Talk:ARCHIVE.FSH

• I found out that the field fsh_wpt_t.timestamp was wrong. This actually is two fields containing the northing and easting exactly like in the track points. Thus, I renamed it to fsh_wpt_t.north and fsh_wpt_t.east.
  The fields lat and lon in fsh_track_meta_t and fsh_track_point_t were renamed to north and east as well, to be more clear about its meaning.

• File header split into the unique file header fsh_file_header_t and a fsh_flob_header_t per FLOB (1MB block). The number of FLOBs is found in the fsh_file_header_t.
  fsh_track_meta_t can contain several track references (and not just 1). The number is found in the newly discovered field fsh_track_meta_t.guid_cnt, the GUIDs are listed behind the meta header.

• FSH block 0x22 is a "group", which is a named set of waypoints. It has a header similar to the route header, but missing two fields (the "a" and "b" fields in fsh_route21_header). It is immediately followed by a list of GUIDs (just as with the 0x21 route), and each of the waypoints is identical to the fsh_wpt structure with the notable exception that is does not include the leading GUID, but it is otherwise identical.

• Found temperature in trackpoints, waypoints, and track meta data. Found a timestamp and an additional comment field in waypoints. Redefined waypoint structures.

• Field fsh_file_header_t.flobs interpreted wrong. Fixed.

• Field fsh_track_meta_t.d observed as 7, ARCHIVE.FSH from C90W MFD

• Field fsh_route21_header_t.a observed as both 0 and 3, ARCHIVE.FSH from C90W MFD

• Added clarification for various fields observed from a C90W.

• Route 21 header contains name AND comment exactly like the waypoint. Thus, the calculation of total length of the header changes. See documentation of strucutre. Rahra (talk) 06:56, 2 April 2016 (UTC)

ARCHIVE.FSH version 2 - Updated version of the file format

Jan 17th 2020

I've done more work on understanding the file format for Raymarine Archive.FSH and made new documents containing all the details, please note there are quite a few new discoveries since the original documentation was put in place. I will upload the files to ensure everyone has access to them. Please find the relevant wiki page Here
