Draw entrance letters and markers along the normal of the building edge.

• Load new tiles when panning
  • Custom, broken code
  • Custom, working code

  ---

  • Load tiles with deck.gl
• Tile source
  • Highway-only Routable Tiles
  • New Building Tiles locally
  • New Building Tiles at tile.olmap.org
  • New Routable Tiles (buildings and their entrances included, live update)

  ---

  • Include orphan entrances in Routable Tiles
  • QA Tiles (zoom 12)
  • Custom QA Tiles (zoom 14, non-simplified entrance nodes)
• Data interpretation
  • Assume that the housenumber is in the entrance node

  ---

  • Show all addresses of the building in the entrance popup
  • Copy housenumber from building to entrance
  • Analyse the addressing scheme to avoid repetition and mistakes (multi-address buildings)
• Entrance geometry algorithm
  • Use the angle of the path
  • Use the normal of the building (angle at entrance)

  ---

  • Calculate angles with Turf.js
  • Find the related building edge for orphan entrance nodes
• Visual appearance
  • Label visual distance independent of zoom level
  • Label centered
  • Try smaller font size
  • Hide when zoom level too small
  • Label anchored according to the angle
  • Include housenumber in label

  ---

  • Show entrance circles on small zoom levels
  • Dynamic label layout to avoid overlap
  • Halo of one label should overlap other labels
