(IVS) Fledermaus software suite was used to drape the
sidescan-sonar data on the bathymetric surface. By adding height
information (depth) to the backscatter data, the imagery can be
viewed in three dimensions; greatly improving data interpretation.
The Fledermaus software suite also enables the user to 'fly through'
the study area, presenting unique perspectives, and again, improving
data interpretation. IVS
produces a free viewer, iView3D, that will read files
generated by the Fledermaus software suite. Two Fledermaus scientific
data (sd) files and one scene file have
been included on this DVD-ROM. These data can be viewed through the
IVS free program, iView3D. The user is encouraged to download
iView3D in order to view the geophysical data acquired
in the Puerto Rico Trench, in a three-dimensional perspective.
Download Information:
- Go to the IVS Website
- Go to Products
- Click on iView3D
This will take the User to the iView3D Home
Page. The User will find a program description and detailed
downloading instructions. It is highly recommended that the
User download iView3D in order to view the
sidescan-sonar and bathymetric data in three dimensions and
'fly-through' the study area. The HELP within
iView3D gives detailed operating instructions.
Fledermaus Scientific Data (sd) and Scene Files:
The following files are stored within the ivs
directory and can be viewed within iView3D. See
iView3D HELP for detailed instructions on
loading and manipulating data files. The files may be
downloaded by copying the files from the data\ivs directory or
by downloading the iview3d_data.zip
file which contains the three files in *.zip format . The
User will need the WinZip
program or a compatible program in order to extract the files
from the WinZip archive
