DJI M3M: Managing GSD vs Flight time

Agriculture General Ag Questions/Troubleshooting
1

I am looking for wisdom from those more experienced than me… I started flying RGB+MS at a lower height, and the flight durations increased a LOT.

I was flying to identify Corn Emergence (VE) and need to be pretty low to see much. Much of what I was flying was V1.

My questions:

  1. Is anyone really , truly, interested in emergence? (Does anyone really ever replant?)
  2. How high are people typically flying when collecting RGB+MS?
  3. How often are people typically flying over the same field?

I’m looking forward to the conversation

Hi Mike,

Thank you for your comment and for creating this discussion. For all questions, the answer will be, it depends :smiley:
1- A farmer will replant if the density of plants is very low due to a bad emergency, weather damage, etc. In most cases, plant counting is done between v2 and v4.

2 and 3, will really depend on what you are trying to identify/detect. Please visit Corn & Drones: A Practical Field Guide

Lets wait for other user’s comments :seedling:

Thanks, Jose.

I’ve seen that field guide. It is a very, very good summary. We need one for Soybean, too! (hint, hint)

  1. I guess I am wondering if any farmers really need to study emergence with a drone and would act on what a drone illustrates. In my 30+ years of being around farming I’ve only heard of a single time someone replanted. And the need was obvious. I am curious if people are finding use of a drone useful for emergence…
  2. & 3. Can’t wait to learn from others on these, too!
