What do you mean by "map" variables?
Is this another term for coordinate arrays?
Yes, If you look at the underlying DAP, you will
see that coordinate arrays are represented by a Grid
construct which has a "maps" section.
You can see this by looking at, for example:
http://test.opendap.org/opendap/data/nc/123.nc.dds
You do have an alternative.
If you have compiled netcdf using --enable-netcdf4, then you can
do an ncdump -k3 and it will present the DAP data in netcdf-4 format,
and in that format, everything is visible.
