Teaser for my OpenStreetMap-Project

Dienstag, Februar 17th, 2009

As I got stuck in Bulgaria, looking for flat-mates, I continued my work on my OpenStreetMap-Project, I was mentioning earlier on my blog (in fact I was not talking about this project since beginning of November).

As I already said, the OpenStreetMap is the Wikipedia of geographical data. The data is collected by volunteers or imported from free data sources (e.g. gouvernmental data if available or free satellite images). In Austria a company – plan.atdonated their data, as mapping is not their main business anymore. This improved the Austrian part of the OpenStreetMap greatly, especially on the countryside (although the import is not finished yet).

My project consists mainly of two parts. The first – and main part – is an interface to browse the available information in the OpenStreetMap. E.g. if you are looking for a pub or the nearest fuel station. But this is not the part I want to talk about this time.

The second part is an improved rendering of the OpenStreetMap. I’m not very satisfied with the default rendering, it looks very pale. I decided to make it more flashy. Additional various overlays can be displayed, e.g. the routes of public transportation (which none of the default renderers of OpenStreetMap do yet).

Attention, technical details: I’m using Mapnik as render engine, the same as the default view of the OpenStreetMap uses. To make developing of the new style easier, I’m using Cascadenik, a kind of CSS for Mapnik.

As I don’t want to announce my project here (it’s still quite buggy and slow), but I want to talk about it, I will show you some example renderings:

In the first example you can see a part of Bulgaria. As you can see the country borders are clearer, and the names of the Cities are displayed in the country language and in the English translation (as available).
In the second example you can see the surroundings of Schottentor in Vienna. Buildings have different colours, depending on their function and a little border.
The last example shows the inner city of Graz with an overlay of the routes of public transportation.

I’m busy developing on my application, I hope to be able to show you more of it soon.

Revolutionary Timişoara and travel back to Sofia

Sonntag, Februar 8th, 2009

Finally I arrived in my (nearly) last stop of my travel – Timişoara. It’s the second largest city of Romania and – at least Geographically seen – the most western city of Romania. It has a large city centre with several pedestrian zones and squares, orbited by parks and on some parts by the river Bega. Around the city centre you have the typical suburban settlements of Communist era.

Again I spoke most of the time German, my CouchSurfer there is working as translator for German to Romanian language. And we even visited a performance in the German National Theater Timişoara (Deutsches Staatstheater Temeswar): „Alles zu seiner Zeit“ by David Ives.

The most interesting and touching thing I’ve seen in Timişoara was the Archive about the Revolution in 1989. Timişoara was the first city to protest against their leader Ceausescu and it was also the first city were the first people died. The director – who was veterinary before the revolution and got badly wounded – loves to talk and show you around. During a movie about the revolution and in the gallery showing the works of children after the revolution, I nearly started crying. Don’t miss it, if you ever come to Timişoara. I couldn’t find a homepage, but if you want to learn more about the revolution, I can recommend you this page.

After Timişoara I had to find a way back to Sofia. It was not so easy, there’s only one bridge between Romania and Bulgaria, in the East of the country, options would have been to go over Belgrade (with a break of 12 hours) or with a ferry between Calafat and Vidin. I finally decided to go over Bucharest, which took me 18 hours and additionally 5 hours in Bucharest which I used to visit the Museum of Peasants, which was really nice (although more English or German descriptions would be nice). The even have some old wooden houses and an old wooden church on display.

Romania was an interesting place to visit. There are still many places to visit – the Danube Delta or the northern parts of the country, which should more rural. I will for sure come back. Here you can see a route of my travel (Data by OpenStreetMap):

(I also made a map like this for our travel through Macedonia)

Being back in Sofia, I got a message from my friend who should visit me on Monday (which was my reason to come back to Sofia), that he has to cancel his visit. So I have to go traveling again! Next stops will be Kosovo and Albania. First I thought about leaving Monday morning, but my new flat-mates told me they can’t afford the rent and will move out at the end of February. As my other flat-mate is not in Sofia for most of the month, I have to search for flat-mates now. But the new Erasmus students are arriving, so it will be easy to find people.

On the way to Timişoara: Alba Iulia und Roşia Montană

Freitag, Februar 6th, 2009

My last stop in Romania shall be Timişoara, but before I was recommended to go to Roşia Montană.

My CouchSurfer gave me a ride to Alba Iulia (she had to go there from her work), which is a not very nice city. It looks as urban development just happens there, without noticeably structure. The interesting thing: There’s a huge fortress from the 18th century, shaped like a star. Most of it is unused, and when I was walking through this place I started dreaming about a festival. It would be a great place with all these backyards and big places. Imagine stages, rows of tents and stands selling various goods.

Roşia Montană is a mountain village with gold and copper mines, which were exploited in antique times for the first time. During industrial revolution it became a wealthy place, many workers came there and populated the area. Unfortunately it all went down in the 1970s under communist regime. At the moment it’s a sad place with deserted houses, unemployed workers and aggressive stray dogs. But underneath you can still feel the beauty of this place, every church has it’s own place of worship, the workers‘ buildings are ornamented and it’s situated in a mountainous area with interesting rock formations.

In the last years Roşia Montană got some publicity, as there is one Canadian company, which is trying to built a new mining project (since 11 years). Especially the young ones fear, that the project would ruin the place. On the other hand the company (using fancy buzzwords like ‚Sustainable‘, ‚Ecologic‘, ‚Community Process‘, …) promises to clean the place (some of the streams are already heavily polluted), bring new jobs and develop tourism. Tourism is also the option for the people opposing the project, but I don’t know where the money should come from – you need some huge investments to renovate the place and make it better accessible. I was talking to „Pro Roşia Montană„, a non-governmental organization, supporting this project. They say, they would support any project, because as it is now, the people can’t survive there. But they are also thankful for the opposition, at least the company had to bring strong arguments and to think about alternatives.

In Roşia Montană there’s even a small hostel, managed by a young couple. They are nice, and it’s a good place, so if you ever happen to come to Roşia Montană, I can recommend to stay at there place (It’s situated 800m back the main road from the main square and called „La Gruber„). I was the only guest (in fact, they were really surprised, that somebody is coming), but they said, that in summer it’s usually full. They also oppose the project, in fear, that the company will ruin this place. I’m sure the hostel would make it, it’s a small place, and there will always be some people going to strange places.

I was happy to leave this place after a night, but I will follow news about it, I got interested in it. I hope it interested you too :)

Fortified Sibiu and churches

Mittwoch, Februar 4th, 2009

I already told you, that my next stop is Sibiu (german: Hermannstadt), former Cultural Capital of Europe in 2007. If you expect all this modern things that happened and (partly) stayed, like in Graz, you might be disappointed, you can’t feel it. But the money in Sibiu was invested wisely, the centre has been well renovated and a huge pedestrian area has been developed. And it’s definitely worth. A short abstract of the history of Sibiu: Sibiu was founded in the 12th century by German settlers, but was destroyed by Mongols a hundred years later. Only about 100 inhabitants survived, who started to rebuild the town, but this time with heavy fortification. Soon Sibiu was wealthy again. As this region was threatened by many enemies, many castles and citadels were being built – like Braşov and Sighişoara, I visited before. Also many churches has been fortified, so called „Kirchenburgen“ were being built. And there are many, at least 300, maybe up to 700. About 140 still exist, but many need renovation.
In Sibiu I was couchsurfing again. This time it was pretty interesting, because my host was working for the protestant church, her current work was a EU proposal for the renovation of 18 of these fortified churches. I could even help a little bit. Unfortunately I didn’t meet one of her working colleagues (an urban planner from Berlin), who was responsible for the renovation of Sibiu for the year as Cultural Capital. I would have liked to hear some experiences from him.
So, back to my travel, I’m sure you want to see some pictures. Historic Sibiu has two parts, the Upper Town (for the merchants and rich) and the Lower town (for the workers). The Upper Town is arranged around three huge squares and has heavier fortification. The Lower Town has smaller buildings and narrow roads, crossroads are often enlarged to little squares. Everywhere in the historical centre, you have historical buildings (15th-18th century) and several churches.

On the last day in Sibiu I went to see some villages around Sibiu and two fortified churches. I wanted to take the tramway (there’s only one route left from the Southern end of Sibiu to one of the villages outside, Răşinari), but unfortunately I would have need to wait two hours. But there are some people who have some kind of informal collective taxi service, I could take one of these (for 2,5 Lei = 0,60€). From Răşinari (german Städterdorf) I followed a hiking route to the next village, Cisnădioara (german Michelsberg). I couldn’t find all parts of the way, but finally I managed. I had some really impressive views on the way. In Cisnădioara there’s one old Romanesque fortified church on top of a hill, with a simple wall around. Then I walked to the next village, Cisnădie (german Heltau), which is actually a little town, with another, bigger fortified church.

I hope I didn’t bore you with my tale about churches, but I found them rather fascinating. Maybe you want to see them yourself? Take somebody with you who speaks German or Romanian, there aren’t many people who speak English in that region (and texts are often only in Romanian and German, maybe a short description in French in English – even on the signs, which were erected for 2007).

Mighty Sighişoara and Mediaş

Montag, Februar 2nd, 2009

I decided to spend one night and one day in Sighişoara (German: Schässburg), which is a UNESCO World Heritage Site (I think I should start to compile a list of World Heritage Sites that I’ve already seen). It’s a little town with 30.000 inhabitants, topped with a citadel (a kind of inhabited castle). The citadel was built in the 12th centry by German settlers, and still looks like a medieval place.

On the way to Sibiu I had to change trains in Mediaş (German: Mediasch). I didn’t know what I can expect of this city, as it was not covered by my guide book, but I decided to make a little break. My worst fear was, that it’s a city, built during communist times, only with grey block buildings. I was wrong, it’s another old city, built by German settlers, with a fortified church in the centre (more about fortified churches in my tale about Sibiu).

Sorry for my short description, next – about Sibiu – will be longer. Promise. Enjoy your time!
