Cycling, Cycling, Cycling

Donnerstag, Mai 21st, 2009

You know, I’m a passionate cyclist. But since my bike got stolen in middle of October, I’m without a ride here in Sofia. I didn’t really miss it, because this place is just not made for cycling.

But, something amazing happened :) A friend of my mother, Nordfried, was doing a cycle tour from Novi Sad in Serbia to Vidin in the very north-west of Bulgaria along the Danube. To go back to their home country (Germany) they came to Sofia and wrote me an e-mail beforehand if I would be willing to help them with train tickets and show them around a little bit. For sure, I like being a guide, I myself always learn something new. After helping with train tickets Nordfried offered me to take his bike – he had just bought it in Novi Sad and has no use for it in Germany. I’m feeling so flattered … I’m very happy about it. But still I’m afraid to use it, because I don’t want it to be stolen again. And I need a good place for the night. First I need a good lock!

Two days later on Saturday, there was an invitation to a „bike parade“ through Sofia, to demand more bicycle lanes. As I have my new ride now, it was mandatory for me to go there. And I was really amazed, I think there were more than 2000 people. I didn’t even think there were so many bikes in Sofia (ok, I’m kidding). Afterwards there was a small party in the „Kolodrum“, a former bicycle arena, but I decided to go to the night of museums with free entrance. I think Sofia needs some more years, but finally it could become a good place!

In the last days I read in my newspaper, that – maybe due to the financial crisis – many more people uses bikes for their everyday ways in Vienna as in the last years. At the most important counting point – at the Ring near the State Opera – there’s an increase of about 25% to the last year. On other points, Lassallestraße, Kennedybrücke and Langobardenstraße the increase is about 50% (more statistics). This is really great news, I hope that the politicians now feel the need to do something (for example find a good solution for the cycle route at the Ring).

Again OpenStreetBrowser

Dienstag, Mai 5th, 2009

As I told I’m gonna present some features of the OpenStreetBrowser from time to time. It’s also a good documentation for the project.

Routes of public transportation

Routes of public transportation are still not being displayed on the main Mapnik and OsmaRender renderings, although they are very important in my opinion. For me this was actually the start of the project, I had planned to make a nice map with public transportation routes. Now they are only an overlay, as they would clutter the main map too much.

There are two noteworthy features: The references of routes sharing the same way get collected and separated by ‚,‘, which looks much better, and stops with the same name get combined and get a box drawn around. Both of these features improve visibility.

Link to Wikipedia

In the OpenStreetMap it’s possible to link to the Wikipedia. The key is „wikipedia:language“, e.g. „wikipedia:en“ or „wikipedia:de“. If such a link exists, the OpenStreetBrowser displays an abstract of the article and an image, when it finds one (it has to be before the first abstract … this is something still to improve).

Stylesheet for the Overlays

The last feature for this time is the newest feature. The styles of the Overlays „Food & Drink“, „Shops“, „Culture & Tourism“ and „Services“ is generated from a page in the OSM-Wiki. So if you find something missing on these overlays, or you have better icons (many objects don’t have an icon or share icons with other features), feel free to upload them there (the new style sheet will be used after the next database reload, so typically after 1-3 weeks).
