Passing this information around.  I have an idea for 2 to 3 presentatyions myself that I will be submitting.

Anyway, starting today and going until June 29 FOSS4G is accepting presentation submissions.  Presentations are 25 minutes long with 5 minutes for questions and answers.

What makes a good presentation:

• Case Studies: Relate the experiences of you and your organization using open source geospatial. Where do things work well? Poorly? What problems did you solve, and at what cost? What do you recommend for others? Why?
• Benchmarks: Comparisons between pieces of geospatial software. How do features compare? Speed? Ease of use? What do you recommend for others?
• Visualization: Tell about your tips and tricks for effective visualization. How do you present information in a compelling way? 3D? Cartographic tricks? Labelling and naming ideas? Graphs and hybrid map/data combinations?
• Development: What are the new developments in your open source geospatial software product? How does it work, how do people use it, what are the technical issues you are running into?
• Hacks and Mashing: Have you put together something novel or cool this year? What did you stick together, how did it work, show us your gizmo!
• Collaboration: What techniques are you using to improve collaboration between organizations and between individuals. Public geodata, collaborative data collection, data sharing, open standards, de facto standards, and more!
