This question is hard to explain so if you have a possible answer I would love to hear it.
I work in the precision agriculture business which heavily relies on NDVI calculations but need to create like zones of crop health for field surveyors and field management purposes. The end users for maps I create are not GIS savvy so presentation is everything. Raster Classification, zonal fills, and reclassification's are not what I want because they are vague and distort the data. On the attached map there are geo-coordinate points over areas with possible health strains and areas that appear to be very healthy.
How do I create zone lines, almost like contour lines, to batch similar points into like areas?
For example, in the Northwest portion of the map, the three points are over similar areas. How do I create a boundary lines showing different zones?
I'm looking for 5 areas:
separated by contour like lines creating zones. I don't want to disrupt are high resolution photography.
