CTX process all script

[thare]

Here is a simple CShell script to help with CTX processing. It requires ISIS3 to be installed on SUSE, Solaris, or MacOSX. It will process all the required ISIS3 CTX steps and return map projected ISIS cubes and GIS-ready PNGs with worldfiles.

Not sure why I used cshell script as I usually write this stuff in PERL? I haven't tested it on Sun or Mac yet but it should work.

please test and modify as you wish,
Trent

Overview:

0.) Download script below (must be logged in to see attachment). In UNIX run chmod to make the script executable.
>chmod +x CTX_process_all.script.txt

note: I had to add a *.txt onto the script to attach it here. Normally I use a .script extension only.

1.) To help grab the CTX PDS images, use the PDS site, download the GIS footprints (I think this is the easiest) for use in a GIS or use pigwad to select the footprints you want. For the non-PDS methods, copy and paste the "DATA_LINK" files into a text file and prepend each line with "wget".
example:
wget http://pdsimg.jpl.nasa.gov/data/mro/mars_reconnaissance_orbiter/ctx/mrox_0003/data/T01_000806_2651_XN_85N014W.IMG
wget http://pdsimg.jpl.nasa.gov/data/mro/mars_reconnaissance_orbiter/ctx/mrox_0003/data/T01_000807_2638_XN_83N035W.IMG
...

The CTX footprints: ftp://ftpflag.wr.usgs.gov/dist/pigpen/mars/ctx/footprints/


2.) Before running you must first create a map file.
Use ISIS3's "maptemplate" program to create *.map. Here is the listing for a minimal N. Pole projection:
>cat npolar90.map

Thanks. Works nicely.

Thank you so much for this.. BTW - Tested on MAC, worked fine!

Hi all,

I have just one recommandation:

at cam2map step, the current script won't take into account the PixRes (pixel resolution) of the map_file.map. So if mosaicking is needed afterwards, you have to change the line #80 by:

[kainus]

This is a Trent Hare script (Thanks Trent) to process CTX .img's to map projected, losslessly compressed, JPG2000 images. The conversion from lev2 cub files into jp2 format using the gdal commands is the only change between this script and Trent's other script posted above. You will still need a maptemplate .map file and it still runs in ISIS3.

If you plan to use or mosaic in most GIS apps they don't need to be the same resolution. If you want to mosaic in ISIS, then you want the same resolution, so use Adakite's tip.

When you're saving it to your special saving place, delete the .txt extension. Source or chmod the file and you're ready to go, e.g.

chmod +x CTX_process_all_jp2.csh

Enjoy.
