I used GlobalMapper for the MP export. cgpsmapper has a bunch of warnings processing the MP file, however they are not fatal. The chart did eventually come out to work correctly on my GPSMAP 62s, however does not have the level of readability as BlueChart. I'm wondering at what part of the conversion process can that be changed. I'm assuming when Global Mapper reads in the file. Ultimately, I'm hoping for a automated solution because manually editing the NOAA charts every year/month is tedious. Especially since maritime charts change very frequently.

Thanks again

I exported a Polish MP format and tried with MapTk. It encounters errors.
