I worked up a demo spreadsheet that shows how you can label anything with a simple
<b>12 character code</b> (for instance hydrants, or even mail/packages) and have that code encapsulate 6 decimal accuracy geo coding (about 1 meter accuracy). The code is designed to be compact and easy to speak. Case is not important and the letters O, I,
L, and Z are not used because of frequent confusion with numbers (0,1,2). <br>
<br>
The spreadsheet both encodes and decodes. Unambiguous, universal format works worldwide down to a meter.
<br>
<br>
You can get the file named <b>encodelatlon.xls</b> from this directory:<br>
<a href="http://clbcm.com/shrug/">http://clbcm.com/shrug/</a><br>
<br>
There are no macros (or VBA code) in the spreadsheet but you will likely have to "allow editing" if you want to play around with it.
