Get your own evince coordinate verification link.
It's simple. Just select the type of verification you want to use, and
click Submit. On the next page, enter the coordinates (and radius if
needed), and you'll be given the code to add to your cache page.
For most situations, you'll want to use Normal Verification. Most
puzzles are solved to an exact set of coordinates. Normal
Verification checks against those coordinates, and only returns a positive
confirmation if it's an exact match. This method is the most secure, as it
makes guessing at the right answer much more difficult. You should select
this method whenever possible.
But there are a few cases, such as when projecting a waypoint, where it's
possible, because of the nature of the calculations, that a
right answer is not necessarily an exact answer. For that,
we have the Horseshoes & Atom Bombs method, for those times when
close is good enough. When using this method, you'll also need to enter a
radius (in feet) from the coordinates. Coordinates within this area will
be considered to be correct. Note that using this method makes it easier
for people to attempt to guess the correct coordinates, so you should only
use this when you really need to. However, regardless of which method you
use, we still apply several anti-guessing techniques to lock-out cheaters.
