than the absolute elevation. This shader allows you to easily identify things like the portions of the<br />

terrain that face south, or any other direction. The colors to use for each direction are user<br />

configurable on the Shader Options panel.<br />

• If any custom shaders have been created, they will be available as well.<br />

Use the Enable Hill Shading option to view elevation data as shaded relief. With this option off, the map<br />

appears flat, with elevations distinguished by color only. With it on, shadows are generated using the loaded<br />

elevation data along with the remaining settings on this panel.<br />

The Elevation Display Units option allows you to modify the units that elevations will be displayed in on the<br />

status bar as you move the cursor over loaded elevation data.<br />

The Lighting Direction options set the position of the light source (the "sun") for performing hill shading.<br />

Note that cartographic azimuth and altitude are used. This means that 0 azimuth means the sun is to the north,<br />

90 azimuth means the sun is to the east, and so on. An altitude of 90 means that the sun is directly overhead,<br />

while an altitude of 0 means the sun is on the horizon.<br />

Use the Ambient Lighting to brighten up dark looking data sets or dim bright looking data sets.<br />

The Vertical Exaggeration setting is used to control the exaggeration of relief features.<br />

The Hill Shading Shadow Darkness setting is used to control how dark that hill shading is allowed to make<br />

shaded areas. By default, the value of 0 allows shaded areas to go all the way to black. By moving this slider<br />

to the right you can cause shadowing to be capped in high relief areas, thus allowing the use of other controls<br />

to better bring out detail in low-relief areas.<br />

The Hill Shading Highlight from Direct Light setting is used to display a whitened highlight area in terrain<br />

areas that are getting direct sunlight based on the lighting angle selected. The slider controls the amount of<br />

whitening highlight applied to those direct sunlight areas.<br />

To enable the display of water on elevation data sets, check the Show Water On Elevation Data option.<br />

The Water Transparency controls the clarity of displayed water if configured to display water. Clearer water<br />

shows more underlying relief to show through, while opaque water allows none.<br />

The Water Level setting controls the level at which water is displayed. The default is set at an elevation of 0<br />

meters above sea level. Use this to simulate different flood and sea level change scenarios.<br />

The Water Color options allows you to set the color of the water. The default is blue.<br />
