Is the reflected color spectrum of olive trees different from vegetation<br>
that would normally be expected outside the orchards?<br>
<br>
If so, I would suggest a training set obtained by visiting a few olive<br>
orchards and recording the geographic coordinates of the center as well as<br>
an average radius (or the sides of a rectangular orchard). The satellite<br>
band values for those location can then be used to classify vegetation and<br>
find other olive orchards.<br>
<br>
Of course, you've probably already done this, and it's been about 30 years<br>
since I last worked with satellite imagery so I'm not current on the<br>
technologies.<br></blockquote><div><br></div><div> Thank you very much for your hint. I should have mentioned that I made tentatives also in this direction.
