Install guide
<clob> default is noclobber, i.e. only regenerate if the seismic has changed
<stride> look-ahead factor for 3D (default 25 traces)
<delta> thinning distance for 3D (default 10 traces)
<linc> line increment for symbol posting (default 100 – ignored for 2D)
<tinc> trace increment for symbol posting (default 100)
<size> approximate image size, in pixels (default 500)
<speed> fast (uses seisLTO) or slow (uses seisLTOexact)
<dir> optional single directory to write to; overrides default system directory.
Note that an output file name need not be specified as the png, ASCII or ZGF files are
located with the following naming convention:
PNG image:
$WOW_DATA_DIR/wow_images/<owproj>/<swproj>/<survey>_<seismic>.png
ASCII file:
$WOW_DATA_DIR/wow_images/<owproj>/<swproj>/<survey>_<seismic>.asc
Shapefile:
$WOW_DATA_DIR/wow_shapes/<owproj>/<swproj>/<survey>_lto.shp
(Each seismic volume produces a single shape within the shapefile.)
ZGF file:
$WOW_DATA_DIR/wow_shapes/<owproj>/<swproj>/<survey>_lto.zgf
(Each seismic volume produces a single picture within the ZGF file.)
Examples:
prompt> seisLTO3D SWDEVKIT devnor png (generates default png pictures)
prompt> seisLTO3D SWDEVKIT "{devnor survey}" png (survey has spaces)
prompt> seisLTO3D SWDEVKIT devnor png clobber 25 10 50 50 800
(overwrite the defaults with new parameters).
Generating Outlines for all Projects
Finally, to generate outlines for all 2D or 3D projects with the default algorithm, the scripts
$OWHOME/WebApps/bin/seisLTO2DAll and seisLTO3DAll will run on the
command line with options as shown below. For 3D, specify the –c flag for clobber
behavior; do not specify it for noclobber behavior.
prompt> seisLTO2DAll -t <traceinc> -x <xsize> -o <override dir>
prompt> seisLTO3DAll –c –f <format: png|asc|zgf|shp>
–s <stride> -d <delta> -l <lineinc> - t <traceinc> -x <xsize>
-a <algorithm:slow|fast> -o <override directory>
The directory override allows all shapefiles to be written to a single location, rather than the
default project system directory.
