What about mapping Datsville in four zones? Each zone matching a
quadrant in the (x,z) coordinate system. Within the zones it will be
possible to use positive coordinates.
It could for example be like this:
+ Zone A (x>0,z>0)
+ Zone B (x>0,z<0)
+ Zone C (x<0,z<0)
+ Zone D (x<0,z>0)
Within each zone the coordinates of a plate can be written "Z-I-J",
where Z is the zone identification letter, I = ceil(abs(x)/640) and J =
ceil(abs(y)/640).
If I read the notes at

correctly, the above system means that:
+ the fire station is located at A-1-1,
+ my small parisian shop at D-3-3, and
+ the town hall at D-6-1.
Play well,
Jacob

| (...) Thanks for the response. I know you're right; it's normal behaviour for coordinate systems. But I guess I'm not normal. :) For some reason, I have no problems with the y axis, despite it goes the wrong way. Probably because you always know (...)
