LTE: Letters to the Editor
Professional Surveyor Magazine - November 2010
Having spent my entire professional career in land surveying (35 years), I congratulate you on writing one of the most insightful articles on the status of land surveying I have seen in many years.

I have a hard time believing Abraham Lincoln had a part in the surveying of Paducah, Kentucky.
As usual I look for the magazine in my mailbox every month and enjoy its contents.
[I created] an alternative solution to problem #210 as I approached it. Only measure to the hundredth of a foot and second of angle; so, our numbers are a little different.
Precision, accuracy, significant digits should be part of a solution, like restoration from the original survey some 200 years ago. Benjamin Banneker did a good job surveying Washington, D.C. (10 miles x 10 miles). It is what it was, and all our modern capabilities should not change what was done back then.

Why calculate segments when you can just use the sectors?
You have to calculate the sector to get the segment anyway. Stop there and you will have no more complicated calculations. Your introduction of the triangle areas involved in calculating the segments introduces an unnecessary trigonometric function. And, the coordinates ... totally unnecessary.
You have used angles in sexagesimal form; I converted to radians to introduce the concept of sector areas using radians (after all, the Problem Corner is to introduce new methods).
There is usually an alternative solution to every problem and it’s OK to use what you are familiar with.

In October’s People, Products, Places, we misspelled the company name “Leica.” The headline on page 50 should read, “Leica Geosystems Opens Five More Solutions Centers.”
In the same issue’s Editor’s Desk
, we published: “And ironically, this affects those of us who many would consider the ‘best’ surveyors among our peers….” What we intended to publish, prior to a copyediting malfunction, was, “And ironically, this affects those who many of us would consider the ‘best’ surveyors among our peers….” It’s a minor difference in syntax but quite a different meaning.
