WhereCampEU Amsterdam

I am just back from Amsterdam, where I attended the 2012 WhereCampEU, which was absolutely awesome again!

Of course, Amsterdam is a special place and one of the coolest places on this planet. You can't really compare it to any other major city I know about. Amsterdam is just differnt and by this extremely interesting.

Beeing in this extremely interresting environment of Amsterdam, the venues in which the WhereCampEU took place this year were great!

The preconference warm up event took place in the Theatrum Anatomicum of the de Waag Tower. From Henk Hoff we learned about the history of this place in an entgrtaining presentation.

Hi there,

I thought its maybe a good idea to do some blogging again. I still pay a ~9 € a month for my virtual server instance and the domains and nearly don't really use it (except as a cloud storage and backup device)...

The last blog post here is now nearly a year old, writing about the WhereCampEU 2011 in Berlin. Now, I am just back from the 2012 WhereCampEU in Amsterdam, which was again a blast!

It is not that I would not have things to write about, I did a lot of thigs which would be worth blogging about within the last year, but somehow I had no interest to share it here. Maybe this is because of Twitter, Facebook and co., where everything is shared in smaller pieces and makes the blog post obsolete in some sense?

WhereCampEU 2011

WhereCampEU is by far the coolest geo event I know of. I attendet the first WhereCampEU last year in London, which was really fantastic, and this WhereCampEU in Berlin was in my perception even better! The event was awesomely well organized. The venue was perfect, located in one of the coolest neighborhoods of Berlin (Prenzlauer Berg), in the GLS Sprachenschule, a well renovated "Grüderzeitliches" (late 19th century or early 20th century) building I would guess. The sponsored lunch also was of really good quality, never had better food at an conference lunch even the most so called Gala Dinner menues on other conferences would have to hide behind this. ;)

This is a detailed HowTo on deploying a MapProxy instance on Enterprise Linux (CentOS 5.5) for production. I worked this out for the deployment of the CRC806-Database MapProxy instance. It will describe a setup using Apache with FastCGI (mod_fastcgi or mod_fcgid) on a blank CentOS 5.5 amd64, which is also described shortly and more generally (focused on debian/ubuntu) in the MapProxy documentation.

In this tutorial you can find out about, how you get your Sketchup 3D models into the deegree3 WPVS backend.

Be aware, that this is a quick and dirty write down of a CityGMLConverter howto short before the deegreeday, to have a complete WPVS tutorial. This tutorial will be worked out with more detail later on...

The deegree3 DataManager tool will accept your models in VRML or CityGML format. In this tutorial, a method to get deegree3 compilant CityGML out of Sketchup .skp models, will be described. 

1 Download some test data

You can find a lot of 3D Model on Googles 3DWarehouse. For this tutorial we will download three buildings of Barcelona. 

I choosed the following 3:

Today I have to be a littlebit political (even if this is completely against my principles, because I normally think politics is at best a joke, but this is how the system works these days).

 This is a blog post about installing UNR 10.4 (Lucid) on a Asus t91mt convertible Netbook with GMA500 (poulsbo) drivers and full multitouch touchscreen support.

This is basically a summary of several blog posts I read throug for the installation proces, but I found no summarizing HowTo with some simple steps to do this task, so I do this here. 
 
1. Install UNR 10.4
  • Download the UNR distro ISO from http://www.ubuntu.com/netbook/get-ubuntu/download
  • Follow the instructions on that site to create an bootable USB drive from the ISO
  • Plug the USB drive to your t91mt and boot, press the F2 key on to select the USB drive to boot from.
  • Follow the install instructions

2. Install touchscreen with multitouch support
