Hello Jim,
thanks for your fast reply! If I understand you correctly I can only set one number for the cell size, correct? The problem is, that the tree crown radius varies from tree to tree. That�??s why I tried to introduce the ratio between area, perimeter and radius. If I generalize the Raster with only one radius I either get too many or too few trees... Or did I misunderstand your suggestions?
Best regards,
Anne
