Map transparency is a method used to highlight
trends in your thematic data and make patterns more comprehensible
by varying the level of opacity in map features.
There are several reasons you may want to apply some
transparency to a map:
- Some areas of the map are dense with point features. By
applying some transparency to the features it is possible to
see where they overlap.
- Outlines on polygons might be distracting and pull your
audience's attention away from the main thrust of your map.
By adjusting the opacity of your area boundaries you can
focus more attention to the map topic.
- You want features that have a high value in a thematic
map to stand out more than those with a low value. By making
features with low values more transparent they will fade
more into the background.
By applying some transparency to the
colored dots in this map, it is possible to see the smaller dots
that would otherwise be completely hidden by larger ones such as the
large purple dot in Los Angeles, California. Also, by applying
transparency to the county boundaries it makes the thematic map
easier to see and understand.
