What: If you use the default settings to display your hillshade, you are likely to see a really pixelly looking image, especially if you zoom in on your map. Why: This is not the smooth display that we really want to see on our map. Since the default for the software is to assume we are dispaying discrete data, such as zoning, land use or soils, the resampling method for the display is not set appropriately for smotth continuous data, such as hillshades and layer (hypsometric) tints. so we need to override the default. How: A smoother looking display for continuous data can be easily achieved by simply setting the display resampling method to Bilinear Interpolation.
