Ruckus SPoT API - location data - what are units of length and coordinate system zero point?

[chee_how_lim]

We are working on the "locations" API integraion and I can not find the information about x/y coordinate system used by Ruckus API. 

For example, Aruba has zero point in the top left corner of the floor map. What is the zero point for Ruckus? 

Another question is what units of length does Ruckis use (meter of feet)?

Units are in venue units and can be queried via API if you get venue data via API

I don't see the venue unit in API queried or in configuration of the venue. Could you point out more about this.

Thank you very much.
