Global Mapper User's Manual
The Color Intensity setting controls whether displayed pixels are lightened or darkened before being
displayed. It may be useful to lighten or darken raster overlays in order to see overlaying vector data clearly.
The Translucency setting controls to what degree you can see through the overlay to overlays underneat the
overlay. The default setting of Opaque means that you cannot see through the overlay at all. Settings closer to
Transparent make the overlay increasingly more see-through, allowing you to blend overlapping data.
The Blend Mode setting controls how an overlay is blended with underlying overlays, in addition to the
Translucency setting. These settings allow Photoshop-style filters to be applied to overlays, resulting in often
stunning results. What you get from a particular set of overlays from a particular blend mode setting can often
be hard to predict, so rather than try to understand what is technically happening for each blend mode it's best
to just experiment with different ones until you find one that you like. The Hard Light setting seems to work
well with satellite imagery overlaid on DEMs, but the others can be quite useful as well.
The Transparent option allows a particular color to be displayed transparently, making it possible to see
through a layer to the layers underneath. For example, when viewing a DRG on top of a DOQ, making the
white in the DRG transparent makes it possible to see much of the DOQ underneath. Pressing the Set
Transparent Color... button allows the user to select the color to treat as transparent in the selected overlay.
The Resampling option allows you to control how the elevation value for each displayed/export location is
determined based on the values in the file. The following resampling methods are supported:
