To export one layer, right-click on the layer in the Control Center and choose Layers | EXPORT - Export Layer(s) to New File...
To export one zoom level, on the KML/KMZ Options window, remove the check next to "Automatically Grid Export of Large Data Sets...(etc.)"
To get transparency, specify the PNG format (as you already know) in combination with these other options.
The easiest way to get a good IMPORT command is to have Global Mapper do it for you as follows:
- Load your data into Global Mapper
- Use the Elevation Options | Alter Elevation Values tab to set the Maximum Valid Elevation and Minimum Valid Elevation
- Save a workspace
- Open the workspace file in a text editor such as Notepad.
- Copy the IMPORT command (you will likely also want the DEFINE_PROJ ... END_DEFINE_PROJ lines also so you will have the correct projection information) to your script file.

The Max and Min functions used in the CALC_ATTR_FORMULA command do not operate on the entire data set. They return a result from the items in the list. For example,
CALC_ATTR_FORMULA NEW_ATTR="newattr_2" FORMULA="Min(existing_1, existing_2, existing_3)"will return the minimum value of the three attributes in the list.
If you are using the COPY_ATTRS command, MULTI_AREA=MIN or MULTI_AREA=MAX would copy the smallest or largest value of the attribute when multiple features intersect the area being copied.
