[pct-l] Halfmile's mileposts and Google Maps

[dennis.phelan at gmail.com]

I know if you have Halfmile maps loaded onto Google Earth, when you go to one of the Halfmile points the google coordinates will be shown at the bottom of the page.  In the field I also have Halfmile points loaded onto my GPS so I get the same two readings when I reach one of the Halfmile points.  I never have seen the two data points listed together in a single file anywhere.

The North350Blades, the PCTA trailcrew for the north 350 miles of the trail use Google Map coordinates to report our work. 
Some of us also use Halfmile's information for length of work done and also to give us PCT trail distances to our access points (roads that cross the PCT).
My question is: 
If I have the Google coordinates is there an easy way to calculate the Halfmile location. 
Presently I just get both readings in the field.
