I created a project. I went to Tools and saw that April tags need to be at least 35x35 pixels. If I am flying a job with a Phantom 4 RTK at an altitude of 71m AGL that gives me a GSD if 1.95 cm/px If we calculate that out to 35px by 35px that gives us a target size of at LEAST 28"x28". I use the 71m AGL so that according to Bentley I should be getting an accuracy of +/- 0.20' vertical for my meshes. (That is 3x the GSD.) We had planned on printing out about a dozen or so of these to have as permanent targets that we could take from site to site and have quick control points.
Having to print these onto a piece of media that is about 30"x30" makes this process a LOT less desirable. Is there anything we can do to bring that size down some or is 35x35px the minimum?
