Which camera for capturing 'Street View'? 18 days ago

For using on a bike, I think the GoPro is a bit smaller and a better shape. Plus there is a wide range of mounts available. I think the Virb has some sort of adapter to attach to GoPro mounts, not sure how well that works.

For GoPro battery life, it seems to depend on the model. I think the more basic models (white or silver), have longer battery life than the black. The GoPros can be powered from a USB supply, so for in car you could plug it in. Or you can get a battery bacpac, to double the battery life.

The built in GPS on the Virb could be very useful for geotagging photos. Yes, you could use a GoPro plus a separate GPS recorder, but you have to make sure the time is set correctly to make it accurate.

CAPTCHA problems in the Wiki 2 months ago

Just testing now: It seems to be a problem with Template:Relation. http://wiki.openstreetmap.org/wiki/Template:Relation

All of the links on Template:Relation are already on the whitelist. And adding those links on their own works fine, without a captcha. But adding the template requires a captcha.

Postcode map 4 months ago

That postcode map seems to show exactly the same thing for the OSM layer and the NPE layer. So one of them must be wrong. I suspect the option for OSM postcodes is actually just showing the NPE postcodes.

Couldn't Save Changes 4 months ago

And to avoid this, save often. Maybe every 5 or 10 minutes.

Especially if it is a busy area, with several other people editing there. Because there is a high chance of someone else editing the same things as you, causing a version conflict.

My new wishlist 5 months ago

There have recently been several threads on the Talk-GB mailing list about whether to map the effects of the floods in England, and if so, how. Most people seem to agree with not mapping them, at least not using 'normal' tags. Though a few people have mapped floods as natural=water, and closed roads as access=no etc.

Worth considering is how permanent the effects of flooding will be. ie if you map a road as closed now, will you resurvey it and update OSM if it reopens next week? And some OSM maps only update infrequently, so any changes to the data might be around for a lot longer.

Also, this doesn't really need the Humanitarian OSM Team, because there are already plenty of active mappers in most parts of the UK.

StreetMap.co.uk uses OSM 6 months ago

It looks like pretty much all of the map at that zoom level is from OSM. ie roads, paths, buildings, parks, forests etc. Not sure how up to date it is, it might be missing some houses I mapped a few months ago.

Yes, it does have some interesting cartography features. eg abbreviations for streetnames. It also seems to be displaying 30mph speed limits with grey roads.

Looking for android gpx logger for POI collecting 8 months ago

You could try OSMtracker. It can record a GPX track, and has a button on the screen for for voice recording. Though I don't know if it will work with the handsfree button. You could request this feature if its not available. https://wiki.openstreetmap.org/wiki/OSMtracker_%28Android%29

What does the path say? 9 months ago

So should highway=cycleway only be used for smooth/paved paths you can cycle along?

It is currently also used for mountain bike trails with rocks, mud and steep drops etc.

What does the path say? 9 months ago

What about purpose built mountain bike trails?

And by "some quirk of arcane legislation", many countries have a right to cycle just about everywhere. its just England and Wales with arcane restrictions.

Remember to map post-boxes 10 months ago

I agree with this, its worth mapping postboxes. There's still quite a few unmapped in the UK. It seems Royal Mail don't actually know where they are, so OSM may be the best available map of them.

Plus you can take extra details for the type of postbox, and the royal cypher etc if you want, see http://wiki.openstreetmap.org/wiki/Proposed_features/Extend_post_box

Also Post Hoc is a useful tool for finding missing postboxes or possible errors. http://robert.mathmos.net/osm/postboxes/

Bicester to Upper Heyford 10 months ago

You could try Cyclestreets. http://www.cyclestreets.net/

Its good for getting ideas for cycling routes. It has options for fastest or quietest, so you can try them out and see how they compare.

Collecting Addresses, What I've learned 11 months ago

If you have an Android phone or tablet, try Keypad Mapper. http://wiki.openstreetmap.org/wiki/Keypad-Mapper_3 It is very good for collecting lots of house numbers quickly. It will record the numbers as an .osm file, which you can load into JOSM, then add numbers to buildings etc. It works fine without a data connection, so long as you can get a GPS signal.

How to download SOTM US 2013 videos? 12 months ago

They are available to download on the Internet Archive. https://archive.org/search.php?query=sotmus2013

GPS Traces about 1 year ago

Or you can set the visibility options for the traces. See http://wiki.openstreetmap.org/wiki/Visibility_of_GPS_traces

If you set a trace as "Trackable", then it won't be linked to your account.

Making OSM data mor compact about 1 year ago

Landuse areas should not (usually) share nodes with roads, tracks, paths etc. The way for a road represents the centre line of the road.

So if the road shares nodes with a field, then you are saying the field goes halfway across the road. If you have a field on one side of the road, and a forest on the other, then there is a gap in between them. The road does have the width, even if it is only mapped as a way.

Though if you have farmland with a meadow right next to it, nothing in between, then they probably should share nodes.

A Greek nightmare in road classification about 1 year ago

The forum is here: http://forum.openstreetmap.org/ It does have a section for users:Greece, though I'm not sure how active it is.

Or details of mailing lists here: http://wiki.openstreetmap.org/wiki/Mailing_lists It looks like there isn't one specifically for Greece. You could try the general "Tagging" list.

My 10 most useful OSM links over 1 year ago

A few more links I find useful:

http://open.mapquest.com/ - does car, bike, pedestrian routing

http://www.cyclestreets.net/ - very nice for planning bike routes (UK only)

http://garmin.openstreetmap.nl/ - if you have a Garmin GPS device, this is probably the easiest website for adding OSM maps.

Editing: OSM's website vs Quest Map Open? over 1 year ago

For using Potlatch 2 on openstreetmap.org, press M to hide the left panel.

Wierd looking streets, what to do? over 1 year ago

Send a polite message to that user, asking what they are doing, and what sources they are using. And explain that OSM is a map of the real world, and that they shouldn't be adding things which don't exist.

Though it looks like they haven't edited in over a year, so you might not get any reply.

You could ask on the Talk-US mailing list, to see if there's anyone familiar with the area.

Updating housing site no 5... over 1 year ago

Or you could set up Mapnik to work in the OSGB projection. There's instructions here, but it look a bit complicated: http://wiki.openstreetmap.org/wiki/Mapnik_GB_Projection

Then you could use Mapnik to generate SVG images.
