The DevSummit is your event, and you won't want to miss it. It's the place to get your voice heard and your hands dirty. Ask questions and get into meaty discussions. When it comes to using spatial technology in your applications, this is your ultimate resource for the year, where you'll learn exactly how to build and deploy critical, cutting-edge solutions in your job.

Are you a mapping or spatial application developer? A software architect interested in ArcGIS? Maybe you don't use ESRI software currently. Maybe you live halfway around the world from the California desert. It doesn't matter. You'll benefit greatly.

Hear what some of your colleagues had to say about the 2009 summit.

"As a developer, it's very important for me to know about emerging trends in GIS as well as the tools best suited to my challenges; the summit is very illuminating in both these areas."

-Matthew Gerbrandt, Senior Database Administrator/Web Programmer, Confederated Tribes of the Umatilla Indian Reservation, Oregon

"You can sit down with ESRI developers and ask pointed questions-questions about our own personal experiences-and if someone didn't know the answer, they were able to find someone who did."

-Charlie Messer, Senior Software Engineer, Osmose Utility Services, New York

"I always get the greatest value in being able to talk to staff directly about my problems and projects. Fifteen minutes of finding the right people is worth days of telephone and e-mail tag."

-Rebecca Strauch, Analyst/Programmer-GIS, Alaska Department of Fish and Game

"I loved the deeper patterns and practices sessions available. It's great to get sessions specifically aimed at intermediate to advanced developers too ... I also thought the user presentations were great-a wonderful idea and with very interesting topics that went beyond the normal presentation subjects."

- Aaron VanWieren, Senior GIS Developer, Energov Solutions, Georgia
