What benefits does using sophisticated GCPs bring? Can naturally occurring markers replace them? Today's show is all about understanding the use and importance of sophisticated GCPs and their importance in ensuring quality deliverables. Our question for today, from DeWayne, is about using sophisticated GCPs. DeWayne is observing his co-workers and team rely more on naturally occurring markers to make do with their mapping missions. He would like to know if they are indeed effective and if pilots can get away using naturally occurring markers or stand-in markers such as paints and pinstripes A very valid question and we answer the question by first addressing the need for conducting effective geo-referencing in mapping projects. We then dig deep into the use of sophisticated GCPs and the rules that pilots need to consider while carrying out missions. We then list out all the possible errors that can occur in georeferencing due to poor selection of GCPs and how it can impact final deliverables and follow it
