The S-57 ENC is a complicated data structure with many intricacies. Over in the MS Windows world 7Cs provides the tools to create S-57 ENCs and read and display them. Unfortunatley those same tools are not on Mac OS X. So back in 2005 I began the steep learning curve of figuring out the S-57 ENC data structure. After almost two years of working with this format I learned a lot. From that information I have developed a new S-57 rendering engine for MacENC. It is faster and provides much more detail than before. This new rendering engine will make its way in the next release of MacENC which will be released early next week.
