Swiss blogs map

It started with a blog entry by Matthias and continued with some discussion on the last "Bloggertreffen", now I did some first implementation with worldKit: A map of all Swiss blogs (and surrounding area), which have ICBM entries.

I took the data from GeoURL, choose a point somewhere in the middle of Switzerland and let me display all blogs 200km away from that center point. Thanks to GeoURL's RSS export and worldKit's RSS import, it was a really simple task to have them all displayed on the map.

The points are a little bit off on the map, since the map is aligned to the Swiss Coordinate System, which is not totally parallel to the longitude/latitude system worldKit is based on. The satellite image (provided by swisstopo) hasn't the greatest resolution either, if someone knows of any better (freely available) map, please tell us ;)

Maybe blog.ch will integrate something like that one day. With its own geodata parser and not relying on GeoURL. Matthias seems at least interested to do something like that.

Addition: The RSS file, which has to be loaded by worldKit is approx. 170kB big. It will take some time, until the dots are displayed.

Nice! But I'm not here :(
What's ICBM and how to add it? Tnx.

http://geourl.org/add.html explains it quite nicely

Cool stuff!! I completely forgot about the geourl rss export. As you know, I'm working on something like this. The geourl data is in some cases woefully outdated and doesn't cover only blogs, but I guess I can use it to supplement my blog.ch data. Saves me lots of manual labor.

FWIW, here's my version; all geourl sites in a 300km circle around Berne (the heart of Switzerland, haha).

- There are indeed lots of sites that aren't blogs, but it's fun anyway!
- Blogs with similar lat/long are all sitting on top of each other. A little function that creates a nice cluster would be useful here.

You'll probably win the map-race as you're a lot faster with PHP than I am :-).

Hehe, the map race is over for me. I had my fun and I don't plan to develop that further ;) You're the master of the Swiss Blog data, so I let you work on it. Of course, if you need help with PHP, just ask.

Master of Swiss Blog Data, now that's a title to remember ;-)

My latest script (still at http://blog.ch/maps/ ) compares the geourl data to my blog.ch data and finds 71 matches, which I show on the map. Now I only need to come up with the geo data for the other 280 blogs... or get everybody to register with geourl.

As for PHP: That's an offer I can't refuse! Do you have an idea how I could massage the geourl data so all blogs in one city kinda huddle around the city without actually sitting on top of each other?

Let me know if there's any way I can provide the data from GeoURL better. :-)


- ask

chregu, 01.06.2005 10:16 CEST

matthias: mmmh, you would maybe have to define circles around the big cities, then find out, which points are in these circles and draw them on that circle. MySQL 4.1 has some geo-spatial features which should make that easier docs). Plus some simple trigonometry in PHP should make that possible. Great would be some lines from the points on the circle to the actual location. But maybe not needed as long as we don't have more accurate maps (you could just link to multimap for accurate maps, for example). How to do that in real, no idea ;)

Ask Bjørn: Your data from geourl are perfect, I didn't miss anything.

Matthias, 01.06.2005 10:57 CEST

Ask Bjørn, I agree with chregu: The RSS is good, I don't need anything else. I just needed to filter out the sites that aren't blogs. And while I'm at it: Thank you very much for bringing geourl back to the world.

chregu, I wish I had paid attention in math classes... and the geospatial stuff doesn't look easy to me either. But I'll find a way... a real programmer will probably faint at the sight of my "solution" :-)

Nice idea these blog maps - Perhaps a map title (as with any website) would make them more readable.

P.S. Why is my GeoURL'ed page not on the map?
It was and is there http://geourl.org/near?lat=47.2240&long=8.8181 already for some time -- Geonick (www.geometa.info)

@geonick: Cause your search engine is not a blog and the map of chregu would only display blogs.

Von der Idee die Position von Webseiten auf einer Karte anzuzeigen lassen war ich schon immer sehr begeistert. In letzter Zeit gab es immer wieder Versuche Karten und Positionen von Webseiten zu verbinden.
