Can the area value of a geoshape type be used in a calculation for another field?
We need to determine the area of any polygon created and set that value on another field.

Sure can! You can use the area() function in a calculation field for another question. This example shows the area (in square metres) and perimeter (in metres) of a polygon being converted to hectares and kilometres and rounded to 2 decimal places.
Score! Thanks so much for the example!
Hello Brett Stokes
I have multiple GPS points. Can I do manually type with Multiple GPS Points to create a polygon in geoshape? If we can create a polygon let me know how to create it
Hello Thant Zaw Oo,
You can achieve this by putting your geopoint questions within a repeat. Then just use the sum() function in your geoshape question in the calculate column to build the polygon from the points in your repeat. I suggest joining the Early Adopter Community (if you haven't already) where you can find more detailed explanations on this beta functionality. Here is an example of setting up your XLSForm:
Hope this helps,
Thanks Brett, I could manage it and get polygon well. May I know same questions that I would like to know Sq Meter from this polygon for calculation If you don't mind can you please share me. Thanks.
