Guest reeljustice Posted July 30, 2006 Report Share Posted July 30, 2006 I seem to remember there is a formula to determine acreage if you know the footage of the perimeter. Does anyone know it? and can you provide it? Thank you for your help. Joel Quote Link to comment Share on other sites More sharing options...

Guest reeljustice Posted July 30, 2006 Report Share Posted July 30, 2006 Re: How to determine acreage from perimeter footag I appreciate your response, but, that calculator does length times width. I have an irregularly shaped piece of property which makes it difficult to divide up into retangular tracts. Perhaps there is another calculator there that I didn't see.

Bond Posted July 30, 2006 Report Share Posted July 30, 2006 Re: How to determine acreage from perimeter footag The perimeter alone won't give you the square footage or acreage. So lets say you have a perimeter of 100 feet and you want to find the square footage, it could be a rectangle of 49 x 1 which will give you 49 square feet or it could be a square(25 x 25) which will give you 625 square feet. So you're going to need more information. It has to be a rectangle or rectangles in order for you to measure it. Try to measure it in multiple rectangles and use that calculator and then add them all up. Quote Link to comment Share on other sites More sharing options...
wtnhunt Posted July 30, 2006 Report Share Posted July 30, 2006 Re: How to determine acreage from perimeter footag My plots are mostly all kind of irregularly shaped. I always just guesstimate my plots acreages based on known sizes of the fields they are in. Quote Link to comment Share on other sites More sharing options...
dogdoc Posted July 30, 2006 Report Share Posted July 30, 2006 Re: How to determine acreage from perimeter footag Bond is correct--you must divide the land into small rectangles then add it all up. Here is a website that might help: http://www.leaprealtors.com/acreage_calc.htm Quote Link to comment Share on other sites More sharing options...
Guest reeljustice Posted July 30, 2006 Report Share Posted July 30, 2006 Re: How to determine acreage from perimeter footag Thanks guys, I appreciate your help. If you can't determine acreage by the feet contained in the perimeter, does anyone know how the GPS computes acreage by driving the perimeter. Also, there is an instrument used in tax assessors' office where they trace the outside boundary of a tract of land and determine acreage? I just assumed since those instruments could compute acreage by going around the perimeter of a tract of land that there was a formula to determine acreage from the feet contained in the perimeter. Thanks again. Quote Link to comment Share on other sites More sharing options...
VTbowman Posted July 30, 2006 Report Share Posted July 30, 2006 Re: How to determine acreage from perimeter footag I am no rocket scientist but if you have a known perimeter and can assertain the sq footage contained within, then you simply have to arrange said sq footage into the 2 demension of a rectangle. IE: if you figure out that the total sq footage is say 4000 sq feet. This number would then repersent a circle perimeter if no other factors were known. But you could do a virtual rectangle then by just breaking that into 2000 length and 2000 width and go from there. Or am I way off.

[/ QUOTE ] Most of those calculations are done on a computer. They place the waypoints from a GPS or trace the boundary in a mapping software and create a polygon that they can calculate an area of. Like everyone else said, you'd be best to break it up into rectangles and get a good ballpark figure. Ben Quote Link to comment Share on other sites More sharing options...
ksbowhntr77 Posted July 31, 2006 Report Share Posted July 31, 2006 Re: How to determine acreage from perimeter footag Alright, if you have irregular lengths on all sides do this: take the two widths, add them together and divide by two, then take the two lengths and add them together and divide them by two. Multiply the two averaged numbers and divide by 43,560. The answer will be the acres that are in the parcel. Basically all you're doing is averaging the length and width, it will be very, very close to the actual acreage if you were to survey it.

Guest anderson3 Posted August 3, 2006 Report Share Posted August 3, 2006 Re: How to determine acreage from perimeter footag I always wondered if there was an online calculator where you could enter four GPS waypoints and it would spit out an acreage.
