I have some nautical charts in .BSB format. GDAL can read bsb and I successfully imported them to qgis. But I can't figure out what is the coordinate system they use.
Does anyone has some experience with .bsb ?

In the FME Readers and Writers Manual we note that the coordinate system for BSB is always what we call LL-WGS84. It seems that EPSG:6326 is the equivalent.
