I didn’t notice any press coverage so far. Only Margot Wallström’s blog directed my attention to Debate Europe. Surely a great idea towards the right direction. Take part and share your view of Europe’s future.

What if Apple presents on April 1st an Origami like product instead of the rumored 13.3 MacBook? Frankly, I would highly welcome such a device since I’m looking for something between PDA and notebook…
In contrast to several media scare stories about avain flu you’ll find here a well edited H5N1 distribution map by Declan Butler. A great example of how to use Google Earth for information dissemination.
As spring took its time to arrive in Austria and the unfriendly weather forced me to stay at home I started playing around with the Google Maps API again. A few weeks ago I saw those nice underground maps for London and Madrid and thought that I’ll create one for Vienna.
All the necessary information like positions, line numbers, station names, etc. are stored within a XML file which I can access by JavaScript and overlay it to my Google Map. Of course it would be possible to pull all that information out of a database too, but for about 40 stations it would rather be an overkill than useful. I thought about extending the map by tramway and bus stations. Then a database solution would make sense as you’ll probably get a few thousand stations to manage.
Additionally I put links to Flickr to the stations, all stored in my XML file. If I found a station relevant photo on Flickr it’ll display within the information bubble directly on the map. A link to Flickr search gives you the photos which contain “Vienna station name“. If you have a photo on Flickr of a certain viennese underground station, just add the appropriate station name and Vienna to its tags, title or description and it’ll be found by this search string. To narrow the results it would be great to have an underground station specific tag like subway or underground.
I think it’s a nice feature. If you don’t know the place you get an image what it looks like, or what the station looks like. Underground photos can be really interesting, frankly, I somehow like them. Once position information is an EXIF tag by default all this search-by-name will be redundant and some strange robots will automatically map your holiday photos. But till then, human beings have to apply names to places.
The points (“U”) in the map only represent the “center” of the station. I didn’t map every single exit. That would be something for my ToDo list.
All in all it isn’t a big deal but I think it’s nice example for testing and learning webmapping APIs. Once ArcWeb SVG Viewer offers some detailed data for my region I’ll probably apply this map for their API. Actually I’m pretty looking forward to try their JavaScript/SVG thing.
Update #1:
More details about Vienna’s underground network you find at UrbanRail.net.
Update #4:
Improved photo search.
We have a german proverb which might could have made it up to the Canadian Record Industry: acknowledgment is the first step towards improvement. (via /.)
Today in a radio show the question why people drink much more tomato juice in airplanes than on the ground was raised. I noticed the seemingly excessive tomato juice consumption in airplanes already some time ago and was wondering about the reason for that behaviour. Many people noticed and thought the same I guess.
As far as I remember I always asked for tomato juice on the plane while on the ground I only bought like 2 tiny bottles of tomato juice in my entire life. I don’t like it. Maybe it tastes different on the ground. Or maybe it’s a kind of reflection when I’m asked by a stewardess instead of a waitress. I don’t know.
Googling this question brought me, amongst others, this article: “What’s with that glass of tomato juice on airplanes?“: The author argues with the fact that traveling by plane was an upper-class privileg back in the 1950ies, when civil aviation began its success. That audience brought their clubby lifestile including classy drinks like the bloody mary and ginger ale aboard then. Over the years flights became more popular and affordable by a broader public. The costums of the former wealthier passengers stayed in the planes and were adopted by the new emerging clientele. Tomato juice and ginger ale are, following that article, ordered to inhale a bit of the formerly exclusive flair.
That explanation doesn’t work for me. When I first went by plane I really doubt that I ordered the glass of tomato juice because of the noble atmosphere in there. Even if I got upgraded and sat next to a priest of the Vatican who intended to do some polite small talk on our flight to Rome. I saw the stewardess pouring tomato juice in somebody else’s glass and an overwhelming desire for a glass of the same delicious tomato juice just came over me. Before that day I only tasted tomato juice as a part of a bloody mary, keeping in mind that I wouldn’t call this drink my preferred one and I hardly would’ve bought tomato juice without vodka. Since then, since my first flight, I’m always having at least one glass of tomato juice on airplanes.
Another article cames up through Google containing some more statistics. “Tomate im Flug” states that about 3% of all tomato juice consumption in Germany takes place above ground level. That’s quite a lot compared to orange juice with an airplane-share of about 0.4%. The author assumes that passengers consider tomato juice as healthier than other drinks offered in planes and order them because of feeling a slightly upset stomach in the airplane. But why wouldn’t people do so once back on the ground? It wouldn’t came to my mind to drink tomato juice when feeling bad. At least it didn’t until today.
The article goes on with an interesting observation made by airlines while serving tomato juice: the tomato juice snowball effect. The first one is whetting other passenger’s appetite and there is good chance that demand is exploding after the initial tomato juice is served. I guess this explanation would work for me. If not already doing so, I’ll definetely start thinking about having a tomato juice after spotting someone elses glass filled up with a bright red liquid.
However, it’s an interesting phenomenon. Next time on the plane I’ll ask somebody why he/she is drinking tomato juice. Perhaps I’ll start my own little research on that strange human ritual.

Andrea Rosso has posted some amazing details about further SVG development on ArcWeb Services. Due to their REST API, ArcWeb Services already offer some basic SVG output.
Apparently ESRI is just about to enhance ArcWeb’s SVG capabilities and release sort of a SVG ArcWeb Explorer, similar to ArcWeb Explorer based on Flash. Unlike the existing Flash version, you’ll be able to download the whole viewer including all sources and customize it in order to fit your needs. Since JavaScript plays an important role when it comes to interactivity and SVG, he points out that it’ll be quite similarly to a JavaScript API. So it should be fairly straightforward to embed ArcWeb SVG into your applications or create your own mashups.
Another highly welcome detail is that he mentions Firefox’s built-in SVG support in his post. As well the screenshot on his site shows Firefox demonstrating ArcWeb SVG Viewer. If ArcWeb SVG works well in Firefox I assume that it will be truly platform independent, something one could hardly achieve while Adobe’s SVG Viewer was the only serious viewer for SVG (cf. DOM implementations on Win/Mac/Linux browsers for instance).
If you got interested by now in what’s going on with ArcWeb and SVG you should keep your eyes open for ArcWeb Labs (to be opened soon). According to Andrea ArcWeb Labs should give some insights and information on unreleased applications.
ArcWeb Services providing an advanced and easy to use SVG interface means a significant progress for the acceptance of SVG as webmapping technology. You may look forward how this will work out.

Head over to Kerry Coffin’s post to get some more information about ArcWeb’s SVG Viewer (e.g. available widgets, perfomance in Firefox vs. Adobe SVG Plugin) and see a few very promising screenshots!
