Vector Maps - Kanardia Nesis III User Manual

Nesis III User's Manual
They are drawn in a separate layer. See Figure 92a.
• When raster maps are used, they are drawn next. It is important to
note, that they hide (overwrite) all layers below, in the part, where
raster maps are visible. Figure 92b shows an example, where left part
of the screen is covered with raster map and the rest is vector map. The
figure shows how raster map overwrites all previous layers. It also shows
that both maps blend together pretty good.
• When weather information is available, it is drawn next in a semitrans-
parent way.
• Approach maps are drawn next. They are also drawn in a semitrans-
parent way where the transparency can be adjusted.
• Active navigation details, airplane symbol and other navigational and
operational items are drawn the last.
