I want to apply transparency to several raster layers' NoData for view analysis. Although there is no value, the view shed result picked up that area as visible part. I am not sure is it because of the color applied?&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P style="background-color: #ffffff; border: 0px; font-size: 14px;"&gt;&amp;nbsp;&lt;/P&gt;&lt;P style="background-color: #ffffff; border: 0px; font-size: 14px;"&gt;I hope to use raster for every view category rather than polygon so I can also apply the elevation at the same time.&amp;nbsp;&lt;/P&gt;&lt;P style="background-color: #ffffff; border: 0px; font-size: 14px;"&gt;&amp;nbsp;&lt;/P&gt;&lt;P style="background-color: #ffffff; border: 0px; font-size: 14px;"&gt;In the image below, the black spots represent parks, and other areas are NoData.
