This is a proposal for renderer / API hint relations.

Problem: Large areas may not be rendered if the area is surrounding but not touching the requested bounding box. [example]

proposed Solution: Create a "hint" relation and adapt API or renderer!


Key Value Discussion
type hint defines the type of the relations


Way or Node Role Recurrence? Discussion
node pointer 1+ hint node(s): one inside every Z12 tile not rendered correctly
area target 1 the area the hint is pointing at


  • adapt renderer to load referenced way in preprocessing and merge it into data file or
  • adapt API to include the referenced way in output.
