The documentation for ITopologicalOperator.Buffer states that "The buffer distance is in the same units as the source shape that is being buffered". The source shape in my case is a point feature. How do I find out if I'm buffering that point by feet, meters, or inches? The dataset that the point feature is in has a spatial reference as follows:
