Task Setup

Set imagery offset

  • Add the Japan GSI Satellite layer
  • In areas without GSI coverage, match Bing imagery to Strava GPS using offset
  • In areas with no GSI or Strava coverage, set Bing offset to 0,0

Add filter

  • Create a new JOSM filter to hide non highway data boundary: | leisure: | landuse: | waterway: | sport: |amenity: | natural:|building: | admin_level: | power: | place: | type:relation | aeroway:

Add Map paint style

  • From JOSM Map settings, add a new map paint style with url https://raw.githubusercontent.com/mapbox/mapping/master/JOSM/data-qa.mapcss to highlight roads with no names
