My workflow method...

Regarding Viking usage you can override the built in default browser opening mechanism (I’m assuming you’re using a Linux version since you’re using gpscorrelate) as follows

  1. When Viking is not running edit your ~/viking.ini file to add this configuration option: use_env_browser=true

  2. Set an environment variable ‘BROWSER’ to something like ‘firefox –new-tab’.

  3. Run viking, which should then use this $BROWSER value to launch web things.

You can even have quite a complicated BROWSER string, e.g. for me I can make it run a specific version of Firefox with a specific profile, such as on the command line:

BROWSER="/home/rob/Downloads/firefox/firefox -P 'Nightly' --new-tab" viking

HTH.

PS Unfortunately this is currently not mentioned in the Viking manual.

Freedom of Information requests

In case you are not aware about Robert Whittaker’s site… one of the OSM elements concerns defibrillators:

https://osm.mathmos.net/defib/

With maps of data and links to FoI requests.

HTH.

Creating a Map for a Garmin Edge 520

NB These maps are not routable: add the –route option in the mkgmap command.

Displaying accessibility information in map icons

It would be interesting if these could be generated programmatically and more importantly then used directly within carto/mapnik somehow. Mapnik supports some level of .svg for Point/Marker symbols, so perhaps another level of code generation. Thus no doubt much more complicated to get it working for the first time if no-one has done something like this before.

Displaying accessibility information in map icons

That’s a lot of pub icons!

Did you generate these manually?

How much is too much?

Probably would be better if all the swimming pools were tagged as private though.

Reflections on 10 years of a changing Open Source Map

A great write up for your OSM story. Definitely need a +1 / :ike / thumbs up for this diary entry. Here’s to the next 10 years.

Now I get Pushed Down Some Stone Stairs

Regarding phases of the moon, I recommend SunCult, which runs as a plugin in Firefox.
It can show when the next full moon is.
Install it via Mozilla’s Add Ons extensions.
The source code (in Javascript) is available: https://sourceforge.net/projects/suncult/
Disclaimer I’m the current maintainer for the project.

Alternatively there is Moonphase which runs in System Tray. It’s a C++ program.
https://gitlab.com/alanwise/moonphase
NB Can be hard to track down pre-built binaries though.
The current version doesn’t support showing when the next new moon is although it’s on the wish list.

There are other programs out there too, but these are the ones I use.

First Gedling Water Pump Mapped

A few people use man_made=village_pump.

How many POIs does OpenStreetMap have?

Some other POIs:

Nearly 7.4 million individual trees

0.5 million historic=memorial/monument/wayside_cross shrine

over 0.4 million peaks

Improving the OSM Map - why don't we? [11]

Indeed, normally within a city: place=suburb or place=neighbourhood could be more appropriate, which themselves may be governed by some kind of administrative body.

The key point here is that a hamlet is isolated; whereas suburbs and neighbourhoods form continuums within a larger administrative area (i.e. a city).

If they are trying to indicate even more precise areas, there is place=locality; which is probably more nebulous and less likely to have a formal administrative distinction, but more akin to how people would name the area they live in.

New road style for the Default map style - the first version

Disclaimer, I’m British so I might be biased towards the current OSM Standard styling.

I’m not entirely sure if changing the major road styling is an optimum strategy. Given the current styling has been in use for 5+ (?) years, many people may be used to how the standard map looks. When was the last major change to the style?

By all means create alternative styles, but to enforce such a high level visible change could easily create a lot of confusion / annoyance for many users.

Funny highway shortcuts with the new routing feature

Rovastar: I suppose one could map the physical barrier bollards/posts - but I agree the access rights are not for general public use and thus need to be defined better.

I probably would have used access=private, maybe adding emergency=yes would be even better. One assumes Emergency services could do such daring 180 degree manoeuvres.

Learn-a-tag: highway=escape

Very interesting.

I remember some on Porlock Hill, UK (http://www.openstreetmap.org/#map=17/51.20620/-3.60374 - not currently mapped) and some others else where from journeys many years ago but unfortunately for remote mapping via aerial imagery is difficult / not possible as these areas tend to be covered by trees.

OS Locator update 201411

Note that gpsbabel can convert .osm files into GPX files.

See: http://www.gpsbabel.org/htmldoc-development/fmt_osm.html

Creating/improving MTB paths at Medvednica mountain

I use Waymarked Trails to view all kinds of outdoors routing. There is a specific version for MTB:

'We Fit' FAIL, Google FAIL, OpenStreetMap WIN

Interestingly another low bridge incident: http://www.bbc.co.uk/news/uk-england-norfolk-29512618

http://www.openstreetmap.org/way/24569301

The height limit is marked in OSM since 18 November 2013

Neither of the BBC stories mention the Sat-Nav make/data provider.

Water in OpenStreetMap

An excellent MapRoulette challenge - thanks.

[Although one could argue for the case of large elevation change (e.g +200m) or ways from the sea - could be automatically fixed by a bot].

It would be nice if the link to edit with Id used the main OSM.org’s Id rather than the OSM.us version!

1000th Edit

Congratulations.

Here’s to the next 1000 edits!

All the best.

Another new MapRoulette challenge: Suspected Missing / Wrong One Way Streets

Are you using Telenav GPS traces (so presumably only driving traces) or OSM traces?

Otherwise for OSM traces one would need to filter out traces from walking which presumably can go in any direction, for example perhaps just discarding traces with slow average speeds when performing vehicular type analysis.

Can you also enlighten us on the ‘confidence level’ methodology? (or mention in your SOTM talks)

Thanks for all the improvements to MapRoulette.
