Trimming rasters ensures that no part of the raster is above surveyed elevations. To do so, follow these steps:
1. Clip raster to high resolution
|
- From the Toolbox, select Clip Raster from Elevations to open the Clip Raster from Elevations dialog.
- In the Clip Raster from Elevations dialog, specify the Raster to clip and the Elevation raster. Specify if the tool should clip elevations above or below the elevation raster.
- Set the name of the Output raster.
- Run the Clip Raster from Elevations tool.
- Examine the newly created raster.
|
2. Clip raster to Lower resolution
|
- From the Toolbox, select Clip Raster from Elevations to open the Clip Raster from Elevations dialog.
- In the Clip Raster from Elevations dialog, specify the Raster to clip and the Elevation raster. Specify if the tool should clip elevations above or below the elevation raster.
- Set the name of the Output raster.
- Run the Clip Raster from Elevations tool.
- Examine the newly created raster.
