Increasing Accuracy of Street Addresses and POIs

 

We have a pretty neat opportunity here with POI Factory by being able to create POI files and share them. I am just wondering what the future holds for the POIs on the GPS Devices themselves. What I am referring to is how street address and locations can vary somewhat. For example, a Walgreens near 15034 Shannon Parkway, Rosemount, MN 55068. Because of how POIs are created as a location on a road the actual location of the building may be quite a ways from a point on a road. Do you guys think that the future will have the actual location of POIs in the future. (Either Custom POIs or from the factory POIs.)

Also, I wonder if the future of address geocoding and reverse geocoding might include increased accuracy. I was thinking about this tonight when I went to pick up my son from a neighbors house. Because of the way numbers are assigned in that neighborhood, the location that Garmin software picks for the address entered is a couple of house away. Obviously, that is no big deal, but I was hoping that the future may hold a means to increase the accuracy of the geo-coding and reverse geo-coding. Maybe a way to enter certain points in a neighborhood that would allow a sort of "forward error correction" if you will. Maybe a type of "smart GPS geocoding" for example where you add certain known addresses on a street and the GPS interpolates (or would that be extrapolate?)other addresses on the street based on the updates.

I seems to me that memory continues to get cheaper, so devices with increased accuracy of geo-coding may require more memory, but hopefully at a minimal increase in cost. Maybe the place to start is with commercial POIs. The Walgreens that I refer to isn't located in the center of the street, of course, but is located some distance from the street.

I am very satisfied with how my GPS navigates now, I am just sort of speculating about what the future may hold.

The other thing that I think

The other thing that I think about from time to time is reducing the time between map updates. Granted, it takes some time for changes to get added to the mapping software, but I would love to see that time reduced. Even though "connected" GPSs seem slow to catch on with end users, I think the future will include the ability to share updates with others. That is what we are doing here on POI Factory. Take that another step further, and say a city adds a few new streets, it would be neat to have a way to add that street to the maps fairly soon after the street gets built.

Accuracy

Some inaccuracies will always exixt. While looking for real estate, I notice Google Strret View always plunks down up to 1/2 block off. I have to flip back and forth between the realtors picture and street view til I find the exact property.

With the technology now with geotaging the photos.It looks like that would be a big plus for people in real estate now.Just look at the picture with the coordinates on them.Plug them into the gps and go right to it.

If the house is between the the known addresses its interpolation. If it lies outside the known addresses its extrapolation.

Increasing Accuracy of Street Addresses and POIs

I think it depends on the type of POI as to how I would like to see them geocoded. But I can't speak for everyone else. It's obvious that something like a rest area or a time zone would be geocoded on the main highway, but when it comes to something like a zoo or other attraction, which may be a half or three quarters of a mile off the main highway I would just as soon have their parking lot geocoded. My reason for that is because POIs like zoos I don't just happen by them by chance, when I'm in a strange area I know what I want to see so I use the POI list the same as I do The built in POIs and when I find what I want I have the GPS route me there.

Anytime you have a 50-50 chance of getting something right, there's a 90% probability you'll get it wrong.

Accuracy

I think in the future maps will only get more accurate and be updated faster.

It would be great if the mapping companies had a way to compare satellite maps with what they show and be able to update streets that way.

Also I would like to see traffic monitored by satellite for the whole US, so you could get traffic warnings for side streets, and construction zone delays for rural areas.
