ATC,

You are corerct that the surface area of the curtain is still the same, however its measurements change. When drawn over the window, the curtain takes up say, 6ft wide and 6ft tall. When opened, the same surface area is condensed into 3ft wide and 6ft tall. The question to your surveyor wwould be how they are measured. If it is over a flat plane, than the undualting surface acres would be assumed to be greater than the flat plan. Thisnk about measuring a house on a stepp mountain side. I have measured homes on mountains that at the front of the home, the wall is at grade. By the time you get the 30-40 ft back to the rear, you have dropped two complete levels of the home, some 20 feet. This distance, when measured at an angle, is larger that the actual distance from front to rear.

The original surveys of township and range which covers most of the nation west of the Mississippi were surveyed using the stars as references corrected to sea level. All original surveys are based upon elevation corrected data, even when flawed, incorrect, or deliberately fraudulent (that happened a lot as surveyors were paid by the acre, often a few cents per acre.) Slopes will have to approach or exceed 45 degrees to seriously affect the surface area, and generally, you will likely find such steep slopes do not produce as much crop as level ground.

A township, in reality, is narrower at the north (top) and wider at the south bottom. This is to account for the curvature of the earth. The further north you go the narrower the township. Since footages do not narrow, acres do not narrow, there is more acres in a standard township in S. New Mexico than in a standard township in N. Montana.

Actually it is every three townships and ranges within each state or with a specific area, that they make the adjustment for the curvature of the earth. Several states have more than one base and meridian. So eighteen miles south or north of the baseline and eighteen miles east or west of the meridian will be an adjustment at the north and west of Sections 1 through 8, 18, 19, 30 and 31--they may be shorter or they may be longer than the standard distances. And then there are the sections with natural barriers like rivers, as well as mining claims. Besides anytime you see a dimension of 1,320' for example, you automatically know it is wrong. The correct dimension might be 1,319.9 or 1,320.1 but never 1,320. And then when you get to Texas where they still use the old Spanish sytem from three hundred years ago insteaf o sections, townships and ranges, it really gets confusing. But everything east of the Miss would even be more confusing to a westerner like me--how DO you find that white oak tree that was cut down 350 years ago???

By the way NASCAR fans, when watching the race Sunday look for all the people sitting on the rocks on the hill to the south overlooking the track. That is the junction of the Gila and Salt River Base and Meridian, the center of Arizona. Everything in the state is in referance to that point.
