"Is the parcel in the geographical bounds of the city name entered?" The "city name" on an address isn't really a "city". SFO's address is "San Francisco, CA", but is not within SF city limits. Queens NY addresses have "cities" that are just neighborhoods. Applying any kind of logic to addresses will just be a minefield.

There’s also no particular reason to expect that an address corresponds to exactly one parcel or that any given parcel has an address at all or that any given parcel has at most one address.

I feel like Google Maps experienced a serious regression a few months ago.

Before that, it would give reasonable mass transit directions in San Francisco. After that, it would always use a bus to go even 1 block to BART, giving drastically inflated transit times.

> it’s probably not feasible for a global product like Google Maps to understand and encode every regional system Does it have to encode them all? Why not start out with one then at least Google Maps is a little better for some. Besides that, how many systems could there be? There are only something like 10,000 cities on the planet. That sounds like the kind of task Google is built to handle.

Wait what? I live in a small country of ~2mio pop, and we have approximately 6000 settlements with streets and street addresses and many different standards of numberings, depending on many reason, mostly historic. Technically yes, a few thousand systems could be programmed into some google processing engine, but you'd have to manually classify every road to set the correct system, and even there, you'd never know wh…

Your "Cucumber street" is exactly like Germany works, as far as I can tell, including the even/odd split, and the a/b/c/d... when inserting new houses, or separate building sections. (I've seen as far as "h" in one extreme case, but I think after "d" becomes pretty uncommon.)

Was that intentional, or just neat coincidence?

I skimmed and I think that's missing That a building|property will have only one address . Sometimes (eg: rural Australia) property addresses are updated from an older numbered lot based system (that goes astray when properties are subdivided and infill houses appear) to a system that numbers houses by driveway distance from last major intersection. For five or ten years a house can be recieving mail or be on the rec…

I think this idea that a building/property can have more than one address can happen in the United States too. The way I see it, it is because a ZIP code can be associated with a list of cities that are categorized as “recommended city name”, “other city names recognized for addresses in this zip code” and “city names to avoid”. [1] So as an example, if you use the UPSP Cities by ZIP Code to research 77005 and you wo…

This happens in metro areas quite frequently. I used to live in a suburb of Atlanta that had a valid address in "Atlanta, GA" and "Suburb, GA" - which was a common annoyance when using delivery apps or service area locating systems as which address was considered "valid" often changed depending on the provider of their mapping API.

The building in that example does have only one address. The old address is not valid any more. People just accept the erroneous use of the old address for the sake of expediency.

It has at least two official addresses each with a [time frame] of official validity.

When merging records the old address, no longer valid with the local land management agency, still appears on old notices and on current state and or federal records (as land naming agencies are layered in some locales with changes taking time to perculate).

The old address is "the correct address" in the context of birth records, old newspaper articles, last years tax records, etc.

You're technically pedantically correct .. but in a manner that's moot when faced with the realities of day to day day reconciliation of meaning of text on an envelope or document.

Ha, I was in charge of data quality for Google Maps going on 15 years ago. Addresses were hard then, and I'm sure they're hard now. Alas, Google didn't want to invest in keeping this data high quality — a fact to which I actually owe my first promotion at the company (since taking over Maps data quality was a job that nobody else particularly wanted — nor did they want to move to Seattle, where Google wanted the team — but it still gave a lot of room for impact).

Sometimes I dream of going back, but the culture has changed too much (and not for the better, I hear).

hundreds of people in my city-county really think they live in a city in the next county over just because of the "city" label on their zip code

In the logistics industry the commonly held wisdom is that there really isn't any accepted system for "how street addresses work". Different countries have completely different systems, and even within a country there are often many different conventions. The thing that really matters in delivery is whether the address on the consignment has enough information for an operator to complete the next leg. By the time an…

I believe that there is no accepted global system for "how street addresses work", but there has to be a better solution then a business owner reaching out to a friend's cousin to try to get a serious problem fixed. If my fixes had been published in the promised 24 hours then this blog post would not have been written but after two weeks this is the best idea I could come up with. I think it is practical for Google M…

The friend's cousin did what they could have done themselves, use the feedback tool.

Google Maps decided my driveway is a road, and also gave it a (non-existent) name. I have attempted to update this information, but Google just rejects my suggestions as "not accepted". So we now regularly get people driving down here or trying to park, when it's actually just a one-lane driveway.
