Hi all,
Here's my my issue, for which I could use some perspective: we all are pretty familiar with the FGDC standards for data accuracy, wherein a point location has to be within so many feet of the true location at the given scale. However, how does that translate into accuracy over an area? Would that be dependent on the number of vertices (assume that each point must be within the given distance of the true location)? Or would it pertain to the 95% confidence interval [http://www.fgdc.gov/standards/projects/FGDC-standards-projects/accuracy/part3/chapter3: page 7].
If you have any books or online articles/webpages that would offer clarification, I would be indebted.
Thanks for your help,
HC Gordon
