Re: [Repast-interest] A serious bug in MoveByVector

Dear Nick,
Thanks, this explains it - from my observations it seems that 90 degrees points north, 180 points west, 270 points south and 0 points east (so not only rotated to a conventional geographical axis, but anti-clockwise rather than clockwise!).
I would strongly urge you to consider revising this.  Agent-based modellers using geography projection/GIS display working with spatial data will undoubtedly be expecting Geographical coordinates and if they don't check their model well then they won't realise that it is doing something that is not expected.  As a geographer, I wasn't even aware there is such a thing as a 'mathematical axis' with 90 degrees as north!
Thanks for the clarification, and geographers out there may find my conversion in my previous post useful.
Best regards,
Hazel
