      rel = buildRelation(road.ROADNUMBER, find(WAY, ref=road.ROADNUMBER))
   }
   // matching start, end and via are NOT checked

   foreach(way in rel with role="") {
      foreach(segment in road.segments) {
         find_and_tag_segment(rel, segment);
      }
      tag_road(road, rel);
      road.already_imported=true;
   }
 }

Rules for Segments

Segments are imported second. (Thus only segments not belonging to a roads are tagged this way)

For segments with a roadnumber of the kind "A[0-9]*" we can find the corresponding relation by doing:

For segments with a roadnumber of the kind "B[0-9]*" or "B[0-9]*a" we can find the corresponding relation by doing:

For segments with a roadnumber of the kind "L[0-9]*", "S[0-9]*", "K[A-Z0-9 ]*" we can find the corresponding relation by doing: 


 foreach(segment having segment.already_imported=false) {
   relation rel = find(RELATIION, segment.ROADNUMBER)
   if (rel != null) {
      find_and_tag_segment(rel, segment)
   }
 }
 foreach(segment having segment.already_imported=false) {
    find_and_tag_segment(find(WAY, ref=road.ROADNUMBER), segment)
 }

 find_and_tag_segment(Relation rel, segment) {
    find_and_tag_segment(rel.getMembers(WAY, role=""), segment)
 }

 find_and_tag_segment(Way[] ways, segment) {
    Node[] start = findNode(ways, segment.points[0],          getPOIAttributes(segment.points[0]))
    Node[] end   = findNode(ways, segment.points[last],       getPOIAttributes(segment.points[last]))
    Node[][] via = findNode(ways, segment.points[1..last-1], ([etPOIAttributes(segment.points[1..last-1]]))

    Route forward = findRoute(start, end, via);
    Route revere = findRoute(end, start, via);
    if (forward != null && revere != null) {
        if (forward == reverse) {
           tag_segment(road, rel);
           foreach(point in segment.points) {
               tag_point(forward.findNode(point, getPOIAttributes(point)));
           }
        } else {
           tag_segment(road, rel, "direction=forward");
           foreach(point in segment.points) {
               tag_point(forward.findNode(point, getPOIAttributes(point), "direction=forward"));
           }

           tag_segment(road, rel, "direction=reverse");
           foreach(point in segment.points) {
               tag_point(reverse.findNode(point, getPOIAttributes(point), "direction=reverse"));
           }
        }
        
        segment.already_imported=true;
    }
 }


If we find such a relation:

The resulting relations neeed to be checked to:

Rules for Points

points are imported last. (Thus only points not belonging to a segment are tagged this way) 

 foreach(Point having point.already_imported=false) {
   Node node = findNearestNode(point.location, and("has ways with highway=*", getPOIAttributes(point)))
   if (node == null) {
      node = new Node(point.location, getPOIAttributes(point));
   }
   tag_node(node);
   point.already_imported=true;
 }

 getPOIAttributes(point) {
   if (point.class=3 && point.subclass=11) {
      return "amenity=fuel";
   }
   ...
 }


Rules for Areas

TODO

type/subtype-codes from the LCL

These are the codes and subcodes applied to LCL-locations for Germany. Where known their mapping to OSM-tags has been added.


type/subtype-codes in actual usage

This short analysis was only done on the LCL of Germany. Other countries may use other types and subtypes.
