Last night I added my local mini-roundabout to OSM by zooming in close and drawing a small circular road. Cleaned up the data using the button that looks like a row of dots and I have a nice small circular roundabout.
Did I do wrong? Should I have simply selected the point were all the roads meet and tagged it as a mini-roundabout?
I am new to OSM and trying to update my local area but I don't want to make their data worse in my attempts to improve it! |
that would imply a real roundabout where the road physically goes in a circle. a mini-roundabout, as far as i am concerned, is a straight road with a lump of white paint in the middle.

Thanks, the roundabout in question is a junction with a blob of white paint in the middle. I will correct my correction  _________________ Paul |

cheers for the tip on the 'make a nice circle' button too - i used that today when adding a real roundabout near me on my travels! thought i'd make the most of PGPSW site being down this morning so logged and added about 10-12 miles of roads in the next village :D

Worth remembering that TomTom make the owner pay for their mapshare thing when you actually do the work yourself and fill it in for them!!!
Reminds me of that old BlackAdder episode were they are off to the Cape of Good Hope, Melchett gives them a map of the area and says:
"The foremost cartographers of the land have prepared this for you. It's a map of the area that you'll be traversing."
(The map is completely blank.)
"They'd be very grateful if you could just fill it in as you go along."
Melchett must have been a founder of Teleatlas!! |

just found this re: maxspeed: http://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Maxspeed
basically, it seems like they have default speeds set for the road type so not all teh speeds need adding, only those that differ from the norm. however, it sort of implies that the speed needs putting in in kph which could cause confusion and potentially the stupid rounding errors as seen in TomTom mapshare speed edits!
further reading and i find this: http://wiki.openstreetmap.org/wiki/Key:maxspeed
which states you need to specify mph eg: '30 mph'
BUT says that default speeds aren;t doen automatically, you need to put the speed as 'DE:motorway' i.e. the default motorway speed for that country...
perhaps we should split this thread or all join the OSM forums to discuss!

Brilliant! I have messed up again. I have been tagging all the roads that I have added in town as maxspeed 30. The problem is that I now don't know what I should be tagging them as. DE:urban? maxspeed 30 mph?
The maps are wonderfully versatile with a tag for everything you can think of. If the tag doesn't exist then you can create a new one. The problem is that as a beginner l would much prefer a simple set of tags that I should add e.g. Road type, name, maxspeed with clearly defined rules for the values allowed for the tags. In that way I will be helping the project rather than degrading it.
Is there a way to select all the roads in an area and change a tag for the whole lot in one go?
Edit: Following our earlier discussion on mini roundabouts I have discovered that just tagging a point as a mini roundabout is not adequate in the UK. Quote: | Use direction=clockwise to identify clockwise mini-roundabouts. Anticlockwise is the default rendering when not specified |

re speed limits - been chatting to others via the wiki pages and the 'DE' was an idea being bandied around for german users to set different road speeds per vehicle... simply leave it blank and the default speed will be used, only add the speed when it is not a 'standard' speed, eg a 50mph stretch on a motorway, or a 20mph local road. MAKE SURE you put mph! ie: '30 mph'
didn;t think you could change teh rotation of a mini-roundabout? the rotational direction only seems to appear for an actual physical round bit of road...?!

Quote: | Rendered as anti-clockwise by default. To render clockwise add the tag "direction=clockwise." |

Using Potlatch you can click the + to Add a new tag and then type in "direction" as the tag and "clockwise" as the value of it.
I still can't find any way to select a whole bunch of roads to correct my 30 mph error  _________________ Paul |

What's a GPS logger or software capable of logging? |
The 2010.10 maps have greatly improved Greece coverage but they still lack a lot of names and POIS. So far the best Garmin map for greece is provided by a company www.autodrivehellas.gr
you can view the website in english version as well.
I hope this helps |

I have been out walking the streets with my GPS in the Weybourne and Hale districts of Farnham so the coverage is much better now. Not been arrested yet Good way to keep fit too  _________________ Various TomToms, Garmin eTrex Legend, GPSMAP 60CSx, Oregon 550t, Forerunner 405 |

Just an aside. - I've been adding a few more roads on OSM in and around Figueres, Spain, and I have just noticed a natty little button entitiled "Where Am I?". Evidentlty I am on the Polish/Russian border in a place called Terespol. Presumably this works on my IP address. No wonder BBC iPlayer doesn't allow me to watch EastEnders
