I have a map in ArcMap where I want to calculate the area for each of several polygons inside this map.
So I open the Attribute Table, add a new field called 'Area' and choose 'Calculate Values'.
Dim Output as double
Dim pArea as Iarea
Set pArea = [shape]
Output = pArea.area
and Output in the lower field.
But when I try this, I get a message saying that the calculated value may be too large for the field. The end result is that I get a lot of zeros and only a few smaller values.
What shall I do to calculate the bigger values?
