Interesting GPS trace, and other MapDust oddities
25 ফেব্রুয়ারি 2011 তারিখে English ভাষায় chriscf কর্তৃক প্রকাশনাThis is an interesting trace. Not least because it would involve walking or cycling directly through solid ground, and then through two walls.
Of course, MapDust has reports that are useless in other ways, such as this. Someone has failed to appreciate that without knowing the intended route, I have no idea whatsoever why this person was instructed to exit the motorway, or why they felt it was inappropriate.
That said, reports such as this should just be rejected automagically.

When I see bug reports like this, I check a few streets in the area to see if there's unconnected roads, or likely turn restrictions.
It's probably an accuracy error with his iphone.
ps. looks like there's some footpaths west of the second 'this' link.

Perhaps the first trace was someone using a smart phone in a light aircraft.

I would disagree with automagically rejecting reports - while a single report like that is mostly useless, a few of them in the same area is a strong hint to a local mapper that 'something is wrong', and that the area would be worth resurveying/checking.

I've too once fallen for the impression that I could fix those mapdust problems with 'armchair mapping'. Well you can't.
In my surroundings I see a lot of speedtag-issues without the right speed entered, missing house-numbers without the actual number, missing house-number with the number, but placed right in the middle of the street (which damn house does he mean?) or missing turn restrictions without a further hint on from where to where.
You still have to go out there and have a look. You may now what to look for with the help of the mapdust error type and comment, but you just can't fix them without verifying them on the ground.
While it still is useful, it's mostly not more than a 'take a closer look in this area' indicator.

To be fair to the Skobbler user, the report would have made perfect sense in their context. It is the application that needs to be much clearer on the kind of detail required (or have an optional feature to upload the entire route for this purpose).
Regarding rejecting reports, Andy Allan reports (on talk-gb) that there is now a "default description" flag that can optionally be used to suppress such bugs (and P2 soon will):

@Chaos99 - it is true that most bugs would need to be checked out on the ground, but there are occasional exceptions - as alexz says, it can be worth looking at the ways around the bug for any obvious errors (such as broken junctions) that may have caused the poor routing.

The most useless have to be "Nothing to Report" - e.g. http://www.mapdust.com/detail/134495 - or those posted in a foreign language with no indication of what that language is (Google Language Tools can't even work it out on the few occasions I have tried)

The one I pegged as completely useless was an "Other" category report, with no supporting comment, without a proposed or actual route. I would think it would probably be better if these never got through in the first place. There may also be issues with Skobbler's rendering, since I've closed two reports claiming missing miniroundabouts which were on the map for at least a year before the report was filed.

If you check keepright.ipax.at , there's a couple unconnected roads in the area.

Not sayin that that's their issue, but when you combine the accuracy of an iphone with unjoined roads.. you may have interesting routes.

They're false-positives. One of them referred to an admin boundary that isn't and shouldn't be joined, and the other appears to refer to a land-use polygon. Could have been someone saying "my house number is wrong". Alternatively, it could have been someone mis-clicking on the MapDust map.

I hate it when people post bug reports that make no sense! It really degrades the usefulness of MapDust. Mapdust would be way more useful if people actually took time to explain in depth what the problem is.
