Actually they are referring to the characteristics of the sampling strategy. This can be described in the context of the procedure/platform/sensor, or in the context of the foi, or simply reflected by the coverage-domain within a result expressed as a coverage. They are none of them wrong. My sense is that common practice in the fluid-earth sciences is the latter - mostly what is being shifted around is a result-with-sampling-strategy-embedded-within (i.e. the grid parameters). That's OK. IMHO the O&M model allows us to understand this better as it provides a language to describe it. ______ Simon.Cox@xxxxxxxx CSIRO Exploration & Mining 26 Dick Perry Avenue, Kensington WA 6151 PO Box 1130, Bentley WA 6102 AUSTRALIA T: +61 (0)8 6436 8639 Cell: +61 (0) 403 302 672 Polycom PVX: 130.116.146.28 <http://www.csiro.au> ABN: 41 687 119 230

Feature of Interest should be an earth realm or a name place from a gazetteer, where we could infer the earth realm. Should not be a geometry, as Ron said.But, my feeling is that when a domain scientists refer to a type of data ( trajectory, station, profile .. ) they are really referring to characteristics of the observing procedure ( in this case .. the constraint behavior of a sensor or platform ) which is confused sometimes with the feature of interest.-Luis
