In reference to your 3:03PM email about loading the Default Background Maps
as Data Source, that is what I thought I did, but nothing loaded.

Julien et al.,

This worked for me with county boundaries (with topographic data consisting of 
the geopotential height of the ocean or ground surface in a 40 km NAM model 
run).

However, once the map boundaries were plotted on the topography, I couldn’t 
control the line widths—they were stuck on the narrowest width (presumably 1 
pt.). Specifying other widths in the “Point Size” text box of the “3D Map - 
Topography” control window (and pressing the Return key) had no effect. (I can 
change the line color, though.)

Also, if I add a color-shaded or color-filled contour plot of topography, then 
the colors compete with the map boundaries also plotted on the topography, so 
that the map boundaries aren’t always visible. (Selecting "View > Bring to the 
Front” in the 3D Map -Topography control window doesn’t do anything in this 
context. Increasing the transparency of the topographic color-fill or 
color-shaded plot helps, but of course makes the topography less visible.

I wouldn’t be surprised if this is something buried in the Vis5D code and isn’t 
accessible to IDV developers.
