I noticed a note to myself at my desk this morning. It has 1degree = 111.32 Km. So, 1/1000 of a degree (0.001) would be 111.32 meters, not 1.11 meter.


Yes, but how about if you were standing near one of the poles.  Is that still the case?  ;)

*Hopefully*, you're dealing with projected data in a GeoMason simulation so that the distances between things are more-or-less sane.  That is, the underlying engine assumes co-planar spatial data, which you definitely won't have with lat/lon values; this will particularly have an impact on judging the correct distances between geospatial entities.  

One of these days, alas, it'd be nice to have better support for that, but that's for someone else to investigate.
