Reading random GPS coordinates in an essay without a map in a has high precision but terrible understanding. While it's highly accurate, it's almost useless to the typical reader who would have difficulty knowing that the GPS coordinate is within Colorado. GPS coordinates are for maps not essays.

I agree. The context of your essay would make clear both whether you need that much precision and what format to use for the precision.

Three miles east of the center of South Carolina is almost accurate enough? Who knows, not accurate enough for NASA and accurate enough for giving coworkers the idea of where your farmland is located.
