Hello All,
I started large scale collection of house numbers. I'll start with
Eastern Pretoria and then expand South West until I reach Randburg. I
hope to add on average 150,000 houses per year with an accuracy /
completeness of over 50%. It is possible due to 2 pieces of
technology:
The first is a little mobile app that allows me to enter house numbers
while cycling. A typical 2 digit house number takes only 3 key
strokes.

But it's still not fast enough to collect every house number when
cycling at 20km/h. So I will need to create interpolation ways. The
fastest way of doing this will be with the help of an editor plugin
that is yet to be written:
1. You select 2 house number nodes that are on the same side of the
same road and activate the tool.
2. The tool generates a way that runs parallel to the road and
connects the nodes.
3. The tool sets the addr:interpolation tag to odd or even so that it
matches the selected house numbers.

Any volunteers to write this plugin ?

Hi Nic,
Sounds great. I haven't coded anything for JOSM yet, but am more than
willing to take a stab at it. Would the selected houses be the start and
end nodes of the way to be generated, or would they be two consecutive
nodes and the rest to be added? If it is the second one, we would need a
third node to indicate the start (or end) of the way.
A possible pitfall that I foresee is dealing with unevenly spaced or
sized lots. For example, a residential area is divided into blocks of
equal size, but in one block there are 3 houses along a way, and in the
next block only 2.
Anyway, I'll take a look so long and see what I can come up with.
Regards,
Philip
