Would be very helpful if point sampling tool (and the others?) would report where they are getting the data from rather than just giving a column of numbers. So for example they would give the lat long or other coordinate value then the value 228 etc. when I've done tests with datasets containing a few thousand numbers the output sequence is the same as the input sequence (as it should be) but without the coordinates its just a matter of hoping?
