Setting a raster layer's base heights using a surface in ArcScene

Available with 3D Analyst license.

Follow the steps below to use a surface to define the base heights for raster or image layers displayed inside ArcScene.

1. In the table of contents, right-click the layer and click Properties.
2. Click the Base Heights tab.
3. Click the option Floating on a custom surface.
4. Click the drop-down arrow and click the surface that you want to use for the base heights.
5. Optionally, click Raster Resolution to set the resolution of the base surface.

When you drape a raster over a raster surface, the base surface is resampled to 256 rows by 256 columns to improve performance. You can change the resolution of the base surface by clicking Raster Resolution and setting either the cell size or the number of rows and columns. A smaller number of rows and columns improves performance but reduces the resemblance of the base surface to the original.

6. Click OK.

The raster layer is now drawn in 3D using the surface that you selected to provide the z-values.

Tip:

• As a shortcut, you also can double-click the layer in the table of contents to open the Layer Properties dialog box.
