Here is what to do:
- first, run the BATCH file MYDATA.BAT:
<as the user account you are setting things up in>
cd $MCDATA
batch.k MYDATA.BAT
This creates 4 ADDE datasets:
MYDATA/GRIDS
MYDATA/IMAGES
MYDATA/PTSRCS
MYDATA/TOPO
The dataset MYDATA/IMAGES can contain all images in AREA format named using
the McIDAS AREA naming convention (e.g., AREA0001, AREA002, ..., AREA9999)
You will use the MYDATA/IMAGES dataset as the target for the IMGREMAP output.
- next, decide which dataset you want to use as the input to IMGREMAP. If you
intend to use the Unidata-Wisconsin imagery, they should already be accessible
using the RTIMAGES/<type> datasets (e.g., RTIMAGES/GE-IR, RTIMAGES/GW-IR,
etc.).
To see the list of all datasets available in the RTIMAGES group, use the
DSINFO command.
For instance, if you are runing as the user 'mcidas' on metofis, run:
cd $MCDATA
dataloc.k LIST RTIMAGES <- make sure that the source is either LOCAL-DATA or
metofis.rsmas.miami.edu
dsinfo.k IMAGE RTIMAGES
- next, use IMGREMAP to remap an input image to an output image.
For instance, let's remap the most recent GOES-East thermal IR (10.7 um) image
in to one with a MERCator projection such that the output image is:
- centered on 30N,60W
- is 800x800 (linesXelements) in size
- the effective resolution of the remapped image is 4 km
<again, assuming that you are running as 'mcidas'>
cd $MCDATA
imgremap.k RTIMAGES/GE-IR MYDATA/IMAGES.3000 LAT=30 60 SSIZE=ALL SIZE=800 800
PRO=MERC RES=4
This will create an image in the file AREA3000. This file should be located
in your $MCDATA directory.
Now, if you want to generate a web-viewable form (e.g., GIF), I would do the
following:
mcenv -f address@hidden
imgdisp.k MYDATA/IMAGES.3000 LAT=30 60
map.k SAT
frmsave.k 1 mercremap.gif
exit
Some notes:
1) You could wrap the entire sequence in a single 'mcenv' invocation:
cd $MCDATA
mcenv -f address@hidden
imgremap.k RTIMAGES/GE-IR MYDATA/IMAGES.3000 LAT=30 60 SSIZE=ALL SIZE=800 800
PRO=MERC RES=4
imgdisp.k MYDATA/IMAGES.3000 LAT=30 6
map.k SAT
frmsave.k 1 mercremap.gif
exit
2) instead of remapping the latest image from RTIMAGES/GE-IR, you could pick
the time
you wanted:
imglist.k RTIMAGE/GE-IR.-15
imgremap.k RTIMAGES/GE-IR MYDATA/IMAGES.3000 LAT=30 60 SSIZE=ALL SIZE=800 800
PRO=MERC RES=4 DAY=2008079 TIME=22:45
3) you could use an example script provided in the Unidata McIDAS distribution
to simplify
your processing:
cd $MCDATA
cp ~mcidas/data/mcrun.sh myrun.sh
-- edit myrun.sh and include the set of McIDAS commands you want to process
in the block that looks like (snippit from mcrun.sh near the bottom):
...
cd $MCDATA
mcenv << EOF
# put McIDAS-X commands you want to run here, one command per line.
# Example (note that these lines are commented out!!):
#
# dataloc.k ADD GINIEAST adde.ucar.edu
# eg.k
# imgdisp.k GINIEAST/GE1KVIS STA=KMIA MAG=-2 EU=IMAGE SF=YES
# map.k H
# bar.k
# frmsave.k 1 miamivis.gif
# done
exit
EOF
Just make sure to not use the file included in the distribution as it will
be overwritten with the next McIDAS installation (i.e., rename the script)
4) you could put all of the McIDAS commands into a McIDAS BATCH file and use
the mcbatch.sh script that is included with the Unidata McIDAS distribution.
For instance:
- create $MCDATA/REMAPIT.BAT with the following content:
IMGREMAP RTIMAGES/GE-IR MYDATA/IMAGES.3000 LAT=30 60 SSIZE=ALL SIZE=800 800
PRO=MERC RES=4
IMGDISP MYDATA/IMAGES.3000 LAT=30 6
MAP SAT
FRMSAVE 1 mercremap.gif
- now, execute the REMAPIT.BAT content using mcbatch.sh:
mcbatch.sh REMAPIT.BAT
N.B.:
The McIDAS session created by mcbatch.sh has a frame size of 640x480, not
800x800. You may want to create your own copy of mcbatch.sh (e.g.,
mybatch.sh)
and edit it to specify the frame size in the 'mcenv' clause.
For example:
cd $MCDATA
cp ~mcidas/data/mcbatch.sh mybatch.sh
-- edit mybatch.sh and
change:
mcenv << EOF
batch.k $1
exit
EOF
to:
mcenv -f address@hidden -i 128 -g 16 << EOF
batch.k $1
exit
EOF
5) etc.
> Thanks,
No worries.
Cheers,
Tom
