Salam, biar betul ada papan tanda Jalan Masjid kat situ.

Papan tanda nama Jalan Kodiang kat lampu isyarat tengah pekan ada lah.

So... apparently it's the Setiawangsa Pantai Expressway. Using JOSM and am not a KL local, so I really don't have idea this is somewhere near Setiawangsa.

Hi @pitscheplatsch,

We don't have district boundaries for Perak yet, but I'll treat Muallim as a full fledged district.

Same as Pokok Sena in Kedah. It's a "subdistrict" too. But it has its own Pejabat Tanah and the likes.

Two district ("county") boundary relations was found incomplete as they were, and will be rectified in future import uploads.

Mukim boundaries... why not? Penang is the first state to 'open' it, compared to the rest of the country.

PEGIS people might look forward to actually share geodata, but, yeah. We need contacts first.

Awwww shucks, PEGIS has updated their page. Now I cannot see contact details anymore.

Should have passed this information to you wayyyy earlier.

Hello.

Any chance you can provide the source of reference to make edits to this particular boundary?

I have no idea (Queensbay and adjacent areas). You may adjust the boundaries accordingly to your local knowledge.

Most state boundaries in our country follows natural features (rivers and peaks usually). Rivers can change course with time.

There may be an exact definition for that, and Sinar Project's copy is definitely based on an older data. So it probably explains why it looks very windy.

I guess more research is needed but again, you need a better, open and free source for that. But you could spend some time to edit so that it matched the common knowledge.

Hopefully issues are rectified following these changesets:

changeset/67967636
changeset/67967665
changeset/67967782

Okay, post-import reflection: 100+ conflicts this time. Apparently someone has tied a boundary node to waterways quite recently, although a cleanup process was done earlier.

My first import: please let me know if there are errors so that it could be rectified as soon as possible.

Hello, welcome to OpenStreetMap!

There's no need to include height information for peaks - the name field is for names of features only.

Don't need to tag highway exits. Because exit means you're going out from the expressways to enter another road.

You would eventually come back into the expressways from any R&Rs.
