If you are an owner of a Garmin 520 device, you may have discovered the device has the capability to use custom maps in the standard Garmin .img format. Unfortunately the device has quite limited internal storage (up to around 100MB) and no external SD card capability.

Storage space can be increased by removing the default Basemap and maps of your choice (e.g. your local area) can be acquired via the excellent [OSM Garmin Maps] (http://garmin.openstreetmap.nl/) website.

Further information about doing this can be found via these blog posts:

• Garmin 520 mapping
• How to install bike maps on the Garmin Edge 520

However consider the needs of the long distance cyclist - such as a participant in London Edinburgh London, the premier Audax UK event - in this scenario the above available maps needed to cover the area being travelled will be too big to fit on this device.

One can use OSM data directly and process the data yourself using Open Source tools to generate a gmapsupp.img file that covers your area of interest. My operating system is Debian Linux so the tools needed are available, of a modern enough version and easy to install via the standard operating system ‘apt-get’ manner:

• mkgmap
• osmosis

Those using Windows or Mac OS’s can run these tools but installation is normally more intricate and one will need to refer to the individual websites for specific instructions.

Overview

My method for generating a suitable gmapsupp.img is thus:

1. Download a OSM data extract in PBF format - Geofabrik
2. Run osmosis to remove and contain only the relevant data wanted for the map.
3. Create the map using mkgmap, using the default style.
4. Transfer to your Garmin device and enjoy.

All these steps can be easily scripted to be able to run with different parameters, such as adjusting the data being used or for a newer dataset.

Recently I have be watching The Prisoner on DVD; and having been to Portmeirion this year to the No.6 Festival, I thought I’d find out where Buckingham Place (as shown in the opening credits of The Prisoner) actually is.

With an eye to view the street as well, I turned to the all seeing eye of No.2^H^H^H, I mean Google. However Google infuriating thinks I mean ‘Buckingham Palace, London’ and centres the map there, no matter how I enter ‘Buckingham Place, London’ even when itself lists ‘Buckingham Place, London’ as one of the options after typing Buckingham Place (and listing Buckingham Palace separately).

OSM to the rescue!

Entering in “Buckingham Place, London” into the search box on the OSM website leads one to the one and only result of Buckingham Place.

Interestingly Buckingham Place is rather near Buckingham Palace, less then 1/4 of a mile away.

Sadly Mapillary’s search is much worse and returns no relevant answers, but currently there are no images of this road anyway.

Be seeing you.

It would be nice if more pubs where tagged with real_fire=yes to determine whether the pub has an active and frequently used fireplace when it’s cold outside.

At the moment this is barely used tag, but would be quite interesting to see it used on a large scale.

I would encourage all mappers to consider this tag value and update any known places - may be including some research this weekend or any other time it’s cold around where you are.

It must be noted that in ‘surveying’ a pub in summertime it can be hard to determine if any fireplace is in actual use during the colder months. One may have to ask the staff or inquire with a local drinker.

There are other websites that list the real fire (among the many) properties of pubs (of course do not copy any copyrighted data), but from my local knowledge they seem fairly inaccurate - seems more like saying they have they a fireplace capability - even though they never or so infrequently use them that it shouldn’t part of a reason to go there.

It may be some time before any pubs with fires are rendered on the standard maps (flaming pint anyone?), but with the new Overpass Turbo it’s quite easy to do a search on even reasonably large areas, such as Hampshire (a UK county size).

Simply like:

<query type="node">
  <has-kv k="amenity" v="pub"/>
  <has-kv k="real_fire" v="yes"/>
  <bbox-query {{bbox}}/>
</query>

Of course this can be improved just to include pubs marked as building areas.

Harry Hill style, gotta have your (waypoint) system:

• Ultravox ; post_box
• Steve Coast ; guidepost
• Eddie Izzard ; barrier bollard
• Frederick Ramm ; ice cream van

But short of trying to invent a Famous Name to a Mapping Feature as an aide memoir, here is my list of waypoint symbols I create (on a Garmin Etrex Legend HCx) whilst out and about on foot or bicycle in England and their meaning:

I finally got around to joining http://help.openstreetmap.org since today (well technically yesterday as I write at night) the weather in the South of the UK has been conducive to indoor activities.

I’m up to 91 points (http://help.openstreetmap.org/users/3300/robbieonsea) - yay go me! But that’s much to self congratulatory for my normal British manners.

One day I may even get around to setting up a picture of myself as an avatar - but for now I’ll leave that to Facebook & Google to join the dots of my various online activities…
