New Year cycling

With the extra eating over Christmas, I’ve started out on my (evening) cycling again. On the 1st of January I headed out East and got to Rochester before getting on the train home. On the way near to Ebbsfleet International I found a rather interesting sign that I just had to take a picture of.


After uploading it to Flickr, I check that I had geocoded it right, by looking at the map on Yahoo. I got very confused. It seems that Flickr need to start using OpenStreetMap data for London. Yahoo don’t that the new Channel Tunnel Rail link and some of the new roads around Ebbsfleet International, though they do have the location of Ebbsfleet International. Compare Yahoo with OpenStreetMap.

UPDATE: Looking further it seems that Flickr are using older map tiles compared to, but appear to be the same tiles as used in Yahoo UK


On the way I was testing out some routing using osm data, and found a few data bugs. One very important one being a primary road that goes through a tunnel, which doesn’t allow cyclist, pedestrians, nor horse drawn carriages, hence routing cyclists through it shouldn’t be done.

On the 2nd day of the year, I took the train down to Caterham, which is just inside the M25, and then cycled back up mostly using the NCN21. On passing through New Addington, I got a little mapping done on the way, mostly new roads that are completely missing from OSM, there is a lot of mapping required down there. Anyone up for a mapping party?

Weihnachten 2008 in Deutschland

This year for Christmas I went over to Germany to see some family I haven’t seen for 11 years. I really should learn some more German, so that I can speak with my grandmother, rather than needing my cousin, to translate for me. She learnt more English than I learnt German, though she needs to learn it for her university course.

While I was there I got the village Singhofen mapped, all on foot, and often freezing temperatures. At least it was dry, and I had my big duvet jacket, so didn’t notice the cold as much. There are plenty of quiet roads that lead off to the neighbouring villages, and some of the finer details that still need to be completed. Hopefully next time I go, I’ll have a bike, which will make it rather a lot faster to do the surveying.

Some people think that Germany is complete, in fact most of the small towns and villages have been forgotten about. Many of them are missing any roads going to them. The Germans are organised enough to have a list of places that need mapping, with an accompanied slippy map.

To get there I used the Eurostar from St. Pancras to Brussels, there I changed to Thalys to Köln, where my cousin and her boyfriend picked me up. While I was in Brussels, I had an hour to kill so went out for a quick walk and found some unnamed streets. I also found this cart that had fallen on the  tracks in the station:


I have a 44MB NMEA (27MB GPX) track @ 5Hz of my journey back, with the exception of when I was on the DeutcheBahn train from Koblenz to Köln, which seems to be like the UK’s Virgin trains in their expertise in blocking GPS signals.

One interesting thing I found outside Köln train station was that there was a lot of bicycles standing there with a lock between the back wheel and the frame, and not locked to anything fixed to the ground.


Happy new year to all.
