Math Formula for figureing out acreage

You could also figure it like a trapezoid ( when broken into pieces ), or other polygon.. then get your sf, and then divide that down by the 43560.. etc..

Henro:

My explanation is not very good.

On a slope you will have more surface area than on a flat piece of land. The legal survey is based on everything being flat. EG- a big grid with squares on it layed down on the surface and looked at from the top. Because of this you still have the same legal acrerage but different surface area.

The latitude lines are all parrallel to each other. The longitude lines are not and converge at the poles. They are garthest apart at the equator. Legal surveys take this into account. That is why you see "correction lines " every so far on a survey grid that is laid out on square miles like in western Canada.

Perhaps another example would be to draw a triangle with the base haveing one 90 degree angle. The base is what the legal survey measures. The slope is what land is actually there. If I've just confused you farther let me know and I'll attempt to draw a picture to really confuse all.

Egon's right. I don't know a way to explain it better than to sit down and think about it. Really now, if this was rocket science, does anyone think we'd have so many surveyors? /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif

"I'm plotting things out on my survey and its all just for general knowledge that I'm trying to figure it out." 

You've gotten all of the math solutions I could offer already.

Why don't you just call the surveyor and ask him. Around here it's included on the survey. You could also call your county taxing authority. They certainly know how much land they're taxing.

Good idea.. and it may be online. Here in florida, you can log into your counties website, and enter your tax id/plat info and pull up your tax info for the land.. and it does list acerage.. etc.
