--show-profiles=1
Sets a flag in tdb file which enables profile calculation in MapSource or
Basecamp based on contour lines.

No, if show-profiles = 1 and DEM data is present, the profile is calculated from the DEM data and *not* from the contour lines

If DEM data (see "Hill Shading (DEM) options") is available the flag changes the status line to show the height when you hover over an area with valid DEM data.

Agree

Maybe add a remark that if show-profiles = 0 and DEM data is present, an elevation profile is always available?

Hi Minko,

thanks for the data. I can confirm now that a profile is shown.
So, I suggest to change the description for the option from
--show-profiles=1
        Sets a flag in tdb file which marks set mapset as having contour
        lines and allows showing profile in MapSource. Default is 0
        which means disabled.
to
--show-profiles=1
        Sets a flag in tdb file which enables profile calculation in MapSource or
        Basecamp based on contour lines.
        If DEM data (see "Hill Shading (DEM) options") is available the flag
        changes the status line to show the height when you hover over an area with
        valid DEM data.

OK?
Gerd
