South Korea | Data Improvements

[SyedNasrulla-TomTom]

Project description

Goal

Improving the map quality in South Korea (officially the Republic of Korea) by sharing tasks that can help fix data errors and/or add certain kinds of features.

How to participate

Anyone is welcome to contribute to this project by participating in our MapRoulette challenges. Here is the extended documentation for using MR. Note that sometimes additional instructions are provided within the challenges. We also strongly encourage you to follow good practices, editing standards, and the South Korea mapping guide.

Here is the current set of challenges.

Challenges

Active Challenges

Fix Incorrect Highway Junctions

Identify and fix if needed, incorrect or imprecisely located junctions.

• South Korea - Fix Incorrect Highway Junctions

Fix Intersecting Buildings

Identify and fix, if needed, situations where a building intersects with another building at the same layer.

• 한국 - 겹쳐 있는 건물 고치기 | South Korea - Fix Intersecting Buildings

Fix Building & Highway Intersections

Identify and fix, if needed, cases where a way with tag highway* intersects with a building.

• 한국 - 건물 및 고속도로 교차로 수정 | South Korea - Fix Building & Highway intersections

Fix Incorrect Junctions on Roundabouts

Identify and fix cases where two or more highways are connected to the same node on a roundabout. 

• South Korea - Fix Incorrect Junctions on Roundabouts

Fix Spiky Buildings

Examine and fix the set of potentially erroneous buildings that we’ve identified. Visit the locations on the map and assess whether the building shapes seem inaccurate.

• South Korea - Fix Spiky Buildings

• Add missing highways in South Korea. Leads generated by spatial comparison of TomTom's in-house road centerlines with the OSM road network and identified missing way locations.
  South Korea - Add Highways

• Add highways in South Korea. Leads generated by spatial comparison of TomTom's in-house road centerlines with the OSM road network and identified missing highway locations.

Fix Inconsistent Highway Intersections

Identify and fix cases where highways intersect without a common node.

• 한국 - 엇갈리는 길 속성 수정 | South Korea - Fix Inconsistent Highway Intersections

Connect Isolated Highways

These are tasks comprising of situations when a way with tag highway=* is not connected to the rest of the road network. Analyze and, if needed, connect the way to another way with tag highway=*.

Edits based on Map Feedback

We will make improvements to OSM based on user feedback submitted for the TomTom map after comparing and ensuring that it is also valid for OSM.

• Highways

  • Adding or correcting highways
  • Adding or correcting link roads
  • Adding or adjusting bridges, tunnels, layers, or relations
  • Adding or updating lanes and related properties
  • Adding or updating traffic signs
  • Adding or updating access barriers
  • Adding or updating turn restrictions

• Addresses

  • Adding or correcting addresses
  • Updating the position of address nodes, usually when an object has multiple addresses
  • Adding or correcting names of ways

• POIs (Points of Interest)

  • Adding POIs
  • Correcting POI locations
  • Adding or correcting POI information
  • Resolving POI-land use discrepancies
  • Handling POI closures

• Land use

  • Adding land use
  • Modifying existing land use extent

• Buildings

  • Adding buildings
  • Updating building type
  • Adjusting building shape

• Water

  • Adding or realigning rivers, streams, and lakes.

• Railways

  • Adding railway tracks
  • Realigning railways tracks
  • Adding or adjusting railway infrastructure tags such as bridges, tunnels, level crossings
