Learning Claris FileMaker

FileMaker's documentation of the location functions isn't clear what they mean by "accuracy."

 

Here's what I've figured out so far.

 

This is Part 2 in a multi-part series about using the location functions in FileMaker Go.

Where Am I?What’s Accuracy?

In my last post, I described the basics of using the Location and LocationValues functions in FileMaker Go.

 

Now I want to focus on something that’s been bugging me for a while about these functions: accuracy.

 

GPS is pretty good at pinpointing your location, but there are several likely sources of error to account for, so we can’t realistically expect it to be exactly right — thus the accuracy component of a location.

 

Accuracy is accepted by both the Location and the LocationValues functions as a parameter, and accuracy is returned by both functions as a result.

 

But what exactly does FileMaker mean by “accuracy”?
