Hallo,
Preisfrage:
Mit was kann ich eine sogenannte *.sea Datei, (was immer das auch sein mag - es ist auf alle Fälle eine Grafik für mich darin verpackt) ???
Tja, man lernt nie aus - (Es eilt auch noch, richtige Ansprechpartner sind nicht zu erreichen !)
Bin für jeden Tip dankbar…
Gruß und Dank
Daniel
Hi,
ich hab bei http://www.wotsit.org nur folgendes gefunden, und wenns dort nichts gibt…

SeaWiFS Project - LEVEL 0 OUTPUT FILE FORMAT
FRAME FORMATTER (LEVEL 0) OUTPUT FILE FORMAT
Version 1.1
Frederick S. Patt
April 16, 1993
Updated May 1996 - see below
SUMMARY DESCRIPTION:
The SeaWiFS Frame Formatter (FF), developed and maintained by the Data
Capture Facility (DCF), will produce one output file for each data
transmission. This will be either a recorded data file, with GAC and
LAC segments interleaved, output twice per day according to the data
dump schedule; or a real-time LAC file, output up to three times per
day according to the SeaStar/GSFC direct broadcast schedule. Real-time
LAC will be de-crypted by DCF prior to processing by the FF. The FF
output file will be first generated on a local disk and then copied to
a disk file on an SDPS computer where it will be reformatted as
described below.
The file will consist of a 512-byte header followed by a number of data
records. Each record will contain a single minor frame regardless of
source and format. All 10-bit telemetry words will be right-justified
in 16 bits and the 8-bit words will be output as such. The
synchronization words will be stripped off. The records are padded to
an integer number of 512-byte blocks, with a record length of 21
Kbytes.
The FF will output only complete minor frames to the file; frames which
are incomplete due to data dropouts or loss of bit synch will be
rejected and no fill frames will be generated. A count of the number
of lost minor frames will be included in the header file. The FF also
estimates the bit error rate for each frame using the trailing synch
words, and this information will be included in the quality flags at
the beginning of each record.

Update to the SeaWiFS Level 0 Frame Format - September 1997
B. Franz
SeaWifs File Header
The SeaWifs Level-0 file begins with a 512 byte header block. Most of
this header is not used, and can therefore be filled with zeros. In
this update to the format specification, several fields have been
eliminated. Only those fields which are currently used or likely to be
used in future releases of L1agen have been retained.
field size -bytes- type
1 5 000 004 char[5] - characters „CWIF\0“.
These characters are invariant.
2 1 005 005 char- if = 0 then this is a LAC/GAC File,
if = 1 then this is an HRPT File.
3 4 316 319 long - Number of aux and/or sync bits examined for bit error calculation.
4 4 320 323 long - Number of bit errors found in auxsync or framesync fields.
5 4 332 335 time_t- Acquisition start time (AOS) in seconds since Jan 1, 1970 00:00, 4-byte integer.
6 4 336 339 time_t- Acquisition end time (LOS) in seconds since Jan 1, 1970 00:00, 4-byte integer.
