ADU 01125: What is the Difference Between Relative and Absolute Accuracy in Mapping?

Today's question is about the difference between relative accuracy and absolute accuracy in drone mapping and modeling. Our caller for today. James is a professional mapper from Australia. James question is about the difference between relative accuracy and absolute accuracy. Do you need both relative accuracy and absolute accuracy for building drone maps and models? To answer this question, we first explain the difference between relative accuracy and absolute accuracy in simple terms. Next, we dive into the nuances of drone mapping and share some little known tips and tricks guaranteed to help you out. You will first learn how to use GCP's for tying together maps of extremely complex areas. Next, we share some creative drone applications that you might not be aware of. You will learn how to use drone maps for interactive modeling, golf course marketing, and site visualization. We also reveal how restaurants can use drone maps to protect their business in these trying times. Thanks for the great question. Fly Safe!
