Hi Folks, I'm looking for a method to convert S-57/ENC NOAA marine charts to Garmin format. I suspect similar functionality would also be useful for pulling this data into OSM format as well. NOAA updates their vector based charts regularly, so it's a good data source now. My research has shown there doesn't exist a utility to do this and I'm considering developing a utility. I'm a software developer and reviewed mkgmap, GDL ogr and OpenCPN, all of which have some of the functionality to put this together. The mkgmap Java source is pretty extensive and well organized, so I'm hoping to start with this as a basis or add to the project. It looks like the an S-57 "reader" would be required to get the data through mkgmap. So a new reader would be created in mkgmap.reader.s57. I'm also noticing a more code for "sea" in sea.optional. Any reason why this requires different algorithm for conversion? I see there are dependencies on Geotools, however unsure why. I'm new at the whole map processor, however am willing to learn. Any pointers are appreciated. Thanks, Nick
