In Salt Lake City, South Temple is 0 N/S and Main Street is 0 E/W.
Though the Avenues District changes the normal grid layout.
While Ogden (Utah) is laid out in a grid, it is somewhat different. In
Ogden, Wall Avenue is 100 E/W and North Street is 100 N/S. Also, east
and south direction prefixes are assumed if none is given. So "3725
Washington" is really "3725 South Washington Boulevard", and "350 25th"
is "350 East 25th Street". If/when you run your script on Ogden (which
I'd like), you'll have to take this directional assumption into account.
However, we come to the problem of tagging as the street signs say (as
the wiki says with abbreviations expanded), or tagging for address
look-up (which I've only seen Cloud Made make available). When tagging
for alternate names, do we use "name", "name_1", "name_2", "name_3",
etc, or "name", "alt_name".
Note: Some streets that I've corrected tags on legitimately have six
name tags. For instance: "Washington Boulevard", "South Washington
Boulevard", "400 East", "South 400 East", "400 East Street", "South 400
East Street", "US-89", though the last one I've put in the "ref" tag.
(However, it would be legitimate to give an address like "3750 South
US-89" and it would get there. When US-89 splits off from Washington
Boulevard, it is fully spelled out as "United States Highway 89".) If
you don't want all of the variations put in some sort of "name" tag,
then develop a standard way of conveying the same information.
