Here's a 5-page paper likely written by Oscar Adams and revised in 1948. No math but several philosophical items including a few sentences on the selection of size of area to be covered by a projection. Hope it's interesting.

I love u . Please if u have more can u post it ?!
Hope it's interesting.
Yes, it was.
Florida SPC Zones:
Lambert, 1 zone
Transverse Mercator, 2 zones
So as a land surveyor in a 2km lenth or even more, I would aply the projection to corectly rappresent the true lengh of features in greater distances , but as a engineer i would avoid cordinates and use just bearings to orientate my instrument?
In this case does the setting out of roads over long lengh by coordinates fly out of the window ?
That's a good question and one that I'm not qualified to answer. In the interest of discussion, though, here are some thoughts.
Consider the snippet below taken from Microsoft Word - Chapter- 5- Traversing Principle (wordpress.com)
Having coordinates for the measured points would make calculating an accuracy measure easier if there was a known point to tie point D to, but no such known point exists. Thus, the positions of B, C, and D rely solely on the measurements and an advantage of coordinates is lost.
On the other hand, if coordinates were assigned to the points and points B and D were intervisible, the distance BD and the angle DAB could be calculated easily and compared to their measured values. Note, though, that the same check could be done without coordinates.
A disadvantage to using coordinates might be that, to a later user of the data, coordinates could impute more certainty into the data than is justified.
It really seems to depend on your requirements and usage.
Again, this is beyond my capabilities, so don't rely heavily on what I write.
