OpenStreetMap
As promised I have completed the buildings around my estate. quite disappointed with the lack of participation in Singapore mapping especially among the Locals. Although the most obvious roads and buildings are up, we should continue to value add by increasing the amount of details available on the maps. I wish I could clone ten of me and probably could increase the amount of detail on the Singapore map by 100 percent in a week. Well enough said, Happy mapping to all!

Welcome to OpenStreetMap.
I would be happy to trace some buildings in your area to save you time in the mapping process if it means you would be able to ground survey to get addresses and street names and such.
If you are the only local mapper there your time would be much better spent collecting data on the ground with something like walking papers or by using audio mapping to collect the information on the ground that is not available in the satellite imagery.
I might trace a few today anyway, but if you would be interested in working together on this I could trace quite a few for you to gather address, POI, and street name data on the ground. Let me know if you would like to collaborate like this. The on the ground information is really the most useful to the project, since anyone, anywhere can trace imagery but only local people can gather information on the ground.

Actually, I have had a look at the area where you are working and I don’t know if I can split up the buildings like you are doing. Since almost all of them seem to have more than one address it would be hard for me to trace them and know where to split them for different addresses. The work you are doing looks good and I don’t know if I would be able to contribute as much as I initially thought.
One thing you might be able to do that would save some time is to draw just a single building=yes for each whole physical building, and then put the individual addresses as separate nodes inside the building. The nodes can also be part of the outline of the building, but have individual addresses on different nodes. These can additionally be marked with building=entrance so you know where the door is.
The way you are doing it currently though is also acceptable. As with many things in OpenStreetMap we have more than one accepted way of doing them and whichever one works best for the area you are working in is the one that gets used.
