@satra `15:15 23 Sep 2013` [commenting on seeAlso: "cartesian spatial coordinate datum"]
this refers to a spatial coordinate as opposed to an arbitrary coordinate in N-dimensional space where the dimensions could be space or time or other things such as channels in an MRI setting.

Could use NCI [link](http://ncicb.nci.nih.gov/xml/owl/EVS/Thesaurus.owl#C44465):
"A number or other designation that identifies a position relative to an axis or grid."
