Populating the z-value with a surface

The z-values for features can be populated using a raster file to interpolate the appropriate values. The Populate Z for selected features tool allows you to specify the raster file from which you want to interpret the z-values.

Remarque :

3D Analyst must be installed to populate z-values using a surface.

Étapes :

1. Start ArcMap.

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.
