So the situation is roughly 13-15 acres of photographed area, 90% coverage using a grid and the area is for the most part square and virtually no ground features like hills or levees.
How many ground control points is about what you think would be necessary?
A colleague recommends constructing about 50-60 of 2’x2’ and 2’x3’ ground control points and I think we could get by with maybe 10?
Would appreciate any feedback and if this is the wrong place for this post please let me know.
I just don’t think the correction we will get having more than 15 is worth the construction time. Would like to see some work done on this, maybe error versus number of ground control points per acre? Might even be interested in doing that research myself since I’ll be having so many of them.
