It looks like the DNC you are looking at are in Vector Product Format,
so google "gdal vpf" and you will get some links that might help with that.

Hi,
If you have a link to the charts, I could look at it and see the format
and see if they are georeferenced (if coordinates like longitude and
latitudes is included in the image file). They should be. If so, I
would recommend you use a GIS software like QGIS to visualise the maps
and manipulate the map. QGIS has plugins that will permit you to plug
in a GPS and to track the movement for navigation.
QGIS uses the GDAL library to open, save and manipulate maps images
(rasters) and point, line and polygons (vector data) so you get all the
power of GDAL and a user friendly interface.
