Roads

Road Classification

Use highway to classify the importance and usage of a way. Use tracktype to roughly classify the quality (regarding surface and smoothness conditions) of a way. To give more details on the quality, use surface and smoothness. For ways that cannot be used by cars, use either highway=path or a highway according to the importance of the way (for example highway=residential) together with a tag indicating the barriere for cars (for example width).

List of officially numbered roads

Mark all national roads as network=VN.

Help

Users who are ready to help beginners to contribute in Vietnam Mapping Project:

  • Contact capiscuas AT gmail.com if you would like to participate and don't know how to start
  • GeoGrafiker is a very experienced user from Germany. His motivation to help Vietnam Mapping Project is that he wants to go to Vietnam in November 2009. For this journey he needs the best available OSM maps. Please contact him through OSM mailing system.

Possible data sources

  • The U.S. National Geospatial-Intelligence Agency has public domain country files with basic information on placenames. Nevertheless, it contains many errors and many towns are missplaced.
  • The AsiaGPS forum contains many GPS traces from Vietnam and Asia. Please contact them to encourage them to release their data into OSM.

Bing imagery

Bing imagery is not well aligned on some parts of the country. Download GPS tracks to check for correct alignment. Until Bing fix it, you need to manually enter the offset in JOSM (right-click on Bing layer -> New offset).

Date, Region/City, and offset of observed misalignments:

  • 2013-03, Hué, offset: 0.000126;-0.0000315

Quality control

Kaart Mapping

Kaart conducts ground surveys for improvements to OSM data. A list of editors can be found on the Kaart wiki page. Current and upcoming (planned) Mapillary imagery from the Vietnam drives can be viewed here:

Tracks driven during Kaart's March 2019 ground survey in Da Nang, Vietnam

Da Nang (March, 2019)

  • Primary focus was on adding names to streets where there was no available data in OSM.
  • Most streets had a label of one format or another. There were either street signs on corners, or street names were gathered using address plaques on homes.
  • Some streets were missing names on the ground where road signs had been installed and deliberately left blank. When we saw these, they were given a tag of:
    • noname=yes AND
    • fixme=noname
  • All street signs and names include the prefix of "Đường", which was not previously entered, and which we added to each street we touched while in Da Nang.
  • Stop signs, stop lights, and general traffic control signs are not common in most areas outside of downtown Da Nang.
  • One way streets are not common in Da Nang, but were verified and added wherever we could find them. After this drive, we have full confidence in all one ways currently depicted in Da Nang proper. We took extra care while driving to ensure accuracy.
  • Most residential streets in downtown Da Nang are narrow, motorcycle-only streets. Where we encountered these streets, we drew them in and updated their tags to reflect the following tagging scheme:
    • highway=residential
    • motor_vehicle=no
    • motorcycle=yes
    • moped=yes
  • The ground survey of Da Nang was conducted by Kaart Team member Gary.

Suggested Community Edits

  • Geometry correction and addition of small, narrow roads in downtown Da Nang is heavily needed. We did our best to walk these streets and add them in where we could, but due to time constraints, could not reach the majority of these roads.
  • Tagging scheme for the aforementioned streets should follow the example given above.
  • Further name verification and addition should be continued throughout the outskirts of Da Nang.


Hanoi (Hà Nội) - April, 2019

Tracks driven during Kaart's April 2019 ground survey in Hanoi, Vietnam.
  • As with Da Nang (Đà Nẵng), our primary focus was to add road names wherever possible, as the OSM data is sparse.
  • In our time, it quickly became apparent that there are many undocumented minor roads that lead into densely populated neighborhoods with great potential for data gathering. However, these particular roads are very narrow and are not conducive for cars; on foot is perhaps the only method by which data gathering is possible.
  • We frequently encountered similarly named road segments that all belong to a specific road. For example, Phố is a prefix commonly used on many roads but is just as frequently left out.
  • Many roads that are labeled as service are actually residential but are too narrow to accommodate a car. In instances like these, we used the following tags:
    • residential:yes
    • motor_vehicle:no
    • motorcycle:yes
    • moped:yes
  • In many cases, lanes were not marked on the road surface so the interpretation of lane count will differ from editor to editor. To complicate the editing process, any Mapillary imagery taken during our data gathering will show that individual drivers do not necessarily follow the convention of “lanes”. Be cognizant of how wide a particular road appears and use your best judgement when assigning lane values.
  • A consistent naming hierarchy is used in Hanoi to document the progression of major roads into minor road. The hierarchy we observed is as follows in order of major to minor:
    • Đường
    • Ngõ
    • Ngách
    • Hẻm
  • Additionally, stop signs, traffic lights, and general traffic control signs are uncommon outside of downtown Hanoi.
  • The ground survey of Hanoi was conducted by Kaart Team members Corban, Ryan, Garrett, and Jordyn.

Suggested Community Edits

  • Further geometry edits on buildings and roadways is needed in downtown as well as rural Hanoi.
  • Many roads that lead to dense neighborhoods containing lots of potential data are best accessed on foot. Given our time constraints and emphasis on gathering major roads first, we could not allocate time for these data rich areas.
  • Though we gathered much road name data, there is still much to be gathered in and especially out of Hanoi proper.


Ho Chi Minh (June, 2019)

  • Travel is currently in the planning phase, but will occur during May or June of 2019.
