Having trouble with maps
I downloaded SeaClear and MapCal. I also downloaded some maps of the Great Lakes from the noaa site. the file was a zip file that I unziped into a folder I put the file into Charts in SeaClear. One of the files was us3m179m.000 the biggest file. The others were just notepad files.
MapCal will not find this file and the file extension is not supported by any other program. Am I down loading the wrong file? I am downloading raster charts.
