Examine the DEM Result

Examine the DEM Result

Once DEM extraction is complete, you can examine and/or edit the resulting DEM. The last screen of the Wizard provides two options. Both options load the DEM result to a display group, but one option also opens the DEM Editing Tool so you can edit the DEM.

Load DEM Result to Display loads the processed DEM result into a display group.

Load DEM Result to Display with Editing Tool loads the processed DEM result into a display group and opens the DEM Editing Tool dialog for editing the DEM. This is the recommended selection, since you can use the DEM Editing Tool to fix any bad DEM values in the output DEM. See The DEM Editing Tool for more information about this DEM Extraction tool.

After you have viewed and/or modified your DEM, click Finish to exit the DEM Extraction Wizard. This opens an ENVI prompt asking if you want to save the current state of the DEM Extraction Wizard to use at a later time.

Select Yes to save the DEM Extraction Wizard to an ASCII .txt file.

Select No to continue exiting the Wizard without saving.

Click Cancel to return to Step 9 of 9 of the DEM Extraction Wizard.
