Comment(by robe):
If Brian's (dbb) comment is right that Tiger always does this then Mike
your solution would work. Brian, how sure are you about this. I haven't
been paying attention myself.
We could at least get less squishing if we assume it's the case and then
cut as a function of ratio of range to length of street or something like
that except when the user does ask for an address that is at the end.
At any rate I think your other idea of shortening the string length we
consider so addresses at the end don't flush at the end of the street is a
good idea.
As far as comparison's. I think MapQuest is based on nominatum so the
fact they produce similar answers is no surprise. I suspect both Google
and Bing are using more than interpolation and they are considering real
addresses in there calculations, so their data is just better - presumably
navteq based.
Yes nominatim is what I was thinking about but didn't like it because it
seems to have too many web servicey gooey dependencies and for my needs --
which is mostly datawarehouse stuff, I Ideally need everything to run in
the database and be self-contained (not so many moving parts) like needing
a web server component.
