This seems like a bit of a dilemma, & is most unfortunate.
Perhaps we need to subsidise Bob for the quantity to be consumed while he sorts this one out.LOL.
I would think that a large number of BOGers would probably have their own GPS, and if not, hand held types can be purchased reasonably these days.
I suggest we use the Degrees Minutes & Seconds for locations, as with a little practice the location can be determined from the Degrees & Minutes shown on most quality maps, including the Hemma maps, by either scaling or approximation of the proportion of the Minutes or Seconds required.
For those not familiar, the earth being circular comprises 360 degrees. Degrees are broken down to smaller and smaller portions to give greater accuracy to a location, there are 60 minutes in a degree, and 60 seconds in a minute. Minutes can then be further broken down if required by decimalising the proportion of the minute.
Another detailed method could be to use Eastings & Northings as found on Topographical maps, as this directly equates to Meters across the topography (land surface), but the downside of that is that not all GPS's give locations in Eastings & Northings,where I believe they will all resolve to Degrees Minutes & Seconds.
I look forward with interest to the resolution arrived at by more knowledgeable members than I.
Good luck with this one Bob.
