How much is too much? about 2 months ago

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

Reflections on 10 years of a changing Open Source Map 12 months ago

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 over 1 year ago

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:
Disclaimer I'm the current maintainer for the project.

Alternatively there is Moonphase which runs in System Tray. It's a C++ program.
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 over 1 year ago

A few people use man_made=village_pump.

How many POIs does OpenStreetMap have? about 2 years ago

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] about 3 years ago

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 over 3 years ago

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 almost 4 years ago

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 almost 4 years ago

Very interesting.

I remember some on Porlock Hill, UK ( - 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 about 4 years ago

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


Creating/improving MTB paths at Medvednica mountain about 4 years ago

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 about 4 years ago

Interestingly another low bridge incident:

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 over 4 years ago

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's Id rather than the version!

1000th Edit over 4 years ago


Here's to the next 1000 edits!

All the best.

Another new MapRoulette challenge: Suspected Missing / Wrong One Way Streets over 4 years ago

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.

Am I the Only One... over 4 years ago

Yes definitely.

I've taken to using my SatNav all the time when driving/being driven - mainly for recording random things seen whilst out and about - rather than for routing instructions (generally I know where I'm going!). Alternatively sometimes I video it instead but I don't have a high def device only a cheap £40 one.

It helped when I learnt how to actually create a waypoint on the SatNav - for a Garmin Nuvi255 - just press and hold down on the screen saves a point where you are and name it.

Presently I seem particularly addicted to spotting historic milestones.

Unfortunately they're hard to spot (especially at night!) and on drive (or cycle) by you never have time to see the description on them.

Finding the sections that speed limits apply to is also one of my aims. Often - if I remember - I'll check the speed limit map of where I'm going - to see if it needs improvement.

Elevation almost 5 years ago

Cool map styles.

It's always interesting to see new cartography efforts,

cleanup monitoring_station/measurement_station about 5 years ago

Seems generally sensible to me.

The proposal itself mentions amenity=clock, so one observation is why use display:analog=* instead of display=analog (and of course likewise for a digital display)?

NB for a clock the display is always implicitly at least yes, otherwise why map the clock at all :)

Is it a precedent already set that should be followed?

SOTM13 over 5 years ago

Me too - even if I said I was going to do this merge for my locality ages ago.

Although I still have my own collected data (of various other things) to process first...

GPS Traces over 5 years ago

Note that GPS_Editor applies a constant time diff to each point. The time difference between points is kept - thus calculating speeds between points is still viable - and could point to where one has exceeded the speed limit.

However post calculating 'instantaneous' speeds from GPX tracks is not reliable since the standard only has an accuracy rounded to the nearest second. Often my GPX tracks from a Garmin Nuvi saving every second means I can get speeds over 100mph, when otherwise going slowly (or a spurious point)!!

Averaged over a several trackpoints should give a more robust speed value - and hard to deny that would be due to spurious points (especially if a median or modal average is used).

I don't know if the OSM Traces API will allow all trackpoints having the same timestamp - as that would be the only way to remove speed inferences. According to - it says "trackpoints must have a valid timestamp", thus setting all points to 01/01/1900 could be feasible.

Unfortunately it will not help people trying to process these files to gather speed statistics ;)

NB2 that GPS_Editor is Windows only.

Goes off to consider adding some kind of Anonymize Time function to Viking ( which I maintain...
