Hello

A few local users started adding roads on the map of Iasi, Romania
( http://www.google.com/mapmaker?ll=47.158439,27.60006&spn=0.087427,0.232086&z=13
). A couple a days ago, the satellite image changed with a better one,
so the roads coordinates were changed (I think that the old map wasn't
accurate).
Do we have to redraw all the roads, buildings and points of interest
to match the new map, or can any administrator offset the vector layer
to the correct location ?

Thank you

Hi

It would be ideal if the GMM administration group suspends, adding of any data in the imagery after its updation, for a fortnight, by which time all the vector data could be ported to the new imagery. This will help other map makers from deleting the existing data (which are almost inaccurate) and add new data. Even the imagery now added are also up-to-date compared to similar imagery available in Google Earth. If the user edits the data in the current imagery, he will also be required to do the same process of deletion and addition in future when the imagery is updated (necessarily).

Thanks

Hi,
Yes CNR Nair, we advise everyone not to delete the existing data
even though it is misaligned. We are automating the alignment process
and all the features that had been added earlier will be automatically
aligned with the newer imagery. This process is taking a bit longer
than expected and we are working hard for getting it resolved soon. If
you find areas that have misaligned vector data, please post such
areas on the Issue Tracker ( http://code.google.com/p/google-mapmaker/
).

You may however continue to add new data based on the new imagery.

Regards,
Map Maker Guide.

Map Maker,

Am I hearing you correctly that if we add features based on the new
imagery that the old features (which are misalinged) will be aligned
and the new features will remain in place. In other words, if you
have to shift all of the old features to the left by 10 meters the new
features will not move with them.

Is that true? I have been holding off adding new features as I figured
they would move when the misaligned features around them are
corrected.

Let me know. Thanks.

I suggest make new Roads but do not connect them with old Roads. Leave
space in-between to be connected when the old Roads have been aligned
on the new Imagery.

Gorio,
you are hearing this right. The new features you draw will remain
aligned and the old features will get aligned to the new imagery. Like
you heard, we are working on creating better tools to auto align to
new imagery which are not rock solid yet. But no algorithm is ever
perfect, so even going forward, you will always find small areas that
get misaligned, just report them as suggested and we will help out,
usually very quickly.

I expect the areas reported so far to be aligned and cleaned up in the
next two working days.

thanks,
mapmaker guy

Hi NHK,

Please don't think that I'm picking up on something but it is not really a good idea. Since newly added features will not be disturbed by realignment then it is better for roads to be connected. Many thanks.

Old Roads are presently misaligned at most places on the New Imagery
and there is no Road below. If new Roads are linked up with them on
the New Imagery, a portion of the New Road will have no Road below it.

Subsequently, a whole new process will need to be initiated by
deleting that portion of Road and then creating a Road and connecting
it.

So why not do just one action when the New Imagery is aligned - and
connecting it with correctly aligned Old Road.

We will have to live with this issue for next 2-3 years, in my
opinion, since over 50% of the Tiles still have poor imagery and
consequently not very accurate roads - which will need to be corrected
as the bad Imagery gets replaced gradually.

This is not only an issue with roads, but also with rivers and railway lines.
I have tried to correct some railway lines and roads and while doing part of it, message appears that it requires moderation. Therefore it would be better if the GMM Team corrects the imagery in a definite time frame or allow users to modify it.

Deleting is not a necessary every time in this process of alignment. I have aligned a huge part of M-8 and N-55 in last few weeks by just moving the intersections and road to its correct position.

It would be suitable if the roads/rivers run on straight line, but if the roads have a lot of bends and turnings, it would be better to delete and redraw.

Hi
How to move an intersection from one location to another.
There is no option to move it as in the case of a POI.

If you draw an extra Road, which is has no Road below it but is
required to link with a misaligned Old Road, you will have to
subsequently Delete it. This is the New Road that has connected a
misaligned Old Road. There is no other way of getting rid of this
extra portion of the New Road. I have experienced it.

You could Move the Old Road instead of Deleting & re-drawing but I
prefer Deleting.

Nair

I think the GMM has intentionally put this `Moderation' for prevention
of deleting the Old Roads which are misaligned - as they are already
in the process of aligning them. And they do not want the whole lot of
Old Roads to go through this Deletion when they are doing the simple
thing of aligning them.

just my guess.

Hi,

  Actually there is :-). I was hunting for a long time for this...

1. Choose the intersection - and chose "Edit this intersection and use the hand icon to move it to the correct (new) place.
2. After this, in the left-hand pane you get the option of Add Details. Click here and you see the "Save" option.

Regards.

Intersections can be moved by choosing their edit option and so POI as well. Cheers

Yes. My explanation was bad. Here it goes:

A- An Old Road is misaligned, is not over the actual road and is at a
distance. (North or East or West or South)

B- We are trying to make a New Road & trying to link it with the
misaligned Old Road.

C- If we end up linking with the Old Road, there will be
``Distance'' Our New Road will either be short of the actual road or
will cross the actual road to be link.


Example:
http://www.google.com/mapmaker?hl=en&ll=30.925329,69.128079&spn=0.009921,0.021801&z=16&t=h

If NH50 was to be linked from the East, it will have to cross the
actual road to be linked.

regards

I would say you carry on as you like. Since we are already aligning the highways so it may eliminate any concern.

Map Maker,

Can you weigh in on this? Since you should know the system, what is
the best thing to do when you want to connect a new (aligned) road
with a misaligned one? Should we not do it? Or how will the system
correct a connection made to a misaligned road?

I still have many misalignments in my usual mapping area. This
information would be useful now and in the future.

Thanks.

Hi Gorio,
Thanks for sharing your concerns. Adding new features based on the
new imagery now will not lead to them being misaligned. I say this
because the automatic alignment that I had mentioned earlier has not
performed as we had hoped it would. Let me elaborate a bit on the
steps that are now being taken. This process might take a bit longer
than we would like and we apologize for any inconvenience. Our team
will now be manually aligning the areas as follows:

- Roads will be aligned first.
- Polygons will be aligned next.
- We will try our best to align the features marked as points. But, as
we might not be able to judge the exact position, we would need your
help with those.

So, new features that are added now in accordance with the new
satellite imagery will be left untouched. In the specific case of
roads, you can add the new roads as per the satellite imagery and
connect (& extend if required) it to the misaligned roads and while we
are re-aligning the roads, we will not touch any of the roads that are
already aligned.

NHK has given an excellent example for this :
http://www.google.com/mapmaker?hl=en&fll=30.92866,69.125934&fr=0.000736,0.000858&mpp=2.048976&gw=39&ll=30.927979,69.125333&spn=0.013842,0.020428&t=h&z=16&iwloc=0_0&fid=4120396784466591413:3500251784740782445

In his case, he just drew the one section while extending the road and
left the misaligned sections, which will be realigned subsequently by
us.

Hope that clarifies your doubt. Please let me know if you have any
concerns.

Thanks & Regards,
Map Maker Guide.

Hi,
It is not clear to me where in the Issue Tracker I should report
misaligned areas. None of the issues are related to misalignment
except one with two votes regarding the Dominican Republic.
There is a lot of misalignments in Central Serbia.

Hi Drago,
If you could not find an existing issue reported for your area, you
can create a new issue on the issue tracker to report the location of
your interest as described more elaborately here: http://code.google.com/p/google-mapmaker/
using the template 'Misalignment Issue'.

Hope that helps.
