Help with zone coordinates

[Arley McFarley]

Maybe my note was too long.

Can anyone describe the relationship between actual, in-game LOCs and zone x-y-z coordinates? Especially z-coordinate. It seems the altitude of the character zone-in point is not consistent with the /loc data for that location.

For example:
I zoned from West Freeport to East Freeport and the zone-in point was at the docks and about 30 feet in the air, relatively speaking. The fall for damage for a level 1 equates to instant death.

I used the Admin tool to change the z-coordinate for the zone-in point (I believe it was -24, originally) to a few different values and eventually got to a relatively safe landing with a value of -4800 or so.

This did not match the z value in the /loc command.

Where is 0, 0, 0 location in the actual game zone? 0 value for z-coordinate must be an astronomic altitude if -4800 puts you closer to the ground at that /loc.

Then, again, perhaps I'm just not reading my information clearly.

Does anyone have a response for this inquiry?
Perhaps I should be posting this request for info in the developer or worldbuilder section.

Any help would be appreciated.
