There's no metadata for the zip code layer I have, so I'm assuming it's old and was wondering about updates.
Do you know of any good papers/resources on the use of zip codes for geocoding, or any good articles on the finer points of geocoding? Manuals tell you how things work in ideal situations, but it ain't a perfect world.
If zip is a poor choice for geocoding by zone, what's a better one? Lots of people (and of course "lots of people" can certainly be, and frequently are, wrong) seem to think zip is the best filter we have for identifying streets.
I'm a bit disappointed in the geocoding algorithms I've "seen" (used) so far. Ideally, I'd like to use multiple layers (GDT, locally collected centerline data, city limits, zip, etc) and have more conditional control over what's going on; e.g., make a zip match "nice to have but not a deal-breaker", to use multiple road reference layers looking for the best match, etc, etc.
I've been told there's more flexibility / user-customization with geocoding in ArcGIS 9.0 (e.g. "fallback" geocoding where you can, in fact, use multiple layers). Here's hoping it works (well).
