12 cze 2007 · We set the Z-Factor parameter based on latitude (angular distance north or south of the equator). The Z-Factor parameter is in many Spatial Analyst and 3D Analyst tools; Hillshade and Slope are the two that I use most. Not setting the Z-Factor correctly makes the hillshades look heavy or leaden.

21 lut 2020 · Lastly the Z Factor parameter is used to scale the height of a surface in Z axis . Changing those parameters will alter the shadow of the terrain surface, therefore you can use those parameters to tweak the output of a hillshading in order to get a better hillshading visualization.
23 mar 2023 · The hillshade can make the layer too dark, so you may need to increase the brightness to combat this. Increasing the brightness can cause some loss of detail, so increase the Contrast to 10 to bring this back. NOTE: I found the values above through trial and error; you are very likely to need different ones for different datasets!
13 maj 2021 · Z-Faktor can be found in the layer styling panel of the raster. Set the layer style to Hillshade. There, you also find other settings as azimut, light height etc:
3 wrz 2024 · Z Factor: The Z factor adjusts the vertical exaggeration. If your data’s elevation units differ from the map units, you may need to modify this value. Generally, a Z factor of 1 is suitable for most datasets. Output Layer: Choose the location and name for your hillshade output file.
10 wrz 2024 · What are the key parameters for generating a hillshade in QGIS? – The key parameters include azimuth (the compass direction of the light source), altitude (the angle of the light source above the horizon), and the Z-factor (a scaling factor for vertical exaggeration to enhance terrain features).
This example generates a hillshade raster that includes shadows. Specific azimuth and altitude angles are set and a z-factor to convert z units in feet to meters.
