Today's question is about drone mapping and modeling. What are some expert tips for creating highly accurate drone maps and models?

Our caller for today, Roy has gotten a big job from a real estate company that involves mapping a large 69-acre piece of land. He is planning on using a Trimble G7X and five GCP's for the job. Will this suffice? What workflow should Roy follow to accurately map a large 69-acre piece of land?

To answer Roy's question, we first explain the basics of drone mapping. You will learn, the different variables that affect drone mapping accuracy. Additionally, we reveal the recommended workflow for mapping large tracts of land. Other topics discussed in today's show include difference between drone mapping and traditional surveying and workflow for creating interactive drone models.

Thanks for the great question, Roy. Fly Safe!
