Common Mistakes

Name – tag:

  • do not use only capital letters (not „KANNDANTHALLI ROAD“ but „Kanndanthalli Road“) --
  • the name-tag is only for the real name of objects not for descriptions, additional informations…
  • do not use abbreviations
  • the name in Latin English; local language name in name:ml…. ; see


  • do not map a single node for a building but a closed polygon with the tag building=yes/house
  • do not add „name=house/home/HOUSE/...“
  • buildings are normally rectangular (easy to map in JOSM)
  • do not map a building-polygon over an already existing building
  • buildings do not have shared nodes with a highways or other object (except the neighbor building)
  • highways normally do not go through a building


  • within villages/towns most highways are residential highways; only main roads with more traffic/importance are unclassified/tertiary/…
  • the nodes of a highway do not have shared nodes with other object types (exceptions : highway crossing with a railway→ level_crossing; crossing of a stream/river without bridge → ford=yes)
  • highways should always be connected to other roads (else routing is not possible)
  • prove your highway mapping by ground survey (especially if parts are not visible on Bing,ESRI,.. because of trees)
  • make as much as possible gpx-tracks and upload them
  • nearly all motorways are already mapped; do not add motorways without connection to other motorways, trunks and they are officially declared y the government!!


  • use layer=-1 only for bridges/tunnels/culverts
  • waterway=riverbank is only additionally for broad rivers; a linear way with waterway=river.. is always needed
  • do not connect river-ways to riverbank-polygons but to the confluent river
  • take care for the correct directions; water does not flow up the mountains


  • different type of landuse may not overlap : no villages inside a forest….
  • waterway=riverbank may not overlap with natural=wood…; that means divide the wood near the river in two seperate woods
  • map the landuse in small portions
  • landuse-areas do have shared nodes only with other landuse-areas
  • a farmland with „name=farmland“ is not correct
  • we do not map the personal name of the owner of a building/landuse-area…


  • Map them only if the case can not be solved without a multipolygon ( a lake in a small forest; a building with an inner courtyard..)
  • multipolygons without inner elements are useless


  • they should be mapped only with relations ( see state,district and sub-district boundaries)
  • boundaries should share nodes only with other boundaries (exception: a river declared as the boundary)
  • read the wiki for the correct admin_level
  • boundaries do not overlap with other boundaries

amenities, shops.. :

  • do not use the name-tag to describe the amenitiy, shop..
  • look in the wiki for the tags to use
  • a single node ony with a name-tag will not be rendered /visible on the map
