Seeking Guidance on GCP Marking for Drone Processing in Dronenaksha

Hello , I am new to DroneNaksha processing I have a few questions regarding Ground Control Point marking.
What is the recommended number of GCPs for efficient and accurate processing in Dronenaksha ? how do i ensure optimal results in drone data processing? Are there any specific do’s and don’ts that I should be aware of when working with GCPs for drone data processing. Thank you

There are couple of things I can recommend but not to be considered as a best advice

  1. Have GCPs marked based on overall area something like 4 distinct GPCs for around 1 sqr km
  2. Have GCPs marked on extreme corners
  3. Don’t overlap GCPs
  4. Mark 10 photos per GCP atleast

Hope this helps to some extent .
