Is Acreage based of surface area or a Birds Eye view

Hi,

A quick and potentially silly question.

Would a 100 acre hill farm for example, have more farmable surface area than a 100 acre flat farm?

If acreage was based off a satellite Birds Eye view I suppose it would?

Yes it would have more area. Had this very discussion with a department of agriculture person who argued strongly that there was no difference in the area. I asked him if we lifted up the carpet of the room we were sitting in and put a table below it and draped the carpet back over it, would the carpet still touch the walls , discussion ended with no more comments

I used to work on a place with a field called the bank. I reckon it was mapped about 30 acres, but apparently sprayed out at alot more.

I wouldn't know by how much as my balls are not big enough to drive a sprayer on terrain like that!!!
