I realize that I can edit the chart in a graphics package but then I
would have to re-digitize the edited chart in the .kap format that the
navigation software can access.

For purposes of the chart list, isn't there a companion file in ascii
text that contains a lot of specifics about the raster image? Lists the
stuff about the projection, calibration, etc.?

If your software is building the chart data base list, it may be getting
the chart names from that ascii file and maybe you can edit the names
there. I sort of doubt that it would be reading the chart name from the
raster images.

I found that Notepad adds some non-printing characters to the file even
if I just load then save. I figured out how to use Groovy Hex Editor and
have inserted the appropriate page #s that the .kap charts are to be
found. It all works OK but thanks for your suggestions.

Some nav. software, such as Oziexplorer, will allow you to overprint
anything at all, using the programme itself.

I just found to my surprise that Notepad will work at least on the chart
I tried but maybe it won't work on a larger chart file.
