How to map Singapore

Just did Ang Mo Kio Avenue 3, Yio Chu Kang Road and Hougang Avenue 2 crossing. I got some questions, that needs to be answered and I think it is better to document them here than in the forum since it is more a singapore then general matter.

  • Should we spell Avenue as Ave or Avenue? My vote goes to spell out the full name.
  • How do we put case in names? all lower, First name upper, all first upper or all character in upper case? I suggest All first upper.
  • How do you name and tag the short access road in e.g. the Ang Mo Kio Avenue 3, Yio Chu Kang Road and Hougang Avenue 2 crossing, I do not know how things render, so I will wait and see, I did the northern part where I named the sub roads, the lower I did not name them at all, I think the last is better, but it really depends on how small short road segments gets rendered, so I'm testing 2 different version.

Regarding the topology for the Ang Mo Kio Avenue 3, Yio Chu Kang Road and Hougang Avenue 2 crossing: I presume you will later add another one way for YCK Road. My understanding is that for proper navigation and routing, all 3 roads need to have 2 one-way roads. Furthermore, we need to include nodes at each point of interception (like the "#" character). I have just updated the junction for AMK Ave 1 and Upp Thomson Rd to reflect this. -- Singastreet 17:29, 9 January 2008 (UTC)

OK, good then we do like that, as for my question on short access road, what I meant was if they where to be named or nameless. But looking at the map fetures text it is clear that it should be named, but not higest priority. And yes I'm not finnished and will continue later, lots of tiny small roads to draw :-( Stefan talk 00:41, 10 January 2008 (UTC)

  • Just to let you know that later I will close the river mouths of Kranji and Lower Seletar Reservoirs so that the water will not leak out... :-)
    • Good we do not want any more flooding, you have to be careful :-) Stefan talk 04:56, 13 January 2008 (UTC)
    • Too late... my first attempt for Kranji Reservoir had resulted in major flooding. Luckily the water was pumped out and the lesson learned applied to Lower Seletar Reservoir (and no more flooding this time). -- Singastreet 16:42, 13 January 2008 (UTC)
  • Furthermore, for new roads, suggest that we can start incorporating the tag layer=-1 if they cross under another road. This will minimise any revision later
    • Yes, I did not know about that before and will start to put the in now, I have not done many big intersections yet. What is the difference between level=-1 and tunnel=yes? Should we use both? Stefan talk 04:56, 13 January 2008 (UTC)
    • Not sure, but "layer=-1" works and it saves some keystrokes. -- Singastreet 16:57, 13 January 2008 (UTC)

-- Singastreet 18:16, 11 January 2008 (UTC)

Some comments:

  • On coastline, I don't think we need to redo from scratch again. Instead we can touch up part by part whenever we happen to visit that particular area / portion. For example, I have touched up Pulau Tekong whilst adding the reservoir. If not, there may be many big flooding in the future.
    • Yes, I just wanted to put a note somewhere that it was not of highest quality and probably had to be improved at some time. Also if you can figure out why Palau Brani does not render please help to fix it, I can not understand what is wrong and it should have been time enough that it is rendered now. Stefan talk 01:06, 15 January 2008 (UTC)
    • Have tried but also could not render it (btw I think Pulau Brani is ok, but not Sentosa). Could it be a bug? -- Singastreet 17:24, 16 January 2008 (UTC)
      • But Sentosa renders but not Brani ... nevermind, we will figure it out sooner or later :-) Stefan talk 23:21, 16 January 2008 (UTC)
      • I have figured out why Brani or Sentosa (whatever) was not properly rendered previously. For island (i.e. natural=coastline), need to ensure that the lines / arrows are in anti-clockwise direction -- Singastreet 17:41, 21 January 2008 (UTC)
  • To minimise duplication, we may also want to have some arrangements to divide up the roads. :-)
    • I will not work that much, I think it will be very uncommon that we work on the same road. Stefan talk 01:06, 15 January 2008 (UTC)

-- Singastreet 17:45, 13 January 2008 (UTC)

Some updates:

  • I've bought a Garmin GPSmap 60CSx receiver
  • Have deleted some tracks made by johnw since it is difficult to edit them (somehow I could not delete individual segment and the system will delete the whole way instead)

-- Singastreet 16:42, 16 January 2008 (UTC)

Further updates:

  • Today is a fruitful day. Have added several roads in the city. Also linked up from city to Woodlands checkpoint, as well as extended some roads to the western side.
  • With more items added, certain parts of Singapore are getting crowded. Have to ensure that the MRT and expressway tunnels / bridges / slip roads do not collide/mix up. Therefore, I like to suggest the following layer tag be used as default (changes can be made to suit specific condition, e.g. need to use Layer=2 for ECP at Marina Bay because Layer=1 is needed for the slip roads):

- Layer=1 for all expressways
- Layer=-1 for all underground expressways
- Layer=-2 for all underground MRT tracks

  • To avoid unintended mix-up, sometimes I may have to shift some of the nodes/ways created by you. Hope that you don't mind. BTW, please feel free to adjust those created by me if necessary.

-- Singastreet 16:30, 18 January 2008 (UTC)

Yes I can see that you have been working hard! good work on downtown!!! Hum, do not agree on default layer=1 for expressways, why? Just tag as 1 when it is needed otherwise leave as blank. Agree with how you did it as Marina bay, that looks ok to me, but I do not think that e.g. ECP should be layer=1 when it is at 'normal' level. Can agree on MRT always as -2 or even -3 or -4 since it is more important to see how the roads go compared to MRT. This is a wiki, of course it is OK to adjust my work, and I will do the same for yours, don't worry. Stefan talk 03:28, 20 January 2008 (UTC)

  • No problem. We can use layer=1 and bridge=yes to represent the flyovers for the expressways (and other roads) -- Singastreet 23:05, 24 January 2008 (UTC)

Mapping Singapore.. again

Hi guys.

I'm not new to OSM but I am fairly new with the contributions. I'm currently attempting to map eastern Singapore, specifically, parts of Bedok & Pasir Ris and Simei & Tampines

Things that I need to bring up are:


-Roads leading directly to HDBs/Condos/etc that only serve that purpose.

-Dual carriageways

It would be great if once all this is settled, we could all meet up or go (individually at own pace) and map as much of Singapore with as much details as we can. Something to rival google maps!

I hope people are still here. =)

If there is no one left and people would like to join me, do reply here. I'll be watching this page. =)

Cheers. --Fusionstream 16:48, 15 August 2010 (BST)

I just got a HTC HD2 and trying out Navicomputer. Will be interested to help to map it out. Looks like a ghost town though.

- KillerKink (12 Sep 2010)

Arr... Thar be windows.. heh. Alrighty.

Anyway, just fyi, on the roads that I've done, in case you're looking for something already done:

- Those roads that lead into a HDB cluster or some very narrow roads that are used solely to service landed properties have been termed "Residential Roads (highway=residential)".

- Roads with similar uses as above except for non residential buildings are termed "Service Roads(highway=service)"

- Roads which form a loop from one part of a main road to another, and connect the main road with Service Roads or Residential Roads are termed "Tertiary Roads(highway=tertiary)"

- Other roads are "Secondary Roads(highway=secondary)" (except for next point)

- Other roads which typically have 3 or more lanes and almost exclusively are dual carriageways (divider or pseudo-divider in between directions) are "Primary Roads(highway=primary)"

HDB Buildings have:



addr:street=Tampines Street 21 (as an example)

addr:housenumber=201E (as an example)

addr:postcode=521201 (as an example | I haven't actually been able to do this due to lack of knowledge of all the post codes)

Multi Storey Carparks have:




addr:street=Tampines Street 21 (as an example)

addr:housenumber=201E (as an example)

addr:postcode=521201 (as an example | I haven't actually been able to do this due to lack of knowledge of all the post codes)

Dual Carriage Ways:

These have to be done via 2 parallel roads, both oneway streets (oneway=yes) in opposite directions. You can associate both roads into one via (ref=Simei_Road/or_your_road_name)

Hi, I'm new and wondering if this project is still active? BTW, I think there's a mapping error in one half of Lengkong Tiga. My track went off the road. I suspected GPS error at first, but it seems to agree with Google Maps. This is from Motion-X GPS. Not sure if it is really an error...

Noosnik 16:31, 24 November 2010 (UTC)

Hi everyone,

I am Alex and I will be leading a new established research group in the field of transport planning in Singapore. We intend to establish a new transport simulation for Singapore which might rely on OSM-data. We obviously would also contribute to the mapping process. Therefore, I'd like to know who is still active in the OSM-Singapore community.

erathal 14:40, 12 Decemeber 2010 (UTC)

Well I'm here. I don't check the wiki or forum much though.

@Noosnik: Edit it then? =)

--Fusionstream 05:18, 21 February 2011 (UTC)

Hi! I'm active again :-)

--Singastreet 16:04, 3 March 2011 (UTC)

Hellooow =) --Fusionstream 07:59, 24 July 2011 (BST)

Addresses in Singapore

How do we tag Singaporese addresses? I'm new in Singapore (I'm from Amsterdam, The Netherlands), and I notice there are a few aspects to addresses I'm not accustomed to. For example, this is the address of the Institute for Media Innovation, Nanyang Technological University:

Research Technology Plaza, X/Frontier block, #03-01, 50 Nanyang Drive, Singapore 637553

I would tag this as follows:

addr:housename=Research Technology Plaza (or not tag at all, as in this case it's the name of the building area)
addr:street=Nanyang Drive

However, how should we tag the "X/Frontier block" and "#03-01" parts? The first denotes the part of the building, and the second is in the form #floornumber-roomnumber.

--sybren (talk) 08:10, 17 March 2013 (UTC)

Looks about right. If it's a building, do also tag it with building=yes.

--Fusionstream (talk) 11:48, 28 September 2013 (UTC)


Should we tagged the footpath in Singapore? User:euegenpjk

Mapping bicycle paths and PCNs

A lot of people have been mapping the bike paths and PCNs in Singapore, which is awesome, but there are a lot of variations on how they are tagged.

I would like to start a discussion on how we should tag the PCNs, the new On Road Cycling Lanes and the bicycle paths.

About 70% of the PCNs are currently tagged with lcn and the 'Park Connector Network' relationship, but a lot of variation make the maps hard to use.

My proposition is:

1. National Cycle Route (ncn): 1.1 bicycle routes that cross the whole island, like the upcoming Round Island Route, or the upcoming North-South Axis;

2. Regional Cycle Route (rcn): 2.1 all official PCNs as reported by NParks or by observation. 2.2 all official 'On Road Cycling Lanes', like the ones on the Tanah Merah Coast Road.

3. Local Cycle Route (lcn): 3.1 all other bike paths not listed above

In addition, all the PCNs would be assigned the 'Park Connector Network' relationship. The On Road Cycling Lanes would get a new 'On Road Cycling Lanes' relationship.

Will add this proposition to the wiki, and contact the main historical editors.

Any thoughts?

--Sermann (talk) 11:58, 1 May 2017 (UTC)

I'm still quite a newbie to OSM, but I guess on-road cycling lanes seems like an important distinction to make from off-road ones, in terms of safety risk to bicyclists. But why distinguish official paths from "non-official" ones? --Btcprox (talk) 07:29, 5 May 2017 (UTC)

Postal Codes

I found out that not all SG addresses are searchable using postal code. Is there a way to import postal codes for addresses in SG into OSM (I doubt so but it is worth a ask here I guess)? this page says that most likely there will be copyright issue. If this can only be done manually, I am keen to do it but it will take quite a while. Just asking the community for opinion before I start. Tks! --Ocean168 (talk) 06:03, 16 July 2018 (UTC)

HDB Name/Address

Quite a number of HDB flats are tagged with Name = Block Number, with the address field left blank. When the address field is filled in with the block number, it will create duplicate display of block number such as 358(358) where 358 is the name and 358 within the () is the house number. Eg. This appears in OsmAnd app. I would propose that once the address field is filled in with the flat's block number, the now redundant block number from the Name field is deleted. --Ocean168 (talk) 12:49, 14 August 2018 (UTC)

I think that's fair. Seems like the adding of the block number in the name is a case of "tagging for the renderer", trying to get the numbers to show up in the OSM standard tiles, when the buildings aren't officially named anything. --Btcprox (talk) 11:08, 16 August 2018 (UTC)
