While we're at it, what's the consensus for the terminology for the
Cartesian system with origin at z = 0 tangent to ellipsoid, z up, y
north? Choices so far:
local Cartesian
ENU
topocentric
It seems that topocentric is the best, and this doesn't tie you down to
Cartesian coordinates. Transforming to polar gives azimuth-elevation-
distance.
