One post every 12 months… stick to your schedule

With shock I realised that I had left this blog more or less untouched for roughly 12 Months now. Embarassing. I hope that in the future I’ll find the time to publish more often.

Now, what did I do the last year?

Beneath other interesting things: I was in Sydney, Australia, and spoke at the FOSS4G 2009, wrote and published a book about OpenLayers and the OSGeo WebGIS software stack, held the keynote at FOSSGIS 2010 about HTML5 and ECMAScript 5 and have a PostGIS talk together with Nicklas Avén accepted at the next FOSS4G in Barcelona, Spain. All in all I have to say that this was a great year with many interesting phases.

Hopefully I’ll be able to go into detail what I did this last twelve months with some follow-up posts soon.


My presentation submission is accepted: I am going to Sydney, Australia for FOSS4G

Last Monday, on the 20th of July, I got an email from the organisation comitee of the annual FOSS4G conference stating that my submitted talk was accepted.
I am proud to have the opportunity to share my thoughts on “Comparing apples and oranges: Uncovering the mystery of component selection in WebGIS projects”. The talk will mainly deal with uncertainty when faced with technologigal decisions concerning component selection for WebGIS projects.
This years FOSS4G takes place in Sydney, Australia from 20th to 23rd of October. I eagerly anticipate meeting with many of the big players in the Free and OpenSource GIS Community.
After the conference is over, I want to stay for vacation in Australia and explore the eastern coast… staring out of the window to see the cloudy Bonn, I really wish I was there already.

Finally: a cheatsheet for OpenLayers 2.7

The cheatsheet for OpenLayers

The cheatsheet for OpenLayers

Since FOSSGIS 2009 is over, I now have the time to announce version 0.1 of a cheatsheet for OpenLayers (version 2.7).

The cheatsheet was compiled by Dennis – a collegue of mine at terrestris – and me. For now there is only a PDF-version available, but we plan to have the cheatsheet released as HTML as well. The PDF-version should look great when printed out – the HTML version should enable you to copy and paste important parts directly from the cheatsheet into your own OpenLayers application.

As for now we only cover very basic parts of OpenLayers: The Map-object, the Layer-object and the Control-object. All of these have certain common methods and properties listed and should help you to get a very quick grasp of the object in case. Additionally we put in the obvious “Hello-World”-example… in this particular case more or less litarally.

The cheatsheet is not an official part of the OpenLayers project or its documentation but is released under the same free license. Both Dennis and I myself are glad that our company terrestris hosts the document on their site.

This is an early version. There might be wrong information in the cheatsheet. Do not hesitate to contact us and comment on the document. Our adresses should be easy to spot in the pdf-file.
