Need spreadsheet for land area calculation.

Need spreadsheet for land area calculation.

Need spreadsheet for land area calculation.

(OP)
Is there such a spreadsheet?  Don't need a CAD program or survey program.  More like a math program.  We did area calcs by hand in school....somehow by putting in angles and distances.

Here's a better one, http://www.vbdesign.net/expresso/showthread.php?s=&thre...;
just wish I was a programmer. Barely remember my Fortran 77!  

Can I list my points px and py in a spreadsheet, then have this sub read and calculate the area?  Since my points are generated by angles and distances, I need to list those first to generate the points, which should be easy!

RE: Need spreadsheet for land area calculation.

Get hold of any good land surveying textbook.

Look up some sample hand calculations for balancing a boundary survey and using the x,y (northings and eastings as Surveyors would say) to calculate the enclosed area.  

If circular curves are involved you may need to do some side calculations.

Then, write your own spreadsheet based on an example to which you already know the answer.  This will allow you to check your spreadsheet to make sure it is working correctly.

Once it is, you can use it to calculate any area for which the boundary can be defined.

That's how they taught me to do it when I was in school 43 years ago, but I don't think geometry has changed in several centuries now.

good luck
