Keeping an eye on the map

This is a request to all mappers to keep an eye on the areas that they are familiar with on the public map - http://www.openstreetmap.org. If things are not as they were, it should be due to improvements, not losses of data.

Examples - in the past year or so the Hyderabad city node has vanished twice, and has had to be replaced. I've just noticed that Vadodara too had vanished from the public map, and found that while the node was still there, complete with most tags, that the 'place=city' had been missing for some months, thus making it invisible. These appear to be all due to errors, not vandalism, but of course at any scale it makes OSM look unprofessional. Especially so when they are large cities like these two, but at any scale there should be certain key sites visible.

Re: Keeping an eye on the map

I feel someone has been deleting the 'woodland'/'forest' tags. Especially around Junnar/Bhandardara etc. Most of this region is forested. Of course there is a lot of farmland as well, but most of this region is forested.

You can see from the half rendered tiles at various soon levels. maybe I am mistaken. Can someone tell?

Re: Keeping an eye on the map

You could try Owl - http://owl.apis.dev.openstreetmap.org/ but I've not got anything out of it yet.

There were unusual numbers of editors working on India last week according to OSM stats, but they did not add many nodes.

Re: Keeping an eye on the map

Now the city of Chennai has vanished! This seems to have been some time ago by the look of things, because it cannot be seen at any resolution. I can't find it, and because I'm not sure where the original was exactly it is difficult to find the area history and figure out how it happened.  The history of a congested city centre is complicated.

I've replaced it with a basic place=city/ name =Chennai node. But ideally we would find the original and revert its undeletion / change, since it will have a load of other useful information on it (names in other scripts, population, et.c.). If anyone knows how to retrieve it, that would be useful.

Re: Keeping an eye on the map

I've located the deletion and replaced the node and the tags (though not all the relation links for the city node). A new user seems to have been experimenting. It would be useful if anyone with knowledge of Chennai near the beach looked at his/her work, some of it looks dubious.

Re: Keeping an eye on the map

No, the town is  still there (Chikkamagaluru, the standard Kannada name), I can't see a deletion or anything in its history.

http://www.openstreetmap.org/history#ma … 81/75.7776

The forest polygon that overlays this area needs to be adjusted, the place is actually surrounded mostly by farmland as one would expect.

I've adjusted the name:alt value to 'Chikmagalur'.

Re: Keeping an eye on the map

Just unclassified a bunch of local roads in Chikkamagaluru that were tagged tertiary. Also any clue if this is actually a reservoir, looks like it used to be an airstrip? http://www.openstreetmap.org/note/10778 … 0&layers=N

Re: Keeping an eye on the map

In response to PlaneMad's query of 21st August

'Also any clue if this is actually a reservoir, looks like it used to be an airstrip? http://www.openstreetmap.org/note/10778 … 0&layers=N'

See this NEWS9 broadcast video on Youtube  https://www.youtube.com/watch?v=yhnf6XJMH7A . The geographic coordinates of the airstrip can be seen on a signpost in the video. I've therefore marked it as such and changed the area tag for the surround area from wetland to grass, though the land might possibly also flood at times from what seems to be a stream that can be seen on the south side.

Re: Keeping an eye on the map

Hi,

is there somebody they can take care about this guy:
http://www.openstreetmap.org/user/Rajes … 47/81.9598
around 850 changesets of invented data. He invents airport/railway stations/ big roads/shops and so on.
I dont speak Hindi maybe somebody from India can take care and tell him that he destroy the Indian Navigation Maps. I wrote him many times in English without any result.

Best regards

Thanks for doing that, but can I possibly suggesting using changeset discussion comments rather than OSM messages to do that?  They're public rather than private, which means that other people will know that there's a problem and can act accordingly.

(my apologies if you have been using changeset discussion comments to communicate - I had a look back through the last 14 days and didn't notice one)

Re: Keeping an eye on the map

I deleted a lot of wrong things. But nothing in the last 14 days.
I wrote on 2. November to this adress:
data@osmfoundation.org
Without any answer. Was this the wrong adress?

We were aware of the user already (they were blocked previously in https://www.openstreetmap.org/user_blocks/961 ).  Looking at that day I see 17 DWG-related emails one of which (after cross-referencing changeset discussion comments with the forum name here) I presume was from you.  It looks like it was acted upon (some other investigation was done), but it looks like there was a misunderstanding about who was going to perform the next action, and one of the things that didn't happen was an acknowledgement to you that your mail had been received.

Do I read "I deleted a lot of wrong things. But nothing in the last 14 days." to mean that "there has been no problem data added by this user in the last 14 days" or "they have continued to create problems, but I have given up fixing them for the last 14 days"?  If the latter, are any changesets pending revert?  What I don't want to do is to block them again if 14 days ago they started making sensible (even if not very high quality) edits to the map and stopped making fantasy ones.

One of the things mentioned so far was that they may not have a good command of English, so it would be helpful if users of this forum could regularly monitor http://resultmaps.neis-one.org/osm-discussions?c=India and if they see a changeset discussion comment in a language that a local mapper may not understand to add a translation.  I'm guessing here that that would mean Urdu?

Re: Keeping an eye on the map

Hi,

I wrote three mails in past regarding this user. The other 14 are from different users. 14 days ago I tried to inform the DWG group but nothing happend. The main problem is, that he invent a lot of data thats never exist. e.g this airport : http://www.openstreetmap.org/#map=15/26.7955/82.1593
Furthermore he creates railroad station that not exists and so on. Also a lot of roads are complete / partly wrong. In this area we was mapping the correct ref numbers but he change them on his own way and invent new numbers. He mappes bridges that not exist, and so on... . I reverted that shit in the past regulary, but now he change everything in small steps. It is a lot of work to revert this shit and I have not the time to do this. Please revert everything and block this user!

Furthermore he has some other accounts. I will inform you if he activates one of them.

Best regards

Re: Keeping an eye on the map

To clarify - the DWG does not have a "magic wand" to wave.  If someone's been adding dubious data over a period of time, and other mappers have been active in the same area, we'd need to go through exactly the same process of untangling good edits from bad edits as anyone else would.  I can understand that you "have not the time to do this", but don't forget that DWG members are all volunteers too!  What really helps us is actionable information - a report of a fake airport with a link to the changeset is actionable; saying "a lot of roads are complete / partly wrong" and "he maps bridges that do not exist" is not without more detail.  I notice that you've been tidying up there recently (http://www.openstreetmap.org/way/454068761/history - for which thank you) but the mix of edits effectively means that a simple revert isn't really an option.

Re: Keeping an eye on the map

Yeah, yet another reason why the only sensible thing a normal mapper can do in such areas, where known mass vandals are left running lose, is to quit mapping altogether. And most that are driven away will probably never return, seeing that their hard work is considered worth nothing compared to the "contributions" of vandals doing mass destruction or otherwise rendering the map useless with fantasy edits. Just because in the wildest dreams possibly 1% of vandal edits may some day be anything useful. So of course those few (if any) additions FAR outweigh all the additions by normal mappers which were destroyed or damaged before:
Thousand good contributions destroyed, map useless now? Doesn't matter. Let them continue destroying. Click-click, poof - messed. Fun! Click-click, poof - another. That's fine, they are welcome, proven by no one stopping them, so they happily continue.
In return they may give back two or three 'good' contributions some far day, possibly? Worth GOLD! Diamonds! THOSE edits are worth it to destroy countless hard work hours of normal mappers. Not only in the past, but also the future, because sooner or later most people will get the message that their work is worth absolutely nothing compared to the 'work' of vandals and will give up. Time is too precious to waste it for nothing.

Re: Keeping an eye on the map

@wycbtma , the DWG (and all the other people who try and ensure that OSM is the domain of mappers trying to represent the real world, not people just wanting to draw doodles or add spam) welcome all the help that they can get to try and identify and resolve problems.  As I said previously, actionable information such as "this airport is fake" is useful.  I fail to see how your post above is.  If you'd like to help please do; but sitting on the sidelines and complaining won't achieve anything.
