Hello, I wanted to know if you are in the development of an improvement of the magic tool to recognize the differences between crop and weeds, since flying very low the drone mavic 3M (15m) you can achieve an accuracy of 0. 4cm/px which is totally sufficient for crop and weed detection, it is also interesting to develop also the possibility of marking the planting line, which would help the tool to detect any green that is not in the planting line, if such a tool is being developed, I would like to be a beta test to test and help to correct, because it is what many other programs are offering as a novelty in their platforms.
Thank you for your comment. First let me mention that making the grid very small does not mean the tool will detect better. In fact you should select cells that contain crop + weeds and other cells of crops only.
We will release a faster Magic Tool version in the following days with improvements in green on green cases, even without parking the planting line. Stay tuned 
Thank you Jose!
