Ensuring DEM consistency
The Set Consistent DEMs Symbology tool allows you to set the digital elevation model (DEM) so the DTEDs in your map appear to have the same heights.
- Start ArcMap.
- Load the DEM files you want to use to create contours in ArcMap.
- On the main menu, click Customize > Toolbars > Production Contouring.
Click the Set Consistent DEMs Symbology button on the Production Contouring toolbar.
The Set Consistent DEM Symbology dialog box appears.
Choose the minimum/maximum height option you want to use for your raster layers.
- Set Min/Max to Lowest/Highest—The lowest and highest values of the DEM layer are automatically found, and the visual representation is set accordingly so the layers' heights are all the same.
- Customize—You define the minimum and maximum values for the layer.Note:If you define one and not the other, the value is automatically set.
If you chose Customize in the previous step, do one or both of the following:
To define the minimum value
Check the Min check box and type a value in the Min text box for the minimum height values for the layer.
To define the maximum value
Check the Max check box and type a value in the Max text box for the maximum height of the layer.
- Click OK.
