National map data center? |
|
|
Hi,
I have lived in my condo for over 25 years. The address is over 40 years old. Yet all
the maps I check have it in the wrong place. The only exception is Street Atlas which
finally updated the information I sent after about 6 years.
Is there a national map data center where I can update the data for my address?
Thanks,
mogur2 |

In the US, the US Census Tiger database holds some known points on various
streets. The addresses are then evenly divided between those points. In
some areas, this is absolutely correct, in other areas, I've seen it off by
five miles. The address data was originally purchased from a commercial
vendor, but it doesn't say who.
There is a method for the US Postal Service or local municipalities to
update the information.

Updating your own address could possibly be coordinated via the GIS
department of your county. It might be that the spacing of addresses on
your street is irregular, and there aren't enough incorrect addresses for
them to bother making the update.

It's nothing to do with a 'map data center' at all, it's just the software calculates
an estimated position along a road using a guesstimate of about 100 feet/house.
My house is indicated to be approximately 0.3 of a mile away from where it really is,
right in the middle of a main line railway !

I don't think so. You can report it to DeLorme. They are still using
data they create based on the Tiger database last I heard. Most of the
other companies are using Navteq's data which seems to be more current
and to have better more accurate locations in some areas or for some
objects. DeLorme brags in their advertising about having and
maintaining their own data but some people are finding Street Atlas
getting more and more outdated with every new product release.
If you look at Altons Avenue, Ellsworth, ME 04605, that has been mis
located about 1/4 mile to the north from it's actual location for years.
It shows that way on all the the USGS paper topos, on all of DeLorme's
maps, and was also off in the NavTeq maps until recently.
I suspect that the problem on Altons was that someone transposed some
digits or made a math error when drawing up some of the early mapping
products. They got the size and shape of the road perfect, it was
aligned with the road it came off of, but it was just in the wrong place.
MapSend's Topo 3D finally got Altons Avenue in the right place, also
added the 8 year old extension to it, and a couple of newer (only paved
for 2 years) roads at the top of it. They got the road names mixed up
at the top but the locations and contours are about right.

I know of a street that has 2 errors - it does not show the last 1/4 mile,
and seems to not show the correct path for the last 1/2 mile. I still can
find the 2 locations on the street I have visited, and one time just decided
to see where the street went to and found it was a faster way to my next
stop.
It is industrial, so probably not a huge problem.

Hi,
Sorry it took us so long to correct your information although it sounds
like everyone else still has it wrong. We have invested a lot in
enabling individual data revisions to be made, which requires both new
technology tools and lots and lots of mapmakers to hand-CAD all the
single changes. But...we really are making a huge investment/commitment
to further improving our overall U.S. street database, as well as
implementing a much higher percentage of all the user edits we receive.
The best place to submit corrections is at the link below, thanks.
p.s. I just saw C-Net reviewed both M-soft and us and preferred our
data while acknowledging that they were better in some places than we
were. Frankly, neither of us got a great review there, which surprises
me somewhat.
