in a couple of words, yes, very much so. It's not extraneous in any sense, and
I don't understand how you think it involves "taking the extra time". The
degree of precision is of course going to match the same level you employ.
Coordinates can be as precise, or as approximate as you care to make them. Just
allows a point of reference that translates digitally and manually across
multiple tools, including but not limited to maps. Have a "general location"
than use "general coordinates."
But I think if you used mapping to the degree I do, then you would appreciate
the value. Location, even a "general location" in most cases is critical
information, with our without coordinates. Using a reference set of numbers
simply allows you to do more with that location information. Do you do any
family "history" type research?
But even using the reasons that you listed as to why you think location of a
piece of land is important, so you do as I do, use historic maps and records to
identify those items. Often that means going to historical overlays or later
maps that do show latitude and longitude, or approximating (or precisely
finding) location on an equivalent modern map. Once I do that I simply mark
down the coordinates for anything that I "located" by those methods. Then I
can calculate distances etc in various ways. Finding coordinates is not a
difficult, time consuming process. And of course the researcher defines how
precise or general a level those coordinates are being employed at. Useful to
mark even an approximate location (as long as that's made clear).
I don't know why you think it takes extra time? I take it you've never used
coordinates or you wouldn't come to that conclusion. It's a "time saver". It
marks that "USEFUL information" covered by historic maps allowing it to then be
used in a digital environment across maps, employing some amazing tools. Think
of it as a geographic file reference number that carries more information and
can be input into future references and overlays.
But I don't think this is for you Michael, though I think at some point as more
and more digitized mapping tools emerge you'll take another look at it.

I use historic maps in nearly every project. But these historic maps do not
have latitude/longitude on them usually. I also use land records in nearly
every project, which allows me to place the land on the maps (at least in a
general sense). My point is that discovering the general location (especially
when dealing with a 200-acre farm) is an important step, but pinpointing the
exact longitude/latitude seems like an extraneous step that does not add
anything to the research.
I look at it this way – location of a piece of land is important for the
- records jurisdiction
- relation to topographical landmarks
- distance to county courthouses
- distance to nearest town
- location of nearest church
- identities of neighbors
- identifying possible migration routes (through relation to bodies of water,
historic trails, etc)
- (and of course other more creative uses I am sure)
All of these tasks, however, can be completed using historic records and
historic maps, including identifying topographical landmarks, etc. But how
does taking the extra time and effort to pinpoint a precise latitude/longitude
provide additional USEFUL information, not covered by the historic

sorry, forgot to change the subject in that last one.
Good point John, and GPS coordinates mean much the same thing (I just like to
remind people that this isn't based on something new!)
Michael, got to thinking here. How important is mapping and the use of maps to
you in your research? I barely move without referring to a map when I
working on a file. More likely multiple maps. If your answer is "pretty
important" than the use of coordinates is simply going to be a good tool to
have on hand. If you never work with maps, then I can see your point. But I
don't see how I could do effective research without referencing things to a
location on a map of some sort
