The question arise from reading the standard "OGC® Sensor Planning Service Interface Standard 2.0 Earth Observation Satellite Tasking Extension", that you can get from http://www.opengeospatial.org/standards/sps (Although, I think it is more general and also applies to kml standard too).
Suppose I receive a Polygon expressed in terms of WGS84 UTM latitude longitude points, how should I interpret that set of points? I mean, how should I build the polygon from the points?:

- Should I use great circle curves to join contiguous points?
- Must this be explicitly specified in the interface?
