I've interspersed my remarks within your original message. Sorry they're so long, but you seem to have rather thoroughly misunderstood what I was saying.

Ah, but the fact that records "are indispensable in finding the truth of my ancestors" was precisely my point. :-)
As for stories, the only way to learn the details that allow you to tell interesting stories is to search the records. A list of co-ordinates may be useful as footnotes - but I know few people who would find that list worthwhile reading in itself.
As a simple example, Larry mentioned parish boundaries in London. I don't know much about London in specific, but let's say I needed to do research there. I would prefer the information that my ancestor's birth was recorded in the records of such and such a parish - which would then be a fairly simple matter to track down - to bare co-ordinates that left me wondering whether or not they applied to my ancestor _before_ or _after_ a parish boundary shifted. The first would make it simple for me to assemble many of the details of their story. The second would leave me searching.
This example, however, has another dimension. In _either_ case, I would have enough information to locate what I needed, _if_ I understood what I was doing. (I could, after all, just search records for _both_ parishes, or all three, or whatever, in the second example.) But the really important caution comes when a novice sees those co-ordinates, makes the assumption that they refer only to the modern parish, and goes terribly astray. They would never get their ancestor's story right. _That_ is the sort of problem that worries me.

I never questioned the worth of GPS co-ordinates for many purposes. My point was subtly different. We need to remember the worth of _any_ source depends on how it is used. Assuming you located the correct spot where your ancestor built his boat works, the co-ordinates to that _would_ reasonably be a valuable footnote to help you - and anyone else who was interested - relocate that spot with much less effort.
_But_, if another person made an attempt to locate that same spot, thought they got it right, but in fact missed the detail that the river he built on had changed names, and instead listed co-ordinates for a spot miles away, _those_ co-ordinates would be worthless at best - and actively harmful to any researcher who took them at face value.
_Or_, even if you pinpointed the correct spot, if you recorded it in such a way that a reader might misunderstand (no matter _how_ accurate the data is, there is _always_ a way to make a mess of it :-) then that record would also be problematic. Those were my points, that despite the undoubted value of GPS co-ordinates - or any other reliable map co-ordinates - for certain purposes, we need to remember that they are subject to all the failings of their human recorders. If you misread a number on your GPS unit, and write or type it incorrectly, the co-ordinate is no longer accurate. If the unit is damaged and the readout offers incorrect data (I don't know the detailed technical issues - but _any_ readout can, at least theoretically, display garbled output), even if you write what it says correctly, you will have useless information. And so on...

The information you record may well be of use to yourself or others - but, like any other "first hand experience" recorded years after the original event, the co-ordinates you record are, in the end, no better than the memories of the men who pointed out those spots to you. One man might remember every site perfectly. Another might be completely mixed up. Without corroborating evidence, you have no way of knowing which is the case. But the accuracy of those co-ordinates is, in absolute fact, no better than the accuracy of the men who indicated the position from which you recorded them. The numbers you have are not a true indication of 'the spot where such and such a structure stood' - they are, within the limits of their technical accuracy, an indication of 'the spot where so-and-so remembers such and such a structure standing years ago'. There is a very important difference between those statements, and we all need to remember that.

But this was precisely my point... ;-) You've just restated it in a different way, citing an authority in the field to back me up. :-D

All true. But my point was that GPS data is no more inherently reliable than any other evidence. If we allow ourselves to be overwhelmed by its "permanence", or seduced by its "accuracy", we will forget it is only as good as the skills of the person making use of the device.

Neither did I. I have no problem with any program including whatever data some of its users may find helpful. If I find that program crams in too many items that I don't find useful, I'll just seek another option.

If they were otherwise equal, I agree. If not, it would depend on what other differences existed, _and why_. But even if I took the one with the digital locations, I'd _still_ want to know more about how that information was arrived at before I relied too heavily on it.

We should all use any and every tool we can find a use for. I said nothing to suggest otherwise. My remarks were a reminder that it is important, no matter what tools we like to use, to remember the ways in which such tools can lead us astray. As one example, some suggested noting the "corners" of a particular boundary. This approach, of course, only makes sense if the boundary has a shape which lends itself to being mapped in this way. Perhaps you could work out an approach which would let you 'outline' a seriously irregular boundary. Perhaps your approach would even work well. _But_, unless I understood what you'd done, and why, it would be of little use to me.
