I am try to convert some data from a MaxSea
300b.ptz file into a format I can use. It was easy enough to convert the database to a text file but I am not certain how to convert the listed lat/lon into a useable state. My first thought was they were in radiuse but that does not seem to be the case. Anyone have a clue?
A couple of lines from the file. This should be around Boothbay Maine
