C-MAP File

A file with the .C-MAP extension is a file known as C-map. It belongs to the GIS Files category. This format is associated with Jeppesen Marine, Inc..

The reliable way to open a .C-MAP file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.

We are still gathering the list of programs that open .C-MAP files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
