Scanned Seismic and Sidescan Sections |
JPEG2000 |
An
ongoing effort to scan and convert all of GSC’s
analog marine survey field records ( seismic, sidescan
and sounder ) to digital format., These records
have been scanned at 300 dpi and were converted into JPEG2000 format. Install
the application QCJP2 to
convert these sections into BMP files at reduced scale or to adjust tonal
balance in JP2 files. Files are
located in directories referenced by the
expedition name To view
images, download the free IE/Firefox plugin at : http://www.lizardtech.com/download/dl_options.php?page=plugins |
At the
moment, these are geospatially unregistered images. These files can be converted into rectified SEGY files using RegJP2000 |

Digital Seismic and Sidescan Data |
SGYJP2 |
Compressed
SEGY/JPEG2000 files. Segy files can be encoded in this format using the application
sequence : Navigation
from ED can be inserted using the application : Data can
be viewed and interpreted using : |

ED Offline / MergeNav |
Windows Xp |
This tool
may be used to query GSC’s marine survey data
holdings. It contains all of GSC’s navigation track
data and all of the related PAD data for this cruises.
It may be used as a planning and assessment tool for harvesting geophysical
data in area of interest. This tool
is also used to merge navigation derived from ED into headers of SGYJP2
files. It provides rudimentary layback correction. |
