We have a 80 acre farm that has been in our family for 106 years. There are three tillable fields and the rest is pasture and trees. Two of the three fields are very irregular and would be hard to accurately measure using old school means. Is there a simple GPS device and program that a person could mark the perimeters of a field and get a accurate acreage estimate?? Thanks in advance by this technology illiterate person!!! |
If you don't already have it --- Windows only so far as I know --- download and install FREE Google Earth Pro --- NOT the Google Earth that comes up when looking for an address --- Google Earth Pro actually installs on your system.
Find your farm and zoom WAY IN; you can actually see the rocks and tree roots.
Using the many tools included,draw yourself a big square-cornered rectangle that touches four boundary lines.
Now draw smaller rectangles and RIGHT triangles to fill in all the territory.
Google Earth Pro has a very accurate measuring tool; I have used it to measure barns that I already knew the exact measurements and it will always be within inches = plenty accurate for your needs.
Once you have all your rectangles and triangles, it is simple math to come up with total area in whatever increments suits your fancy.
Remember, flip a triangle over on it's long side to make it a rectangle, figure that rectangle's square footage and divide by two to yield the area of the triangle.
ALWAYS RIGHT TRIANGLES else this won't work.
Simple grade school math.
