I'm trying to calculate a polygon area. This is the polygon and the attribute table:
When i open field calculator and use the Geometry--> area$, the area result for ID 1 is (in squere meters) 1809477.67:
but when i use the
Export/Add geometry column tool, two things happen:
- a new layer been created named "added geom info"- why the data isn't created in the polygon attribute table?
- the area result is (in squere meters): 1799292.92 - why i get different results?
When i measure the area in ArcGIS 10.3 - the result was 1799292.92 squere meters.
I also red
and didn't found any suitable answer.
