Hello, I do suggest that Penang can be out of this list. FYI, most place in Penang already named by Kaart last year (especially in Penang Island west coast, and some major cities in mainland). While for the rural area mostly they dont have a good Karta View coverage.

For, Klang Valley it should be include kuala Langat and Sepang district, lots of new development area they have some KartaView imagery.

Kota Kinabalu and Johor Bahru is ok.

I do suggest IPOH (Kinta District) to add into this list, I can easily find many KartaView imagery in Ipoh (even more than Penang), but need someone to input.

And Grab maybe can consider to use MAPILLARY as a source while adding name. Please add source in the meta data for street when adding new names, so that other mappers can do checkup. (We frequently do that)

FYI, there are lots of 360 Mapillary imagery around Alor Gajah and Jasin, Melaka. So I do suggest thoses place to be added in your team liast also if can.

Hello, so far lots of mistake had been discovered by me (2 out of 3 are problematic), please be careful so that local mapper effort would not be ruined. (and please use a hashtag will editing) .

Hello MASangys, Thank you for sharing your feedback. We highly appreciate your suggestions and the community involvement in OSM. We are glad to know that Penang already has most of the street names mapped. It’ll help reduce our efforts in the city. Thank you for helping us with your recommendations on the cities, it’s really appreciated and will be of great help.

As you suggested, we will add sources in the metadata to help mappers verify the information from our side. We work closely with the team on these edits and ensure the quality is maintained. Could you please share the edits that you mentioned in the comment? It’ll help us understand and improve our processes as well as correct them from our end. Please let us know if there is any other feedback from your side. Thank you again for the feedback and suggestions.

Happy Mapping!

Hello.

I have set up an OsmCha filter for my own reference. Based on yesterday's edits, up until 11.59pm local time, from 33-34 changesets, there are roughly 16 of them with problems, which had been pointed through changeset discussions.

Errors are not limited to:

  1. Duplicated highway names. Some existing highway (with such names) are already there on the map, usually highways on the higher highway classifications (highway=primary, highway=secondary, highway=tertiary or highway=unclassified). These can be found on the opposite side of a building, or probably located >500 m away; from the supposedly "unnamed" streets.

  2. Related to the first point above, highways with bottom-tier highway classifications (e.g. highway=service) sometimes do not have names. I may not live around (or happened not to be able to drop a visit to) Klang Valley at the time being, but from experience living quite close to the area from 2008-2010, "it checks out". So, naming such less significant highways, for me, is actually equivalent to raising a red flag.

  3. Again, this could relate to the above two points. Misinterpretation of street signs. You may refer to Wikipedia for some examples of typical street name signs. Some directional signs are mistakenly inferred as street name signs. Different areas in the Klang Valley, under different local councils, have different street name designs.

Suggestions:

  1. It probably makes validation way easier if changeset comments from your team include:

e.g. Mapping Missing Street Name in Malaysia, #grab Added Jalan XYZ https://kartaview.org/details/21343/56734

  1. Hopefully any prior changeset discussions pointing out less than ideal map data, have replies to indicate that problems have been fixed in another changeset.

  2. Language barrier do exist, do let the Malaysian community mappers and/or the Malaysian Grab Map Ops Team know about it.

Most of the problem already stated by the mapper above. BTW, after this please map properly in those there region in Malaysia, if low quality input still persist, I think it is better for the team to TERMINATE this task since it brings more bans than boons to the local community.

Hi again. I would like to point out another inaccuracy in mapping street names. In this case, a highway was mis-named after a hydrological feature. A sign indicating the name of a river (blue in colour) is indeed erected by the Department of Irrigation and Drainage.

Closer inspection of likely street level panorama, indicates the above logo which represents the related department (Department of Irrigation and Drainage). Also, Sungai in the Malay language is a river.

Hi @AkuAnakTimur, Thanks for reviewing our team edits. We are reviewing our old edits with word "Sungai" and remove them as soon. Going forward, we will take necessary precautions to avoid such instances.
