# Should the ways that generate the interpolated address numbers from the known points cross other streets or not?

 3 Using housenumber interpolation is just a convenience for the mapper in a hurry. It's faster to map but less precise. In effect, what you're asking is "how much less precise can we tolerate to be ?". The answer to that question is personal, and could even differ from one editing session to the next. Personally I'd make multiple ways, as precise as possible without being too tedious. Then again, the streets I map are usually short enough and often have housenumbers assigned a bit hapazardly, so I tend to not use interpolation at all. answered 19 Sep '13, 22:55 Vincent de P... ♦ 17.1k●17●148●245 accept rate: 19% Making multiple ways should not be very tedious. However, the street signs are positioned exactly on the block corners, but the address number may or may not be very near this same corner. The sign shows the first valid address number at the time of the sign's creation, probably from post office data. In Brazil, except by the means of surveying the area, using the road signs or getting all of the actual house numbers, the information about house numbering is not public. Therefore, I believe it is much more important to have some information than no information at all!

(20 Sep '13, 13:03) MCPicoli Nobody is suggesting to put no information at all. If you have the housenumbers at each crossroad but surveying individual houses is too tedious, then use the crosroad signs and multiple ways. And yes, it can always be refined later.

 1 I would confine interpolation to one block, that is not crossing streets. answered 20 Sep '13, 09:09 gormo 2.9k●3●26●60 accept rate: 13% 1 Gormo, could you please elaborate some more on why not crossing streets? Already 20 days since I asked the question, and I have not fully decided on how to do it... (09 Oct '13, 19:43) MCPicoli
