SID vs ODP
We all know that Standard Instrument Departures are there basicly to make it easier on the controller, and Opstacale Departure Procedures are there for opstacle clearance. Alright, then why does a very low traffic place like FMN have SIDs? (why don't they just call them graphical ODPs!) Also, BZN has a graphical ODP and SIDs but they look pretty much the same. And lastly, why are airlines filing this graphical ODP in their flight plan at BZN? I thought ATC didnt have to know about ODPs?
