Simple sim scanner

I need to make a scanner to give me owners names on a particular sim, (my estate) I know ther are scanners out ther that do it, but none are opensource, I would like to make one myself for possible use in future projects. I thnk I have found the proper function to implement this( llGetLandOwnerAt )

Now I need to figure out if the next course would be to use a global coordinate or a regional coordinate, and how to actually do the scan.

Any hints and clues would help out alot

You need to use LlGetParcelPrimOwners, passing the current position.
It gives you back a list of the top 100 builders on the sim

Does that work ok for group owned land?
