 OS provides the opportunity to improve processing speed  Compare IT resources required to maintain software  Unfamiliarity for experienced GIS users may lead to frustration  OS provides building blocks that can be used to build out entire system  OS can run without being “installed”  Software update schedules  Licensing restrictions: What does it mean to be “commercially” friendly?  What is the actual cost?

 Now how did we get to that decision?

Emphasize here that we have scratched the surface – encourage a follow-on full study comparing open source desktop GIS to COTS GIS. This will allow us to provide a better recommendation on what to go “open” on and what should remain commercial.

For example, can you build a model in open source, how do you This isdo anit? Is itongoing as “easy” as COTS? project…
