In my years at the University of Washington, my greatest accomplishment (along with Eric Darst) was the envisioning, design and implementation of GeoSIMS–the Geographic Space Information Management System.
This online application utilizes a multi-campus set of georeferenced floorplans to enable the tracking of room information. The implementation was a challenge–a lot of different people and departments had to be brought together to make it work. Some groups were indifferent. Some were resistant. Ultimately it all came together, and the UW has a system of space tracking that is streamlined and automated.
For those of you interested in a bit more detail on the background of the program and its uses, you can download my presentation to the University for the GeoSIMS rollout (warning–10 mb Powerpoint file).
