Thanks... Very Informative. In my area my nearest geo marker is a couple miles away from where I need to fly. I'd need an armed guard to protect my base station if I set it up over the marker! Other issue typically is there is a lot of tree cover that grew up over these old markers. OK for land surveyors but not so good for aerial surveying. As a work around I carry a chainsaw. Always be resourceful! Keep up the great videos Barry!
Really interesting! I am based in the UK so hunted around for a similar resource data set. I have found the GeoIndex - British Geological Survey but not clear if there is a relevant data set to overlay for such markers shown in your video in the USA (but in the UK). I'd welcome your thoughts!
I wish I knew. That said, the UK is one of the most mapped places in the world (thanks to the wonderful ordinance survey maps) and so I would be surprised if these didn't exist. Try searching for trig pillar and see what you come up with !

Agreed. A lot of these markers are super old and not in ideal locations. The demo one was on someone's path!
