Extract XY data from polygon

[SimonSchnider]

Does somenone have an idea how to extract xy data from an existing polygon?

I have glacier outline and want to use outline coordinates for an ice thickness interpolation, setting the thickness at the glacier outline to 0. The resolution is not (really) important.

Thanks in advance.

What license level are you using?  If you have ArcInfo, you can use the Feature Vertices to Points tool to convert the vertices of the polygon to points and then the Add XY Coordinates tool to append the XY coordinates to the points.  You only need ArcInfo for the Feature Vertices to Points tool.

The other method is to create two fields in the polygon layer. (type Double) to hold the x and y values.
If the layer projection is different from the xy values you want to get, you can set the dataframe projection to the desired one.
Then open the table and right click on the new X filed. Choose calculate Geometry.
Choose X coordinate of Centroid, and use the coordinate system of the dataframe,
Click ok.
Do the same for the Y field.
