The forum is here: http://forum.openstreetmap.org/ It does have a section for users:Greece, though I’m not sure how active it is.

Or details of mailing lists here: osm.wiki/Mailing_lists It looks like there isn’t one specifically for Greece. You could try the general “Tagging” list.

A few more links I find useful:

http://open.mapquest.com/ - does car, bike, pedestrian routing

http://www.cyclestreets.net/ - very nice for planning bike routes (UK only)

http://garmin.openstreetmap.nl/ - if you have a Garmin GPS device, this is probably the easiest website for adding OSM maps.

For using Potlatch 2 on openstreetmap.org, press M to hide the left panel.

Send a polite message to that user, asking what they are doing, and what sources they are using. And explain that OSM is a map of the real world, and that they shouldn’t be adding things which don’t exist.

Though it looks like they haven’t edited in over a year, so you might not get any reply.

You could ask on the Talk-US mailing list, to see if there’s anyone familiar with the area.

Or you could set up Mapnik to work in the OSGB projection. There’s instructions here, but it look a bit complicated: osm.wiki/Mapnik_GB_Projection

Then you could use Mapnik to generate SVG images.

If there’s particular tags that you are using frequently, you can add them as buttons on the toolbar. Then its quicker and less clicks to add them.

Go to edit menu > Preferences, then choose the icon for Toolbar (5th one down). Then you can select presets from the menu, and add them to the toolbar.

If you want to use tags that are not in the standard presets, then you can create a custom presets file. See http://josm.openstreetmap.de/wiki/TaggingPresets

Plug in the Etrex with the USB cable, then go to Main menu > Setup > Interface, and select the option for USB mass storage. Then the memory card will appear as a drive on your PC, so you can copy the GPX files off.

I’m not sure if their is any server limit for uploading GPX tracks. If there is, it is pretty high. It might be quicker if you zip the GPX files before uploading.

It would make more sense to tag it as golf=buunker plus surface=sand or landcover=sand.

It probably is due to the licence change. OpenStreetMap has now changed the licence from CC-BY-SA to ODbL. So it was necessary to ask all contributors whether they agreed, and remove their edits if they didn’t agree.

See http://www.osmfoundation.org/wiki/License/We_Are_Changing_The_License

and http://blog.osmfoundation.org/2012/07/26/automated-redactions-complete/

In much of the world, this didn’t affect the map much, as most people agreed to the licence change, or things from non-agreeing contributors were replaced before the change. But some areas were affected more, including parts of Australia.

If the map is now incomplete or incorrect, please do help to fix it. ie by surveying or using local knowledge or aerial photos to edit the map.

Map the amenity as an area, ie the building outline (assuming it fills the whole building). So an area tagged amenity=bank and building=yes. If it has a range of housenumbers, you could tag that, eg addr:housenumber=5,7,9 etc.

Then add nodes for the entrances onto the outline of the area. No need for a relation, it is obvious they are connected. If the entrances have their own housenumbers, you can tag them with that.

I think it would be more useful to encourage people to use meaningful changeset comments/tags. ie specify what source you use for the edits in each changeset.

As this example shows, source tags on objects are often not helpful. As people edit the objects, but don’t update the source tags.

The postbox details on that Dracos website are from a Royal Mail list, which is possibly copyright. Plus both the refs and collection times can be inaccurate/out of date. So probably best not to copy anything from there, instead survey what it actually says on the box.

Also, if you’ve not seen it already, this website is useful: http://robert.mathmos.net/osm/postboxes/ It highlights possible problems with mapping and tagging of postboxes in OSM, so you can check them and fix them.

What you are looking for is an “isochrone map”. See http://en.wikipedia.org/wiki/Isochrone_map

Also osm.wiki/Isochrone That page has a links to some OSM based examples.

See the OSM Inspector Redaction view: http://tools.geofabrik.de/osmi/?view=redactionbot

It highlights where things have been changed or deleted by the bot. Though as Zartbitter says, you should not copy from there. Instead remap it from other sources.

In that example the nodes have been redacted. Presumably the track was traced by someone else previously, then Wbski split the way for some reason. So it was a ‘new’ way, but mostly using ‘old’ nodes.

It sounds like someone else had edited those ways, but they had not agreed to the licence change. So their edits are redacted.

And Potlatch will not show the redacted versions in the history.

You are changing road names previously added by others, which were probably from a survey and/or local knowledge. What you makes you sure those other mappers are wrong?

And by doing this it makes it harder to find actual surveying errors, as the area will now show as ‘correct’ on tools comparing it to the OS data.

If you want a ‘complete’ road map you can use the OS OpenData already. There is no need to to dump it all into OSM.

Have you surveyed any of these roads, to see if the names are actually correct?

What is your real name? What is your real OSM account? What company are you working for?
