Go into Potlatch ('Edit') for the area in question. Press 'U' for undelete. You'll see it reappear as a red line. Select it, then click the little padlock at the bottom to unlock, and deselect to upload it again.

Yeah - don't "save" them on the unit. Ever. It takes 90% of the detail out, not just the timestamps - the tracks are compressed so much that they're unusable for OSM. See the FAQ under "Why didn't my GPX file upload properly?" for more. :)

The reason we insist on timestamps is to filter out well-meaning but misguided people who take copyrighted data sources, convert them to GPX, and upload. Requiring timestamps means that they're more likely to be bona fide tracklogs (of course, the really determined could fake them, but you can never stop the really determined).

Sounds unlikely - I've never come across a Garmin unit that doesn't record timestamps (unless you "save" the tracks on the unit, which is a bad idea anyway). More likely the software you're using to download the tracks isn't storing the timestamps - what are you using?

Lovely area - will be great to see it on the map. I'm hoping to do a bit of mapping to the east of there (my mum's just moved to Church Stretton). Have you seen there's a mapping party in September a short way south-east, near Knighton/Kington/Radnor?

Yes please! I think central Bristol is the place I've got most spectacularly lost on the NCN, ironically within about 300m of the National Cycle Network HQ - once you're past the cathedral (heading north/west), the signs for NCN4 and NCN41 just seem to disappear. We caught up with NCN41 again somewhere around Avonmouth...

Eeek, here be ultra-keen building mappers. You people with Yahoo imagery are spoilt, you really are.

I think we need a word for 'roads/paths that run between two places roughly equidistant from your house, so you never drive/walk them because you go directly to one place or the other' - this was probably one of them.

Agree with Rob - gpsbabel+ makes it easy.

(Incidentally, you might have noticed a few little streets appearing here and there as part of the on-going project to get some Swindon primary schools adding their local areas to OSM - feel free to capitalise the street names when they're all in lower case, etc. :) )

Great stuff!

We cycled route 45 north from the station (ultimately to Gloucester) earlier this year - but as you've probably noticed, there's actually a "braid" in Swindon (i.e. route 45 splits in two), so there's quite a lot to map...

It's a bug, I'm afraid - http://trac.openstreetmap.org/ticket/967 . Haven't had chance to work out why it's not working yet.

See osm.wiki/index.php/OSM_Map_On_Garmin , and in particular, mkgmap.

Don't have any experience with Firefox 3, sorry. On Firefox 2 it works ok for me; on Safari I select View->View Source.

You'll probably need to "view source" or similar in your browser.

Also see the splash screen that pops up when you first open Potlatch:

"If you click 'Start', you'll be editing the main map directly"

i.e. no need to explicitly save; and

"changes usually show up every Thursday."

Incidentally, Potlatch is plenty open - the source is at http://trac.openstreetmap.org/browser/applications/editors/potlatch/ and the Gnash guys have done a lot of work towards making the two work happily together.

TvdB - you are welcome to volunteer as a developer if you think you can do it better!

Roger - that's one of the best expressions of the "OSM philosophy" that I've ever seen.

highway=trunk: A road, green signs

highway=primary: A road, black and white signs

highway=secondary: B road

highway=tertiary: no road number, but a significant road for getting from place to place, usually with white lines

highway=unclassified: any other minor road except...

highway=residential: small residential road in town or village, used primarily by residents

Suggest you buy an eTrex Legend HCx then give a tenner to Osmf to salve your conscience!

You can never, ever copy anything, at all from Google Maps - or any other map, unless it's a very old one (typically at least 70 years) and out-of-copyright. If you've forgotten the name of the streets, take better notes!

Fixed as of 0.9b. (0.9b isn't committed yet, though, because trac's down.)
