POI Confirmation & Cloud Data vs. Cached Data


As I was reading the posts http://www.poi-factory.com/node/5107?page=3 about incorrect POIs, etc., I was sort of reminiscing about another hobby of mine and comparing and contrasting. I am a licensed amateur radio operator as well as scanner radio listener. My area has now gone to mainly digital, trunked radio systems, but back when things were analog, conventional hobbyists would often compare frequencies and sometimes even PL/DPLs. One of the inherent problems was old, outdated, unconfirmed data. Other technical problems could also crop up, like inter-modulation, harmonics, mixing, etc. Some hobbyists, in an attempt to reduce these problems, started posting whether a channel was actually confirmed. I was sort of thinking that it would be neat if we had the ability to do that with POIs, but it really isn't practical, yet, for most of us. If more of us had connected GPSs and/or smartphones and we visited the local pizzeria listed as a POI, we could touch a button to verify that the address, telephone number, etc. was correct and the data would get "back to the mother ship" so that others knew how recently the information was verified. On the other hand, maybe with the popularity of the Android Operating System and its Google Mobile Navigation, maybe POI confirmation really isn't so far away.

Along a similar line, with traffic information, timeliness is of great value. To know that there was a traffic tire up an hour ago is of little value if the tie up is now corrected.


Anyway, that leads me back to what I think is a classic question of our time right now. And that is, what is better data on the device (cached content) or data in the clouds (connected content)? We essentially deal with that now in entertainment in many areas. For example, do you watch satellite/cable/over the air TV or do you watch DVDs, etc. Do you listen to XM/Sirius, AM/FM radio, internet radio. Or do you prefer CDs, MP3, etc. Getting back to GPSs, do you prefer POIs stored on the device or do you prefer connected data from a smart phone GPS, Garmin Nuvi 1690 or (soon?) a Garmin Nuvi 1695?

For me, the obvious answer is BOTH, if it is possible. By that I mean if I am using my Garminfone and I am connected to wi-fi, since I don't currently have a data plan, I will check on board POIs and Google Local Search, if time permits. As an aside, since I have had emergency management training, I sometimes have a tendency to plan redundancy, even in my personal life, just in case. Or another way of putting it, even though I was never in the military, they have an old saying something along the lines of, "Two is one and one is none." Another hobby of mine is flashlights. So when people bring flashlights along, say touring a cave, they bring more than they need in case of failure. That is often a good thing to do with GPS. If you have a smart phone or connected GPS, you are all set, well that is until you CAN'T connect, then you will wish you had data stored on the device! (Getting off my soapbox now.)

Garbage in = garbage out

It doesn't matter whether it's data on the device or data in the clouds - they could both be inaccurate, and inaccurate data defeats the purpose of the device, whether it's a GPS or something else. Beyond accurate data is data which once was accurate, but it has changed. The only accurate data is in real time.

POI confirmation could help with all these situations. The question is - can it be made to work acceptably, and how much will it cost?

dobs108 idea

Agree with dobs108

First & foremost I agree with dobs108.. garbage is garbage regardless of timeliness.

Personally, except for traffic conditions and being too 'busy' (Im not) to update 'static' info on my GPSr, I don't see a need to be constantly connected. Certainly not at the present cost structures anyway.

Having said that, I really find the W-Fi on my 295W to be perfect for my needs. Static pois but with the ability to 'connect' to the WWDS (Web aka World Wide Data Source mrgreen ) when I need corrections, local data or conditions, and casual communications via email.

But then I'm old school and remember needing to carry change for pay phones while traveling, and how neat my Vic 20 was.

Oh yeah... I DO enjoy having my mp3's with me everywhere now, too.

About your verification thought.. I've been working on my GPX utilities Excel add-in the last few days, and was just thinking a similar thought but with regard to geocoding/reverse geocoding.

In the GPX file format there is field for each poi called 'Src" that is often never used, and often never exposed by software. I'm thinking that when a user uses my built-in geocoding functions, I'm going to indicate it in the poi by populating the Src field with something like "Google Geocode" or "Google Rvs Geocode". Perhaps we can at least start a 'trend' to put something like "(initials) Visited mm-dd-yy" in the field also?

It's about the Line- If a line can be drawn between the powers granted and the rights retained, it would seem to be the same thing, whether the latter be secured by declaring that they shall not be abridged, or that the former shall not be extended.
