Automation of corrections is quite rightly frowned apon. If there is any task in OSM that seems like there's not enough people to complete by hand, then the answer is to recruit more people.

I think TomH is being a little pessimistic on this, but certainly the few bots that we have need to be reigned in.

Yeah, I believe the problem is now people are fixing the duplicate nodes automatically. While some of them should be joined close to 100% of the time (edges of TIGER counties being one of them) others (such as NHD and TIGER nodes being coincident) obviously shouldn't.

Nakor, you should contact whoever is doing this and ask them to stop, if not take it to the mailing lists. There are sanctions available such as blocks to make people running bots pause and reconsider.

No, there's no test case system for rendering.

Watch out with what you do with the CGIAR dataset, since it can't be combined with OSM data. What you're doing with overlays is OK, but it's a dead-end path if you try doing anything more interesting.

Good work. Any more similar ideas up your sleeves?

Good work on the TIGER fixup - it's a long, hard and inglorious task!

I don't think that's correct - but you need to be careful on how the gap between dashes compares to the width of the line. So if you have a width of 2px, you'll need a gap between strokes of 5px to see a 1px gap. Each little dash gets rounded, and the round ends aren't counted as being part of the length of the stroke.

I'm not sure that having one page for "all videos" is a good idea - neither would having one page for "all pictures". However, there are tons of videos linked to from the various SOTM pages, e.g. osm.wiki/State_Of_The_Map_2008

Good work!

Don't be discouraged by the poor quality of the data - just get on and fix your area and encourage others to do the same! There's no magic pill to sort out all the routing problems, but there's no reason to not fix the problems at hand either. I spent an ungodly amount of time fixing interstates when I started the 250 cities project - hundreds and hundreds of hours. When other people saw the amount of work being done, they got stuck in too.

Make the area that you're interested in an exemplar of how to do things, and other people will raise things to that standard. But when everyone accepts the current state of play, then few people are motivated to improve things.

It might be the guys who are serving the imagery improving their rectification.

Hi Scocasso,

You might be interested in www.cyclestreets.co.uk - it's a site that combines maps and routing for bicycles and covers many of the ideas you have discussed. I think even in your discussion you show that there's too many different types of bicycle path to show every type differently on the map - it would be a confusing mess! Still, as Chillly suggested, you can experiment yourself to see what works or not.

Hi Scocasso,

Refreshing the legend on gravitystorm is on my personal todo list. If you would like to see the legend improved on the main www.openstreetmap.org web site, then please add a ticket to trac.openstreetmap.org and someone may get around to it.

As for why it hasn't been done in all the last two years, it's because I'm often busy with my day job, and there are usually more urgent tasks like trying to keep the cyclemap server running!

If you haven't done so already, you could join the Philippines mailing list ("talk-ph") and ask there too - it's nice keeping in touch with other mappers in the same part of the world.

Go for it, I've always believed that the park boundary is at position A, and the middle of the road is over there a few metres away. It's especially true in London where the parks have walls around them - things get a bit more fuzzy when the "park" hasn't got a physical edge to it.

I cleared a few doubled-up roads just north of there when I added the addressing up NW of Paddington, I'm not sure what the history is around there but looks like someone made a mistake a few years ago. They had Queensway appearing all over the place.

Have a look into http://trac.openstreetmap.org/browser/applications/utils/export/garmincyclemap/preprocess that might help

It's a problem with the coastlines shapefile, I'll have a look at making another one.

Good work David! A brave and hopefully successful decision for you and your company.

osm.wiki/Good_practice says "Don't remove tags that you don't understand". That applies equally well to the warnings from validators - just because they don't understand the tags, doesn't mean they are wrong!

Hi there, I use my digital camera and a Garmin eTrex for mapping - fits on my handlebars, does routing, and shows OSM on the screen. If you're looking for a recommendation of models to buy here is mine: http://www.gravitystorm.co.uk/shine/gps-recommendations

I don't have any recommendations for car sat navs though, I don't have any experience with them.
