I draw address interpolation ways by making two parallel ways extending through the whole length of the street (not one way per block). I also put If a street changes name, and thus it's split into two ways with different asked 13 Dec '12, 20:05  nicolas17 |
One Answer:
The best data is data that has all housenumbers in it, so no interpolation. Of course, this isn't always feasible, and the interpolation method gives good data with less work. But, the smaller you can get those interpolation ways, the better. I would certainly split it when it's changing street names, and I would even try to split it per block (if you have that data). When a street changes names, but you keep the same interpolation way, I don't know how existing software is going to handle this, so for compatibility reasons, it would be best to split in different parts. answered 13 Dec '12, 23:25  Sanderd17 |
atm I don't even have accurate-enough information in the interpolation. For example I know that a block goes from 100 to 200, but I haven't collected the exact number of the house on the corner. If I split per block I end up with four nodes with the same number (see around node 295097394).
