I want to calculate the area for each polygon region in my table?
Solution
In MapInfo Pro, simply double left click on any Region/Polygon, Polyline or Point object to see its area, length, and coordinates.
To add the area/length to a column -
- Open the Table and navigate to TABLE>Table>Modify Structure and add an field called Area of type Float.
- Then navigate to TABLE>Update Column.
- Select the Table as both the Table to Update and Table to get value from. Select the Area as the column to update.
- Click the Assist button. Select Area from the Function list and click OK.
- Click OK to update the table.
- Note that functions such as sum and average can be viewed by opening TABLE>Calculate Statistics. This displays the statistics for the current selection.
