Hi Victor, Many many thanks for your help on this matter. I have generated a harvesting plan using contours and buffers in a similar way to the method you proposed. I will however use your method in the future as it appears to be a little more semi-automated when compared to my approach.
A quick question, if I use your method and want to split up each contour such that its size is around 5 ha, would I be able to do this using an 'out-of-the-box' module in sexxtante? Once again, many thanks!
