MinLatitude and MaxLatitude are numbers from -1000 (south pole) to 1000
(north pole).
TileRel is about the relation to a specific other tile; currently only available
for action enablers (see also README.actions) and a select few effects. It is
one of "Same Region" (on or adjacent to the same continent/ocean as the other
tile, depending on range) or "Only Other Region" (only adjacent to tiles of its
own or the other tile's continent/ocean, not a third one; not available at Tile
range).
MaxDistanceSq is about the (squared) distance between two tiles; currently
only available for action enablers (see also README.actions) and a select
few effects.
