Perfect mark coordinates different!

So I averages 15 coordinates using perfect mark:

N 32° 47.2385', W 97° 6.1159'

I looked them up on google maps and they're perfect.

I submitted my cache and it rounded the coords to

N 32° 42.239 W 097° 06.116

The difference between the two is huge!!!!! Why, and how do I fix this?

Quite a difference between 42' and 47'. Typo?

I assume that the 47 to 42 is a typo, but otherwise, this is a difference of probably less than a couple feet.

I had this whole thing typed out...

Am I missing something here? I always thought that the thousandth's place in the minutes was about 6' per count, so if your measurements were rounded in the 10-thousandths place...

So an error of 3' or so?

assuming you were talking about the rounding at the .0005 area...

And then realized it said 42 vs 47. That doesn't seem like a rounding thing. Typo perhaps?

EDit: Gotta type faster.

Yep, just did the math, assuming you meant 47, this is a difference of only 3.075 feet.

But, since most gps units and Groundspeak only handle up to three decimal places, this means that most gps's will only get within about 6 feet anyway (not taking accuracy issues into account).

Wait, back up. "Perfect Mark" is an iPhone app, right? (I had to look that up.) Are you familiar with the ...um ...reputation that iPhones have for their GPS accuracy?

Many people will plead with you: Do not use an iPhone to hide a cache.

In direct response to the question posed by the OP...

You typo'ed either 47" or 42" in the longitude. Yeah, I would call that a MAGOR difference.

You need to contact the reviewer for the change.

Inform him/her of the misdeed, it will be re-reviewed because of the great distance, primarily to see if it still meets the saturation guidelines.

EDIT TO ADD: Be sure you supply the reviewer with the cache number. If you don't they will contact you for it anyway.

you marked:

N 32° 47.2385', W 97° 6.1159'

you submitted:

N 32° 42.239 W 097° 06.116

Yep, assuming thats not a typo in the forum, if the cache page has 42 and it was intended to be 47, then thats a difference of over 5.7 miles.. a little more than 3 feet

I wonder how you figured that one out, those coords are in the middle of some woods

And many people will tell you the earth is flat and 4000 years old.

Unless the woods is especially gnarly pacing off 150 feet with <5 ft of error isn't much of a problem.

I had to look it up, too. To save others the time: http://itunes.apple.com/us/app/perfect-mark/id327378629?mt=8

Perfect Mark is a tool for more precise GPS location & coordinate capture. You can save coordinates on iPhone, send them in email, copy to iPhone's memory (clipboard) or open them in Google Maps.
