Accuracy values? #13

Closed spyhunter99 closed 5 years ago

spyhunter99 commented 9 years ago

The documentation for the accuracy field is confusing

In one function it's (function forward)

      //   5 for 1 m, 
      //   4 for 10 m, 
      //   3 for 100 m, 
      //   4 for 1000 m or 
      //   5 for 10000 m

In another function, "accuracy (in meters)"

I'm actually trying to figure out how to use

function encode(utm, accuracy)

That snippet of information is wrong. The greater the number, the bigger the accuracy. Accuracy to the precision of 1000m is therefore 2, not 4.

Good catch. A new maintainer here :-) We'll fix that.

This should be fixed now. Let me know if you have any questions: https://github.com/proj4js/mgrs/blob/master/mgrs.js#L42 image
