“All you survey, or only a part? Or, does the crow fly or walk?”
In land surveying, how is acreage determined when land is hilly rather than flat?
That is, measuring the “lay of the land” land with tapes or chains will give different number of feet than the line-of-sight distance given by modern laser ranging.
How steep does a hill have to be before its sides can be ignored–that is, a cliff-face can’t be regarded as a hillside, surely?
It seems to me that in the old days of rod and chain surveying, if I had wanted to buy a farm I would choose acreage in hilly Missouri rather than flat Kansas.
Seems to me that topographical problems can’t be avoided: A timber cruiser working in the flat woodlands couldn’t use the same timber estimation calculations in the mountainous California forests.
Do geographers use the same land measurement techniques as cartographers?
Come to think of it, do modern laser ranging devices incorporate GPS?
