Comment (by pramsey):

 Good, don't bother testing M in case we want to change it. As it stands
 the behaviour is hard to describe in terms of KNN (if your coordinates are
 lon/lat then your nearest distance will be heavily affected by the M, if
 your coordinates are in something projected, the nearest distance will be
 more likely to be spatially determined). Maybe it's best to just ignore
 M/T entirely for the KNN op.
