measuring area

Miller80

Am i correct in saying that when measuring a rectangular field you multiply the length by width and divide by 4840?

pakalasa

Length (in Meters) by Width (in Meters). Will give you M2 (meter squared).
Divide by 10,000 to get Hectares.

To convert to Acres, multiply by 2.471.

So a field 178m x 203m = 3.61 Hectares or 8.92 Acres.

Or in feet and acres, 43559.66 Ft Squared = 1 Acre

Just on measuring Area is there a free App for measuring fields that are not square, of is there a method of doing it the old fashioned way ? i know you could get a contractor with a gps on his tractor

If you can navigate your way around this site you can get the area of any field even it has 10 corners

Only really works on the pc but I use it all the time. Search for" measuring area with google maps" and follow the link to the daft logic site.. it uses google maps so once you have your areas covered you can measure area and excl rough area.. also does length which is handy for fencing and water pipes...

do you need to register with daft logic for it to work

I use this site. Free too.

If you have an andriod phone, theres an app called "Smartarea"
and "GPS Area Measure" which are free. Great job if you a big awkward shaped field.

Its probably avail for the IPhone aswell

quadboy

that acme planimeter one is good although its showing up as slightly less than what the area aid map says but not by much

I always found www.surveying.org to be the handiest website. Again, based on google maps

quadboy

surveying.org gives you length too but when getting the area you cant click into the shaded area for going odd shaped fields

vincenzolorenzo

In that case what I do is click to add a point and then you can drag that back into the spot you want it

yeah works with a bit of tinkering around
