From Wazeopedia

MegaMapRaid China will run from Aug. 26 through Sept. 10, 2017. Please do not make any edits in the raid area until after the raid begins. This will allow us to get good mapraid statistics.

A MegaMapRaid (MMR) is a MapRaid in which a group of international map editors join together and update a large area. Besides the benefits of a normal MapRaid, it opens up different ways of dealing with editing and navigation situations, because every country has its own specifics. It is always fun and a great learning experience to people from several backgrounds. Besides, the raiders together quickly improve the overall condition of the Waze map.

The participants will be divided into three groups, one for each section of the map. Each group will have both local and senior editors, one of which will be the group leader. Please direct all questions to your group leaders.

The raid organizers will be available across all areas for added support: asterix06 enhket orbitc


The raiders' primary mission is to improve connectivity between villages, towns and cities. this means adding segments where they are missing. Naming the segments requires language ability, so that is best left to the local editing community.

The tasks:

  • Create segments, especially those that connect villages, towns and cities to major highways
  • Verify the map for errors
  • Respond to Update Requests (URs)
  • Respond to Place Update Requests (PURs)
  • Have fun!



Each raider will be asked to focus on the area for their group primarily but will be able to access other areas, if needed.

Important / Mapraid guidelines

Please read the entire MapRaid wiki. If you are still uncertain what to do about something you see on the map, please ask your group leader Thank You for your help with the map.

Non-Chinese-speaking raiders

There are numerous challenges that limit what can be done for those who don't speak or read Chinese. Google Street View is not available in China, which removes one usable source of data for labeling street segments and Places.

As a result, raiders should focus on adding roads to enable routing in more areas. The GPS layer can help confirm streets as drivable, if vehicles are not visible in the satellite imagery.

In addition, responding to URs will help provide more feedback on possible errors. Solve the as many as possible based on report GPS and navigation data. A query statement in Chinese may be provided by group leaders — "Please explain the problem you had in driving with Waze" — and any replies can be saved to a sheet for possible translation and action later.

Any Place Update Requests also can be moderated for appropriate photos.


There are many aspects when we deal with connectivity. In the end, we all want drive to our destination in the fastest way. Therefore, we need roads. No roads, no navigation. These roads need to be connected, so there is a route possible from one to the other. The more experienced you get, the more you can do to improve connectivity, like using road types, naming, and corners, to improve routing and navigation instructions.

The first sub goal of connectivity is adding drivable roads. Roads are build up from segments, which need to be connected to function correctly. Always check if a junction is working correctly. Check the angles to ensure the driver gets appropriate (turn/keep) instructions.

A rough guideline to using road types

In some cases, there are brand new roads that do not yet have a name visible to drivers. Or the person who used the pave option did not leave a note for the name of the new road. In these cases, it is OK to leave the name of the road blank by marking "none" for the Street and City fields in the editor. But please make sure to choose the proper road type and confirm any other details you can to ensure the road appears correctly on the client app and enable routing.

  • The main roads in a district or town should at least be set to Primary Street.
  • If segments will be used for through traffic or for longer distances connecting districts or towns, they should at least be mH (Minor Highway)
  • Main interconnecting roads with fast traffic should ar least be MH (Major Highway)

Always make sure a road is at least connected to a same level of road type or higher. Thus, Waze should be able to route from primary to primary (or higher), from minor to minor (or higher), from major to major (or higher), and from Freeway to Freeway. Another way of explaining this, is that you should be able to continuously drive on the same or higher type of segments for the routing engine to use that road type in the calculations.

This means we need to sometimes make small roads mH, for the possibility of calculating long distance routing. Please post a question if anything is unclear.

Adding Roads

If you notice any roads on the satellite layer that have not been added to the WME map, please first confirm that they exist before adding them. Make sure the road is complete, drivable, and is connected to the rest of the road network. Some clues you can use are:

  • GPS layer showing Wazers are driving on the road.
  • Satellite View on the road, showing it is in use
  • Information from local drivers who have been there (this can be you, if you have been there).

Some roads are partially completed. Before extending the road, make sure the "new" section is completed,drivable, and connected. If you are unsure about roads that were created by another editor before the mapraid, DO NOT delete them without instructions from a local host.

It can help to do a visual check to ensure roads are suitable for driving rather than for pedestrians or bicycles only. Perhaps this You can turn off the Roads layer to have a proper view on the Satellite Imagery. If the roads appear too narrow for vehicles and if GPS shows no activity, you should reconsider adding the new roads.

Naming segments

  • For City, we use Chinese /English.
  • For Street, we use Chinese only on Primary name, English on Alternative name.

For those who cannot write or read Chinese, please leave the Primary name blank and just put English on Alternative name. In order to do this, you must first put anything in the Primary name and press 'Apply'. Then enter the English name into the Alt field and press 'Apply'. Then edit the Primary name again and click the box "None" for the street field and press 'Apply. The Alternative name will remain for the segment while "No name" is set for the Primary field.

City name

As you know we do not have 'State' field for China, I am thinking just simply to put 'District Level' format, i.e. the Province name and Prefecture level city names are omitted

See spreadsheet for a list of divisions to use: Administrative Divisions of China for Waze Map

In case of duplication in district level, then we will put 'District Level, Prefecture Level City' format. For example:

For normal situation: District Level, e.g. 顺德 Shunde

For duplication situation: District Level, Prefecture Level City, e.g 佛山顺德 Shunde, Foshan

We will use Discord for communication. Use this link to join: There will be a MegaMapRaid general channel and also a channel for each raid group. If you have trouble joining, please reach out to one of the MapRaid organizers.

WME chat can also be used. The WME Chat addon is recommended.

Mapraid edit lists

Spreadsheets and forms are being used to streamline management of various group efforts and track important edits. Below you can find links to use these these forms, sheets, and see the lists.

MapRaid Promotions

Some editors really let their bright side out, and let their community skills shine. This is even more evident in a concerted group effort with high-density editing like a MapRaid!. Editors of all ranks working closely with each other and the Champs, really lets us everyone get to know each other, and allows certain editors to be recognized for their skills and effort.

When the Champs see someone consistently editing well, interacting well with the community, and knowledgeable of the various details from the Wiki, they can issue promotions. This can be anything from the size of a managed area, to a rank increase, or even a new role.

Watch here for results of promotions during and after the raid.
