1r CONTENTS 1. Initializing the data processing environment 2. How to use the
menus or doc files ######################################################################## 1. Initializing the data
processing environment In order to access data processin
g directories and scripts, you must first configure your terminal by entering
the name of the survey. Cruise names can be found in the file $ENV/.aliases For example: jus4 This command is an alias
that
execute the command source $ENV/japanus4.env

which defines all the directory settings, scripts, and aliases that you'll need to
process data from this survey. ######################################################################## 2. How to
use the menus or doc files What's to learn? The doc

files are arranged in the order they need to be accessed, so data processing is as
simple as pulling open the top menu, doing what it tells you to do, and moving down to the next menu. If you don't have acce
ss to the
menu window system, use the correspon
ding doc file to access the data processing steps. SUBJECT

Operations Log Survey rs9401r See OPSLOG for rs9401 for original info. The rs9401r p
roject involves complete reprocessing of the
entire data set, funded by Seabed Mapping New Zealand. Client: Seabed Mapping New Zealand Purpose: Reprocessing for
commercial mapping product for SMNZ PI: Bruce Appelgate HMRG Personnel: Data Processors:
Paul Johnson



Doug White SMNZ Personnel: James Clarke, SMNZ Managing Director
------------------------------------------------------------------------

Approach: 1. Look at shipboard and previously
-
reprocessed bathymetry to as
sess its suitability as a product.
Conclusion: shipboard data was pretty good, reprocessed data less good, but neither as good as test plots of data reprocess
ed from
scratch using present software tools. 2. Go back to raw data and develop new AA tables

and attributes files for bathymetry processing.
3. Regenerate sidescan data and use new ssjob scheme for ss image processing. 4. Create new series of 1:100,000 charts that
can
be incorporated into HMRG's new data archive format and presented on the we
b. 5. Create charts for viewing as means for quality
control. 6. Provide grids of bathymetry and sidescan to SMNZ as final product. in order to apply new processing techni Clie

MR1 Data Processing Scripts Survey rs9401r CONTENTS 1. Location 2. ISO

9003 format
#######
################################################################### 1. Locations of scripts A complete scripts
directory should be created for each survey. Usually a new scripts directory is created by copying the contents of the previ
ous survey's
script
s directory. The scripts directory is located beneath $CRUISE. To get there, you need to initialize your environmental vari
ables
like so ew9606 and then type the magic word thusly: scripts and there ya go. In this case (at HMRG), you go to

/home/kaulu5h/hmrg_dar/ew9606/scripts ALL the scripts that you use to do ANYTHING to ANY data from this cruise, EVER, go her
e.
########################################################################## 2. ISO
-
9003 format It is decreed that all
scripts

will be internally documented at a level to pass the Appelgate test. This test is easily performed: give the script to Bruce
, and if
he can figure it out you pass. At a minimum, all scripts should include: 1. a header that describes what the script doe
s 2. a list of
command
-
line arguements 3. a copyright 4. an example of how to invoke the script 5. a list of all other scripts and programs called
within the script 6. an automatic help function 7. enough internal description of what's going on so as not t
o confuse Bruce Here's an
example: #backup_sschart odd_even tape_device # : :.........../dev/rmt/0n or /dev/rmt/1n #

Backup Schedule for Shipboard Computers Survey rs9401r 1. Philosophy 2. Cookbook
#################
###################################################### 1. Philosophy DAILY BACKUPS Once
processing gets going, backups should be run daily. Use two sets of tapes, with one set used on odd days and the other set o
n even
days. FINAL BACKUPS After shipboar
d data acquisition/processing is pau, make two complete sets of backup tapes so that the final
shipboard data are all backed up. PROCEDURE Backups are written from scripts that use the tar command. For fastest transfer
to
tape, write the tapes on the same

machine where the data reside. In the cookbook below, the preferred machine is indicated. As each
backup tape is written, the contents of the tape are listed in log files in the $ARCHIVE directory. Log files are automatical
ly created by
the backup scrip
t, and use the following file name convention: cruisename.year.julian_day.backup_type.tapenumber For example:
ODD days:





EVEN days: backup_misc 1 /dev/rmt/0n


backup_misc 2 /dev/rmt/0n
creates:





creates: $ARCHIVE/japa
nus.98.224.misc.1


japanus.98.224.misc.2 ALWAYS
INSPECT THE LOG FILE FROM EACH BACKUP TO MAKE SURE THERE WERE NO TAPE ERRORS.
############################################################################ 2. COOKBOOK For fastest transfer to
tape, exec
ute the backup scripts on the same machine where the data reside. You can issue the backup commands from any working
directory on that machine

the scripts know where to find the data and where to write the log files. Usually done in this order, here

directory
like so: more $ARCHIVE/japanus.98.299.btyxyz.2 If you see messages that look like this: tar: /
dev/rmt/0n: I/O error or any other
kind of error message, try re
-
running the backup job. If that fails, try using a new tape. If that fails, ...you get the picture.

Raw MR1 Data Handling Survey rs9401r Reprocessing, September 1999 CONTENTS 1. Sucking ra
w data off Doug's CDs
###################################################################### 1. Sucking raw data off Doug's CDs Doug
has made CDs of raw MR1 data that are very useful for reprocessing. Some CDs have nice labels made by Dianna. Lets use
them.
Load a CD into the reader on the computer you're using. Then, copy the raw MR1 files into the $RAW directory. For example,
> cd
/cdrom/rs9401_0016/RS9401_0016 > ls FILE_INFO MR19402001.00 MR19402004.00 MR19402007.00 MR19402010.00

Bathymetry generation in BTYP Survey rs9401r Reprocessing, Sep
tember 1999 We needed to regenerate sidescan and bathymetry
for all files. The way we did this was to run a batch file that created .btyp files that contained both bathymetry and side
scan. We will
use the sidescan in these files as a guide for trimmi
ng the bathymetry in btyp. After that, we will strip the sidescan from the bathymetry
files. ############################################################################ Parameters and tables... AA

Navigation Data Processing Information Survey rs9401r Reprocessing September 1999
############################################################################## Navigation is taken from the one
-
minute shipboard GPS, and is
stored in $NAV/rs9401.nav The nav is broken into two segments reflecting the two MR1 tows, stored in
$NAV/segments


Plotting ship navigation Survey rs9401r Ship's navigation can be quickly plotted using the script nplot (or its variants) or

the script
ke
y_maker. CONTENTS 1. General notes 2. Location maps with chart boxes 3. Page size nav charts, for each official chart
###################################################################### 1. General notes The nav plotting routines
require a nav fix at
the hour in order to properly annotate the nav times. For large
-
area plots, you can use widely
-
spaced nav data to
speed up plotting and optimize the size of your PostScript output file. Try decimating to 10 minute intervals. The script np
lot (or its
vari
ants specific to each survey) requires the files $PARMS/chart/boxes and $PARMS/chart/chart.labels to annotate each survey box
.
These files are set up in $DOC/chart_box.doc. The nplot script looks for navigation in the directory $NAV/segments, with the

nav

for
each MR1 tow named survey.tow##.nav. ###################################################################### 2.

LE
############################################################################## 1. How this file is used
The values
in this file are used to correct towfish compass values to eliminate the influence of the Earth's magnetic field, which chang
es through
time around the world. The data are incorporated into the bathymetry and sidescan processing in different wa
ys: BATHYMETRY uses
corrections on a file
-
by
-
file basis, and requires that the file name be listed in the first column below. Only include bathymetry files that
you want to grid (ie, don't include turns or pieces of data that you don't want plotted
--

t
his is how we kept unwanted bathy data out of
the charts). To see how the magnetic corrections are incorporated, see the doc file $DOC/bty_chart/MR1_to_xyzw.doc. SIDESCA
N
uses corrections on a chart
-
by
-
chart basis, and requires the prefix of the chart na
me in the first column. The declinations are called in
the gridding loop in the doc file $DOC/ss_chart/ss_grid.doc EXAMPLE of how to list the data. Note that negative values req
uire the
minus signs for both degrees and minutes:

ing GEOMAG In order to correctly navigate the towfish, the magnetic compass data from the fish needs to be corrected to
account for variation in the Earth's magnetic field. Magnetic declination changes from place to place, and through time. Co
rrections
to
towfish heading are determined using scripts that incorporate the NGDC program GEOMAG. The corrections need to be added to t
he
doc file $DOC/nav/mag_corr.doc in order to be implimented by HMRG processing scripts. Here's how to use the scripts: Calcul
ate the
(lon,lat) positions of the centers of each chart. This step requires the file $PARMS/chart/boxes, which contains the bounds f
or each
chart:

\
cp $PARMS/chart/JU:03/JU:03.boxes $PARMS/chart/boxes

get_boxcenters Now calculate the magnetic
declina
tion for each chart. This requires as input the date when data were acquired:

mag_declins 1998.855 That creates a file
called $PARMS/geomag/boxes.mag_corrs, which contains the corrections for each chart. Look at the output:

more
$PARMS/geomag/boxes.
mag_corrs


...and cut and paste the declinations for the most current charts into the end of the doc
file $DOC/nav/mag_corr.doc (you'll need to edit that doc file to list the MR1 files that occur within that chart).

Towfish Compass Processing Survey rs9401r Reprocessing September 1999 A COOKBOOK For more info on how these scripts
work, or info on how to correctly
edit the FILTCONTROL control file, see $DOC/compass/filtcomp_info.doc Bathymetry
----------

1. Use
the script getcompbty.job to strip out compass data from processed bathymetry files. The script uses the MR1 program mrstr
ip.
Note: In order for the

compass filtering to work, you need to have compass data that extends several pings before and after the
time interval you're trying to filter. Because we're processing by julian day, we include the previous day's 2300 f
ile an
d the
next day's 0000 file in the filtering scheme set up below. set jd = 328 cd $BTYF/btyf$jd; ls MR*.btywtn > getcomp.fil
es foreach
file (`cat getcomp.files`) echo "Stripping compass data from file: "$file set f = $file:r

mrstrp
-
compass < $file >
$COMPASS/bathy/$f.comp end # Only run this when you are postprocessing an entire JD... cd $BTYR/btyr`expr $jd + 1`

set file
= MR1?????00.00.btywt set f = $file:r echo "Stripping compass data from file: "$fil
e mrstrp
-
compass < $file >
$COMPASS/bathy/$f.comp 2. Make a control file to direct how the files are processed during the filtering step. From any

directory,
type $SCRIPTS/filtcontrol bathy $jd : :.........Answer the ques
tions. :.........For more info on how to modify this file,
see :.........$DOC/compass/filtcomp_info.doc 3. Create the executable job that will filter the compass data. In

the
$COMPASS/bathy directory, execute the following: cd $C
OMPASS/bathy $SCRIPTS/make_filtcomp day$jd.control 7 98 4.
Execute the job: day$jd.filtcomp.job >& day$jd.filtcomp.log This job calls a script called $SCRIPTS/filtcomp, which i
n turn runs
the GMT program filter1d.


5. Insert the fil
tered data into the processed bathy files, using the script $SCRIPTS/recompbty.job.
cd $BTYF/btyf$jd ls MR*btywtn > files $SCRIPTS/recompbty.job btywtn btywtnc if the above is OK, then
\
rm *.btywtn
All Pau!

############################################################################## 1. How this file is used The values
in this file are used to correct towfish compass values to eliminate the influence of the Earth's magnetic field, which chang
es throug
h
time around the world. The data are incorporated into the bathymetry and sidescan processing in different ways: BATHYMETRY
uses
corrections on a file
-
by
-
file basis, and requires that the file name be listed in the first column below. Only include bath
ymetry files that
you want to grid (ie, don't include turns or pieces of data that you don't want plotted
--

this is how we kept unwanted bathy data out of
the charts). To see how the magnetic corrections are incorporated, see the doc file $DOC/bty_chart
/MR1_to_xyzw.doc. SIDESCAN
uses corrections on a chart
-
by
-
chart basis, and requires the prefix of the chart name in the first column. The declinations are called in
the gridding loop in the doc file $DOC/ss_chart/ss_grid.doc EXAMPLE of how to list the
data. Note that negative values require the
minus signs for both degrees and minutes:

Sidescan image proce
ssing using the ssjob script Survey rs9401r The sidescan data processing Scheme that worked best is hard
-
wired into the script SCRIPTS/ssjob. The Scheme is determined early in the survey, using the interactive program SSP to try
different
modules and fi
lters. See the script $SCRIPTS/ssjob_rs9401 for a description of each of the processing steps that were applied in the
ssjob script. Run this stuff on the .ss files located in $SSRAW. After you're done, the new files will have the suffix .ssd
, and will
stay in
$SSRAW.
-----------------

HISTORY Hey! document times of changes of ssjob parameters here.

Cookbook To process
all the sidescan data at once, run the following: cd $SSRAW foreach dir (` /bin/ls `) cd $SSRAW/$dir ls *ssn
> ssjob.files
ssjob_rs9401 ssjob.files ssn ssdn end To process a single file, try cd $SSRAW/ssr036 ls MR19403608.00.ssn > ssjob.files
ssjob_rs9401 ssjob.files ssn ssdn When pau, move the .ssdn files to $SSINT: set jd = 012 foreach jd ( 013 014 015

Towfish Compass Processing for Sidescan Data Survey rs9401r A COOKBOOK For more info on how these scripts work, or info on
how to correctly edit the FILTCONTROL
control file, see $DOC/compass_ovrvw.doc Sidescan
----------

1. Strip out compass data from

processed sidescan files. The routine below uses the MR1 program mrstrip.
Note: In order for the compass filtering to work, you need to have compass data that extends several pings before a
nd after the time interval you're tryin
g to filter.
Because we're processing by julian day, we include the previous day's 2300 file and the next day's 0000 fil
e in the filtering scheme set up below. set jd = 047
cd $SSINT/ssi$jd; ls MR*.ssdn > getcomp.files foreach f
ile (`cat getcomp.files`) echo "Stripping compass data from file: "$file set f = $file:r mrstrp
-
compass < $file
> $COMPASS/ss/$f.comp end # Only run the next block when you are postprocessing an entire JD... cd $SSRAW/ssr`
ech
o $jd | nawk '{printf "%3.3d
\
n", $1+1}' `
set file = MR1?????00.00.ssn set f = $file:r echo "Stripping compass data from file: "$file mrstrp
-
compass < $file > $COMPASS/ss/$f.comp 2. Make a control file to
direct how the files are processed d
uring the filtering step. From any directory, type $SCRIPTS/filtcontrol ss $jd : :.........Answe
r the questions. :.........For
more info on how to modify this file, see :.........$DOC/compass_ovrvw.doc 3. Creat
e the executable job that will filter the compass data. In the $COMPASS/bathy
directory, execute the following: cd $COMPASS/ss make_filtcomp day$jd.control 7 94 4. Execute the job: da
y$jd.filtcomp.job >& day$jd.filtcomp.log This

job
calls a script called $SCRIPTS/filtcomp, which in turn runs the GMT program filter1d. 5. Insert the filtered data into
the processed sidescan files, using the script
$SCRIPTS/recompss.job


cd $SSINT/ssi$jd ls *ssdn > files $SCRIPTS/
recompss.job ssdn ssdnc if the above is OK, then
\
rm *.ssdn All Pau!

##################################################################### 1.
Introduction This file shows you how to apply angle
-
varying gain (AVG) corrections to sidescan data. The mravg program is also used
here to remove high
-

amplitude specular reflecti
ons at nadir. This is often done with several iterative calls to mravg that use
progressively smaller values for the
-
swp and
-
ma options (see the mravg manpage for descriptions of the variables). These steps
should be done after the sidescan files have
been navigated and compass
-
corrected. To see how the AVG corrections were
generated, check out the file $DOC/ss_proc/make_AVG.doc.

A
pplying scaling factors to sidescan data Survey rs9401r # NOTE
-

So far this step has not been applied to the reprocessed
RS9401r data Following the AVG correction, each file should be run through mrscale to equalize the gray values between fil
es that
were acquired using different transmit power settings or pulse lengths. The procedure below requires a doc file
$DOC/ss_proc/ss_power.doc that contains power and pulse width settings.
##############################################################
####### Corrections for different power settings. These
corrections were determined empirically by 1) running ssp on a several AVG'd files (.ssdnca), and 2) using the "scale" proc
ess to
interactively view the scaled data:

############################################################################## 1. How this file is used The values in this f
ile are used to correct towfish
compass v
alues to eliminate the influence of the Earth's magnetic field, which changes through time around the world. The data are in
corporated into the bathymetry and
sidescan processing in different ways: BATHYMETRY uses corrections on a file
-
by
-
file basis, and

requires that the file name be listed in the first column below. Only include
bathymetry files that you want to grid (ie, don't include turns or pieces of data that you don't want plotted
--

this is how we kept unwanted bathy data out of the charts). T
o
see how the magnetic corrections are incorporated, see the doc file $DOC/bty_chart/MR1_to_xyzw.doc. SIDESCAN uses correction
s on a chart
-
by
-
chart basis, and requires
the prefix of the chart name in the first column. The declinations are called in the g
ridding loop in the doc file $DOC/ss_chart/ss_grid.doc EXAMPLE of how to list the data.
Note that negative values require the minus signs for both degrees and minutes:

Generating Angle Varying Gain (AVG)
Corrections Survey rs9401r CONTENTS 1. Summary 2. Cookbook
############################################################################# 1. Summary This is a method to
generate depth
-
dependent angle varying gain (AVG) corrections. When choosing the
input files to create final AVG curves, be sure to
include files that represent the extreme depth ranges of the data set. If you don't, then AVG corrections for those depth ran
ges won't be
calculated. The names of the files used to generate each AVG corre
ction are saved in $AVG/$table/$table.avglist To APPLY the AVG
correction, see the file $DOC/ss_proc/apply_AVG.doc On past surveys we've had good luck regenerating AVG corrections on a da
ily
basis, with new AVG tables using all the data from preceding da
ys. This method yielded pretty good matches between hour files that
were processed with different AVG corrections.

Bathymetry Charting: MR1 to XYZW Conversion Survey rs9401r CONTENTS 1. What This Does 2. Da Cookbook
#####################################################
####################### 1. What This Does Although the mr1
software allows you to grid and display bathymetry data, many people want to generate xyz bathymetry for their own evil purpo
ses. The
programs mr2gmt and mr2xyzw allow you to do this. We'll use
mr2xyzw to convert the data to values that are weighted such that points
closest to nadir have the most significance. The MR
-
> XYZ conversion was changed during japanus leg 3, to correct a problem that
caused adjacent charts to exhibit unacceptable level
s of mismatch where they overlapped. The new technique applies the noise
suppression and most of the GMT filtering on individual hour files. This results in less mismatch between adjacent charts, a
nd in
cleaner bathy overall. The conversion to xyz requ
ires an input file that contains magnetic corrections, in $DOC/nav/mag_corr.doc

Gridding MR1 Bathymetry by Chart Survey rs9401r CONTENTS 1. How this works 2. Gridding commands
############################################################################ 1. How this works It's easy. All the
hard stuff is neatly entombed in the scr
ipts btygrid_utm_100k, btygrid_utm_025k, and btygrid_utm_010k. If you want to see how they
work, have a look at them in the $SCRIPTS directory. As currently configured, the gridding scripts: 1) Need an input file

called
$PARMS/chart/boxes that contain
s the boundaries for all the charts. 2) Require individual box definition files ($PARMS/chart/*.box)
3) extend the gridded area 3 minutes beyond the plot edges defined in $PARMS/chart/boxes

Imaging Charts Survey rs9401r CONTENTS 1. How this works 2. Doing it
############################################################################ 1. How this works Again, easy. All
the hard stuff is neatly entombed in the scripts btyimage_utm_100k, btyimage_utm_25k, and btyimage_utm_10k. If you want to s
ee
how they work
, have a look at them in the $SCRIPTS directory. The imaging scripts require several files as input:
$PARMS/chart/rpl.xy $PARMS/chart/rpl.sym.xy $PARMS/chart/chartlabels.dat $PARMS/chart/boxes For survey japanus, there
were many segments which ea
ch required different .xy, .dat and boxes files. These were stored in subdirectories named
$PARMS/chart/JU:## (where ## is the segment number). In order to plot the correct information on each segment's plots, these

files
were copied into the $PARMS/char
t directory before their charts were created.

Combine sidescan with GMT framt Survey rs9401r CONTENTS 1. Determine chart offset 2. Create GMT sidescan frames 3. Merge
sidescan raster with GMT postscript ######################################################################## 1.
Determi
ne the chart offset. You need to find the (x,y) values of the GMT chart frame raster in order to properly position the side
scan
raster within the frame. First you need to generate a GMT frame: ssframe_utm_100k JU:09:100
-
001 10 09 Now rasterize th
e
frame: cd $CHART/ss/ssJU:09:100
-
001 ps2rast
-
r 300
-
Y 47.5
-
X 33.5
-
d 24 ssJU:09:100
-
001.ps test.frame.ras Find the (x,y) value
of the corner of a GMT frame raster named test.frame.ras using the program xv: xv test.frame.ras Place the tip

of the mouse
arrow over the NE corner of the lat/lon frame and hold down the center mouse button. XV will display the (x,y) values of

the cursor.


RESULT: X = 292 Y = 3370 These values will be used later (step 3 below), when you combine the GMT
and MR1 rasters using the program rasmask. But here's an example now: rasmask
-
f $chart.frame.ras

3370 < $chart.2x.ras >
$chart.tmp.ras ######################################################################## 2. Create GMT sidescan
frames

This is easy. All the hard stuff is neatly entombed in the scripts ssframe_utm_100k, ssframe_utm_25k, and ssframe_utm_10k.
If you want to see how they work, have a look at them in the $SCRIPTS directory. The imaging scripts require several files a
s inp
ut:
$PARMS/chart/rpl.xy $PARMS/chart/rpl.sym.xy $PARMS/chart/chartlabels.dat $PARMS/chart/boxes For survey japanus, there
were many segments which each required different .xy, .dat and boxes files. These were stored in subdirectories named
$PARMS
/chart/JU:## (where ## is the segment number). In order to plot the correct information on each segment's plots, these files

were copied into the $PARMS/chart directory before their charts were created. Here we go:
\
cp
$PARMS/chart/JU:02/JU:02.rpl_late
st.xy $PARMS/chart/rpl.xy
\
cp $PARMS/chart/JU:02/JU:02.rpl_latest.ac.xy
$PARMS/chart/rpl.sym.xy
\
cp $PARMS/chart/JU:02/JU:02.chartlabels.dat $PARMS/chart/chartlabels.dat
\
cp
$PARMS/chart/JU:02/JU:02.boxes $PARMS/chart/boxes 1:100,000 chart frame: ssfram

-
003 04 02
######################################################################## 3. Merge sidescan raster wi
th GMT
postscript Now its time to combine the GMT frame with the MR1 sidescan raster. This step involves turning the GMT Postscript

into a
Sun raster file, processing the sidescan mosaic through pnm software, combining the two rasters using rasmask, reduc
ing the size of
the output raster (from ~450 mb to ~ 25 mb) using pnm software, and converting the final image into HP RTL format for printin
g on the
HP755 plotter. It's a for/each loop (you need to indicate the chart number(s) to plot): cd $CHART/ss fo

sized GMT
frame Its SO easy. All the hard stuff is tucked away in the script ssframe_japanus_page. If you want to see it works, have

a look at it
in the $SCRIPTS directory. The imaging

scripts require several files as input: $PARMS/chart/rpl.xy $PARMS/chart/rpl.sym.xy
$PARMS/chart/chartlabels.dat $PARMS/chart/boxes For survey japanus, there were many segments which each required different

.xy, .dat and boxes files. These were
stored in subdirectories named $PARMS/chart/JU:## (where ## is the segment number). In
order to plot the correct information on each segment's plots, these files were copied into the $PARMS/chart directory before

their
charts were created. Here we go:
\
cp $PARMS/chart/JU:02/JU:02.10.23.98.xy $PARMS/chart/rpl.xy
\
cp
$PARMS/chart/JU:02/JU:02.10.23.98.ac.xy $PARMS/chart/rpl.sym.xy
\
cp $PARMS/chart/JU:02/JU:02.chartlabels.dat
$PARMS/chart/chartlabels.dat

02 ######################################################################## 2. Combine GMT frame with sidescan
raster The following loop works like this: 1. Uses ps2rast (an alchemy script) to convert the GMT fram
e from PostScript to a Sun
rasterfile; 2. Uses pnm software to scale, rotate, and gamma
-
shift the sidescan image; 3. Uses rasmask to overlay the GMT frame on
the sidescan image; 4. Uses pnm software to convert the final image from 32
-
bit to 8
-
bit (redu
ces the size of the image without
sacrificing image quality); and 5. Uses alchemy to create an HP Raster Transfer Language (.rtl) file that can be plotted o
n the HP755
large
-
format plotter. It's a for/each loop (you need to indicate the chart number
(s) to plot): cd $CHART/ss foreach c ( 093 ) set chart =

x
files ############################################################################ 1. Overview of the technique
The scripts t
hat construct the bathymetry and sidescan charts require a chart definition file, which we call a "box" file. The cookbook
below shows you how to create these box files. Box files should be located in the directory $PARMS/chart (or, for complex su
rveys,
in
subdirectories beneath $PARMS/chart) and have the suffix ".box". In addition, all the .box files should be concatinated into
a single file
($PARMS/chart/boxes) that contains all the boxes. The geographic area imaged within each chart is determined by
figuring out how
big a space (in inches) is available for printing within the chart format. The A0
-
size chart format we've developed allows you to plot an
area that is 31.49610" wide by 23.42520" tall. To determine the lat/lon bounds for each chart that c
onform to these measurements,
you'll use the script make_boundbox (Step 4 below).
############################################################################ 2. Your Mission Your mission is to
create adjacent charts that have enough overlap so that y
ou capture all the swath data without creating too many charts. Here's how:
1. Create a chart box by specifying the lower
-
left corner of the chart on the make_boundbox command line. 2. Make a page
-
sized nav
chart to check the degree of overlap with ad
jacent charts. Use the method shown in $DOC/nav/nav_plot.doc. The boundaries of
other charts are plotted as dashed lines, which allows you to determine whether there's enough overlap to accommodate the
full
sidescan swath. 3. Make a page
-
sized re
gional trackline plot, which automatically plots the positions of each chart. 4. If the chart area
is OK, move on. If its not, go directly to Step 1 above.
############################################################################ 3. The make_boun
dbox script The
script make_boundbox calculates the four corners of each chart, based on info that you provide on the command line. The outp
ut from
make_boundbox is formatted such that it can be input directly into other HMRG scripts and GMT programs.

The general form of the
command is like this: make_boundbox chart_ID minlon minlat x_inches y_inches dpi proj scale make_boundbox JU:01:100

charts when they're plotted on chart keys, legends, or regional trackline plots. The
make_labels script requires the file $PARMS/chart/boxes, which contains the boundary information for each chart. Output from

make_labels is in a format that can be read
by the GMT program pstext, written in a file named chartlabels.dat located in the directory
$PARMS/chart ######################################################################### 2. The make_labels script
The general form of the command is like this:
make_labels chart_ID offset posn fontsize font label_text make_labels SMW:100
-
001 $off br $size $font 001
-

Offset is in inches (a good value is .03)
-

Fontsize is in points
-

Font numbers are identified in the
GMTDEFAULTS man page
-

label_text is the text string that actually gets printed
-

Position categories:



c =
center tl = top left rt = right top br = bottom right lb = left bottom tc = top center rc = right center b
c = bottom center lc =
left
center tr = top right rb = right bottom bl = bottom left lt = left top
