> Hold on a minute there. Not that I disagree with coordinates, but I seem to remember that Kent also shows Grid bearings and SURFACE distances. While this in and of itself isn't wrong, you've literally got TWO sets of data that won't jive.
Kris, I take it that you didn't notice that I provided the recipe by which you convert exact grid distances inversed from the grid coordinates to surface distances? Better than simply stating the average Combined Grid Factor for the project, I give an example of how to apply it. A surveyor who can't figure that one out is in much worse trouble than simply being in error by the difference in scale factors. :>
My comment was not really about using coords in a description as a form of call...
I just want an easy, fast way to plot long recorded easements! Plotting was my only concern.
Interesting discussion, though.

Well, the coordinates in that description I posted serve a useful purpose that may not be obvious. If you study the sketches on Sheets 17 and 18 (the first and second pages of the second pdf linked above), you'll see that the sidelines of the easement strip are only monumented at intervals. This was a conscious decision to serve several purposes, not the least of which were:
a) to simplify resurveying the strip (in Texas missing all boundary monuments would need to be located) since the process really amounts to just verifying that the access road pavement and associated uses are within the easement strip, and
b) to make it possible to fairly readily establish any of the lines of the 25 ft. strip if desired.
So the monuments at intervals along the sidelines were chosen to serve as resections points from which a total station set up between them could fix its position and set out any intermediate lines and curves. This is where having the coordinate list, complete with Combined Grid Factor, ready and loaded into the data collector is a huge advantage. The grid coordinates make it possible to readily locate the monuments with a suitable GPS device and then the rest can be easily set out from them.
The whole scheme was chosen with the object of maximizing utility and economy.
