Saipan data is in a sad state over 2 years ago

Latitude and longitude can vary depending on what geodetical system is used. There was a problem with the original TIGER import that, although the mainland coordinates used WGS84 which we use, some islands did not.

We have also had problems with imagery being offset so if there any GPS traces for Saipan you should check what you are doing against them.

TIGER data is also of variable quality so it could simply be wrong.

Keepright trends in my area over 2 years ago

The orphaned nodes were left in after redaction to help people regenerate the map by linking them with new ways but they probably aren’t as useful several months on. Talk about it first on your local mailing list (talk-us) if you want to get rid of them.

If you do delete unused nodes take care not to trip up anyone in the course of mapping by deleting newly created nodes.

East Rock Park over 2 years ago

Welcome to OSM. One thing to watch is that although Bing is better than the streets imported from TIGER that haven’t been tidied up in much of the US, the images are sometimes offset and I like to have GPS tracks displayed in the editor so I can check how accurate they are.

Cheshire Cheese pub meet-up a while back over 3 years ago

I use the OSM database of stored GPS tracks to calibrate Bing imagery. At the moment zoom level 19 is accurate and 21 is offset; a few months ago it was the other way round.

Another thing: are you recruiting any local mappers?

Are you sure the village names are not just older mapping that has slipped through the net?

More Bing! coverage over 3 years ago

Do you think the people complaining to Foursquare about poor OSM coverage of Brazil have a point? Can we as a community keep them happy?

How about mapping all buildings in London before the Olympics? over 3 years ago

Thank you for pointing out that the lower levels are more up to date. I have got into the habit of using zoom level 21 in London because of the better alignment.

Ways and relations over 3 years ago

First of all you would probably be better off asking this question on the OSM Help Centre or a Japan-related Contact channel.

Whether or not it is better to use route relations for road numbers is a question of local conditions such as whether roads are signed with two numbers equally.

There is generally no need to repeat the numbers of roads in their names.

Tom: I was thinking of doing just that as soon as ODBL compliance issues have been sorted out.

Introducing Team Surrey over 3 years ago

I have been treating the work of the main non-accepting mapper in the area as possible trap mapping and making a clean map. For instance I got no response when I asked why he had given a road a number I could not find on other sources and some cycle routes he put on the map appear to have been invented by a club he belongs to.

To make this clear, this post is about landuse polygons that extend beyond the edge of the land they represent to the middle of the road (or the middle of the carriageway), where the road has been mapped as a single line.

You might as well let the Vale of Glamorgan journey planner know.

List of Additions that I made to the Bermuda Map about 4 years ago

Most of the existing map of Bermuda has been added by outsiders tracing aerial photographs. Finishing it off takes locals like you. Don’t forget you can ask the rest of us for help.

Heads up TriMet about 4 years ago

Is there ever any point in putting the road number in the name= field? We always leave name= blank on motorways that haven’t got proper names in Britain.

local OSM meetups - that's it over 4 years ago

don’t know about anywhere else but there are quite often meetings scattered round the UK as well as the regular events in London and Birmingham, and they don’t show up on the map.

Practice make perfect. You’ll find things easier as you put more stuff in.
