I was running a buffer on a line (1/8 mile buffer). When I went to check the distance to ensure it was correct, it was off by several units. I tried inputting it as .125 miles, as 201 meters and it was incorrect. Am I missing something? I tried measuring from edge to edge, and edge to center point, and both were off. I know the answer is probably simple, but I am stumped.
Solved! Go to Solution.
There's a bunch of information missing here:
There are many potential causes, but the most common is use of a coordinate system for which
distance is undefined, like Web Mercator.

Thanks for the reply Vince.
and from center to edge i get .19 miles.
Measurements in Web Mercator aren't really in meters. The poles are infinitely far from the Equator, so distance accuracy is wrong to start (sphere), and gets worse as latitude magnitude increases (at roughly tan(latitude)). Never measure ANYTHING in Web Mercator, because it can't give a correct answer. If you're working in MD State Plane, keep on using MD State Plane to get accurate distances.
