Hi, Andrea: Thank you for your dedication to this interesting address data import.
I have opened the already merged osm file [1]. I think the quality of the data is really good in general in what respects to the location of the nodes, although some of them seem to lie over the road they belong too [2]. I don't see that a big concern, as they are quite rare, and moreover this could be due to a not well aligned Bing imagery. But what I see a serious concern is the big number of groups of addresses of the kind 4, 4a, 4b, 4c... Let's see, as an example, this image in Via Giovanni Crestani: [3] There we can see one building with the addr:housenumber=4 on it, but then a row of 17 addr:housenumber that range from 4a up to 4t, that are surrounding the house, some of them stretching quite far from it, nearer to the house 6 and 19 than to the 4. The same happens with numbers 6, 17, 19, 21 and 30 in this example only. Moreover, node number 8 doesn't exist in the group of 9 nodes that go from 8a up to 8i. My opinion is that these nodes should be replaced by only one. In the case of the groups of 4, 6, 17, 21 and 30 I would ignore (not import) all the nodes with letter, so keeping only the node addr:housenumber=4 , 6, etc., and in the cases like the 8, I would create a new addr:housenumber=8 as the centroid of the nodes 8a, 8b... 8i. This is a quick idea, but there may be smarter ones to deal with this. What do you think? Cheers, Rafael.
