How to Correctly Use Ground Control Points in Drone Surveying and Mapping

🔥Get Your Biggest and Most Common Drone Certificate Questions Answered by claiming our FREE Part 107 Guide NOW! - bit.ly/3iv3CbG
Our caller for today, Mark has a great question about setting up GCP’s. Mark is wondering if he can reuse known ground control points for drone surveying. Because most construction sites already have ground control points, reusing these known points will save considerable time and effort. But, can you do so without compromising on accuracy?

    Just another little comment...the preachiness/information quotient was a little high today.

    Lots of "egoless" self appreciation for about half the video. They didn't even address the title question of the video until halfway through. Good info but tone down the "egoless" ego banter..just my friendly suggestion ☺️ if you are clear and stick to the facts people will get that you know what you are doing and pay more attention when your clear information is put into action and works. Happy New year !

    Orthorectifed just means the distortion was taken out of the image, the image has a constant scale. It is not defined as rectifying your map to the curvature of the earth, lol! Google Earth needs to do that somehow, but that’s not what we’re talking about. In fact, an orthorectified image is planimetric, it is two dimensional. Georectified just means the ortho image is tied to some sort of coordinate system on the planet.

    I appreciate your podcasts and understand your thoughts on membership and success. Your pricing is great for enterprise customers or an established business. For someone without a regular customer base though, it may seem to be a little pricey. Not a complaint, just another datapoint for you.

    Is there any way of getting gcp without expensive receiver? I mean, technology L1/L2 is not witchcraft. Is that any hope that technology would be available for wider range of people?

    Only a third way through the video and I feel like the content people are complaining about in the comments should ACTUALLY be a book. The problem is most people don’t understand how Positivity, Perseverance, and Gratitude is the KEY to success. Anyone in business or wanting to be successful and/or happy in Life needs to understand PERSONAL DEVELOPMENT. These comments below are fueled from the ego and negative. If you have something to say it should still be brought up in respectful way NO MATTER WHAT. 1. POSITIVITY - 24/7 365 2. PERSEVERANCE - 24/7 365 3. GRATITUDE - 24/7 365 4. TREAT OTHERS THE WAY YOU WANT TO BE TREATED - 24/7 365 5. LEARN LEARN LEARN - 24/7 365 **6. Watch your life change “stars align” There is a science to the “Laws of Success and Laws of Nature”. This is the foundation of any kind of “Success”. Let’s get itttt!!!!!! 🚀🚀🚀

    Doesn't make sense to me how different sized targets are going to change your projection error. As long as you can mark the center of the target why does it matter if the rest of the target extends 12" in each direction or 30" in each direction?

    Please do yourself a favour and skip to 8:30min, anything pre that is pointless to the title of the video. I truly love these guys and the podcast but it has been getting out of control of late.

    Expand the video description, they always have the timestamps where you can see where the question is asked. I never listen to whatever they say before the question.
