Calculate center's coordinates of polygon in MapInfo?

[Nguyen Leanh]

How can i calculate coordinates of center point within polygon in MapInfo.

The long way:

Create new X and Y columns for your polygon table (Table>Maintenance>Table Structure)

Then update the new columns with the centroid coordinates:

- Table>Update Column

- Select your polygon table and then the X column you previously created.

- Set "Get Value From Table" to your polygon table

- Set "Value" to "centroidx(obj)" (without the quotes)

- Press OK

- Repeat with the Y column ensuring you also change the centroidX(obj) to centroidY(obj)

The short way:

- Go to: Tools>Tool Manager

- Enable and then run the "Coordinate Extractor" Tool

Hope that helps
