Hi, I’d like to participate too. My topic ideas: using external models in OSM (why yes, why no), how to guess objects height (high bridges, more bridges cross-over, rivers flows always down etc.), how to handle terrain properly (large objects on rough terrain, road crosswise down from hill), how to tag horizontal objects in different height (for example horizontal bridge under which is slowly decreasing terrain). Date and place is ok for me 
It’s great that so many people are interested in this!
I will definitely try to participate. As far as I can tell now, any weekend in March should be ok for me.
The meeting is a great idea!
I will also try to participate. At the moment every weekend in march except the first would be ok for me.
Possible topics/participants etc. should from now on be added to the new Wiki-Page:
http://wiki.openstreetmap.org/wiki/2nd_3D_Workshop_Garching
There is also a Doodle poll on the date:
Would be up for this depending on what it covers. I’m a long way from Germany (S England) so might be tricky to get there but would like to come if I can. My specific interests are 3D countryside data visualisation on Android or WebGL.

If I understand you all right, then the most of you will visit the FOSSGIS conference, right?
So from 20-22.03 in Dessau.
But than it would make sense to do it directly 2days before or after this conference and of course in Dessau, doesn’t it?
Hi there,
we can also do this in frankfurt/offenbach.

If we decide for Garching: I think it woudn’t be a problem to get a room at the university.
Hmm as to the doodle vote, the most are interested in the last weekend at 24-25.03. which would be one day beyond the FOSSGIS conference in Dessau. So changing the location?
If I understood Marek right, it is for personal reasons only possible for him to do it in Garching. Also, the organisation there would probably be the easiest, since we already have at least two suggestions for workshop rooms as well as experiences from the first workshop.
Of course a location more central in Germany and closer to Dessau would have its benefits too, but do you (!i!) have any concrete plans for organising it somewhere there yet?
No, and if Marek isn’t attending to FOSSGIS (I thougth he would join this conference), we will do it of course in Garchingen. I just tried to keep my journey as short as possible
Hi, I would like to participate at the 3D Dev weekend. I did not spend much time with OpenDEM.info because I was and I am busy with the processing of bathymetry data for OpenSeaMap (openseamap.org).
For a long time I want to test some ways to derive high precision height data with low cost DGPS and GPS Barometers. I hope I could present some results in march at the weekend.
Good to know you on board Martin
Prof. Sankowski, Head of OSM Staff from TU Lodz, can participate before 20.03. I think 09. - 11.03.12 is ok…
Please add his favourites to the Doodle link, so we will get an good overview.
Currently it seems to be a lot of people. Great! 
Ok friends, after a discussion with Marek, we picked the weekend from 17. -18.03.2012. Sadly there is always a date where somebody is missing, but we guess this is a good solution for everybody that likes to visit the FOSSGIS afterwards.
Now we can enter the next steps:
-add ideas for topics that you think should be discussed
-add if you want definitly join this workshop (as we have to rent rooms, but there is still time)
-get room for the workshop itself (Marek?Saerdnaer?)
Ok, so I think this will be a nice metting and we can present interesing results, maybe already at the FOSSGIS
Hi everybody, hope you had all a good new years eve 
Please try to decide within the next weeks if you can come, as we try to get some accomodation there, so we need the number of guests.
Hi, I’m coming, definitely.
Hi everybody, there have already been a lot of suggestions what we could do and talk about in Garching. A few of us have now created a first rough draft for an agenda in the wiki:
http://wiki.osm.org/2nd_3D_Workshop_Garching/Agenda
It’s based on the ideas for topics from the wiki page and previous forum posts. But be aware that this is just intended as a starting point for discussion. So is there anything missing that you would like to do, would you prefer to organize things differently, are you interested in the topics currently on there at all?
I like the topics on the agenda, but would suggest to switch the days and start directly with a tagging discussion for a basic tagging scheme. To me this seem to be the most important reason for our meeting, so it should be #1? What does the other say?
