Where abouts are you?
There's places(cities, towns, countys) where I'd trust OSM to be more accurate than Google Maps even if I haven't been there. Your probably just in a place which nobody has been near to map, often if you start the ball rolling others will want to add stuff too (or tell them about it and even get a mapping party/weekend set up to let people come and help you!).

I know the feeling. Try doing a 6 hour cycle with it recording fine, till the application crashes and losses it's data. I imagine your hills were bigger than the ones in Croydon though.

If you want a cheap GPS you can get a bluetooth one off ebay for about £15. It won't do anything useful on it's own, but if you install a program on your mobile phone, like GPSMid(free), then that can connect over bluetooth to receive the GPS data.

Layers are not supposed to be used like that. Layers are when a road actually goes over/under another road/path/railway.

It's worth learning the multipolygon way to make islands.

Are you waiting for someone else to map the streets?

If you've done the mapping and uploaded it then the update should happen on Wednesday morning.

Yep, stay away from just using name=something because that appears ugly on the map!
At a London no-name mapping marathons we decided if you add a lot of detail (building outlines/names, telephones, postboxes) around the roads you've checked then it looks more like someone has been there. Generally there will only be one or two isolated no-named roads in real life so that can be accepted, unlike a big clump of unnamed roads which were probably traced from aerial photography.

In the mean time you could just drop "note=there really is no name" in for anyone looking at the data before going out.

To highlight multiple items in JOSM do it like this:
click/select the way/street, hold down shift and select the node/point, then both are highlighted.

I don't know about Potlatch (the online editor), but that might also be by holding down shift.

Brilliant, there seems to be a lot of new activity springing up around Derby.

It looks good. I live next door in Hampton and just saw you put the boundary in.

Perhaps it's worth subscribing to http://www.planningalerts.com in the way Ordnance Survey monitor new planning applications.

Why do you have two?

I too use GPSMid (used to use TrekBuddy).
You easily buy a bluetooth GPS receiver for under £20 on E-bay. They seem to be 54 channel now (hears more satellites), where as I got a 32 channel one a couple of years ago.

Did it work?

It's probably been done with a GPS and, as njd27 says, the aerial photography out.
Also not everyone uploads their GPS tracks, some people just open them locally in JOSM.

Some of those roads (Via Alffianello, Via Capizzone, Via Brembilla, etc.) aren't connected to Via Carlo Albizzati. If they are in real life you need to make sure they are connected in the OSM editor (Potlatch or JOSM) so routing programs will send cars down them.

See the junctions section on this page:
osm.wiki/index.php/Editing_Standards_and_Conventions#Junctions

If there is a wall at the end of the road of something actually stopping cars then you are right, they shouldn't be connected.

Think of it as a perfect world that the council get the demand just right and everyone parks neatly. I would say those loops are designed for two bikes (though a family could chain 5 bikes together on just one side).

Actually I haven't been bothering with tagging capacity yet, and isn't it a bit pointless without knowing the demand at certain times of the day.

Looks like there are a handful of unnamed roads to be done.
Good luck with GPStogo.

Cows put me off too. Never met them in the dark though, I think I avoid fields then.

Make sure you check any cases in real life.
I have frequently found roads that stop just before another road, with a thin brick wall separating them. Sadly on the renderer this can look like they connect.

It looks like a road over the river had been stub-mapped. And was the landuse=construction area already there?
If so maybe someone knew something was going on and the above are sort of notes to revisit the area, if they look at that part of the map again. In can be easy to forget parts of where we live and what's going on there.

Anyway, a vision of OSM is that individual new roads can be added as soon as someone noticed them. Perhaps one day we will be watching the planning applications office like the OS do. Just we'll get it mapped within a day of being able to walk down the road!

If you read the bottom of my Corwall blog post you will see I just used Kosmos to display name:kw.

I'm sure I once saw a welsh/celtic map, though I have no idea where this was.
