I have Navionics charts for use with iNavX. I have seen a couple of symbols used on these that (a) are not on the corresponding NOAA chart(s) and (b) not listed in Chart No 1 (Symbols Abbreviations and Terms).
For example, go to 32d 00.4'N 080d 43.7'W and you will find in this general area on the Navionics US and N. Bahama charts a symbol that looks like a sea bird on a long leg. That is not on the NOAA chart nor is it a NOAA symbol.
Another one I've seen is a circle (I think it was red) with a white horizontal bar in it. It looks sort of like a do not enter street sign, but in some places on the Navionics charts they are spread across a large area. Again they are not a NOAA symbol.
Is there some list of Navionics specific symbols?
Thanks in advance for any help you can give.
