[talk-au] Missing post code boundaries?

[John Smith]

Including only areas AusPost considers 'Delivery Area' there is 2,623
postcodes, we have osm files for 2,507.

The following is a list of postcode areas considered Delivery Area by
AusPost, but we have no osm file for:

0829, 0846, 0853, 2308, 2309, 2398, 2649, 2661, 2678, 2769, 2899,
3063, 3237, 3254, 3267, 3273, 3309, 3329, 3374, 3378, 3385, 3415,
3430, 3432, 3488, 3489, 3506, 3565, 3572, 3576, 3583, 3596, 3607,
3617, 3663, 3704, 3708, 3715, 3718, 3751, 3755, 3760, 3762, 3864,
3873, 3893, 3903, 3957, 3967, 3979, 3990, 4353, 4372, 4375, 4376,
4378, 4384, 4406, 4461, 4471, 4479, 4611, 4697, 4704, 5139, 5150,
5220, 5263, 5273, 5310, 5414, 5455, 5493, 5630, 5651, 5660, 6077,
6078, 6079, 6180, 6181, 6182, 6209, 6211, 6223, 6240, 6243, 6252,
6313, 6327, 6351, 6357, 6384, 6393, 6403, 6412, 6413, 6414, 6419,
6422, 6424, 6428, 6446, 6447, 6452, 6466, 6467, 6480, 6504, 6506,
6509, 6512, 6564, 6571, 6574, 6605, 6613, 6614, 6625, 6628, 6631,
6632, 6639, 6712, 6733, 6762, 7119, 7139, 7151, 7174, 7175, 7176,
7183, 7187, 7257, 2623

We can probably cheat a little here. By extracting locality names from
AusPost's CSV file we can then match against place markers in the
database. We should also be able to use existing postcode boundaries
of adjacent postcodes to guesstimate the actual boundary for the
missing postcodes.

However I'm not sure if we can do this legally, as the information
would be derived from AusPost's data which has some pretty onerous
restrictions.

This isn't an immediate issue since there is over 1,500 post codes we
do have shape files for that still need to be added to OSM, we'd need
to do this before we could extrapolate missing post code boundaries.
