| Jan 11, 2021 at 15:30 | comment | added | TernPloverLab | @Spacedman - The first image is a bunch of green dots (with a standard black outline). The is a point (dot) taken every 5 feet across this crop field so at the zoom level I took the screen shot it looks black. The green dots are just some points that must be positioned to where they actually show through, but they are the same as all the others. I will tried running the buffers on a single 24k point field and it ran for 10 minutes until I killed the program. | |

If it is overlapping markers then you could probably do a small circular buffer at each point and then dissolve to get something like the second image. | |

After connecting the nearest neighbor make it your next focus point and pop the last point from the queue of points. This won't work in all cases but it could give you a first spark? towardsdatascience.com/… | |
