= Overview =

Archiving SPC-focus products.  There are two major categories (global and regional) with two subdivisions (topography and backplanes -- aka other data).  The regional products are derived from bigmaps.

=== Tools ===
These tools are stored in GitHub as [[https://github.com/StereoPhotoClinometry/archivingTools|archivingTools]].


 * [[convertLatLon]] - Reads an X,Y,Z (or X,Y,Z,V) list and converts it into lat, lon, distance or lat, lon, value
 * [[backplanesGMT]] - Reads a bigmap and generates a list of latlon, radius, albedo, slope.  Use paste latlon radius > tmp for GMT. 
 * [[backplanesISIS]] - Reads a bigmap and generates 2D matrix for radius, albedo, slope, lat, lon
 * [[phasei]] - Reads a bigmap and image (the SUMFILE) and generates 2D matrix for incidence, emission, phase angles
 * coverage_p_low -- Reads all images and maplets.  Creates a pgm that has every pixel marked for every image that it has, counter is only 1.
 * [[map_coverage_p_low]] - Counts the number of images that cover each bigmap pixel.  Creates MAPNM-cov.txt and MAPNM-cov.pgm
 * [[bustGrid]] - Takes an ascii grid output and puts each entry on its own line.  Needed to take grid and paste it with lat/lon to make grid

Run backplanesGMT (which is in ORExSPCsupport) (or backplanesISIS)

== Slope ==

* See topography

== Albedo ==
* See topography

== Sigmas ==

 * Run backplanesGMT (this gets lon/lat only file)
 * Take the SIGMAS.pgm and convert it to lon/lat/val files

   {{{
   name=EQLEAD
   std2isis from=SIGMAS.pgm to=tmp.cub
   isis2ascii from=tmp.cub to=tmp1.txt
   sed '1,2d' tmp1.txt > tmp2.txt
    ~/bin/bustGrid tmp2.txt > tmp3.txt
   paste $name-lonlat.txt tmp3.txt > sigma.ll
   var=sigma.ll
   }}}
 * Continue with topography script


== Number of Images ==


 * run map_coverage_p_low
 * Convert coverage out to lon/lat/value
   {{{
   name=EQLEAD
   bustGrid $name-cov.txt > tmp1.txt
   paste lonlat.txt tmp1.txt > imgNum.ll
   var=imgNum.ll
   }}}
 
* Continue with topography script


== Photometric Data ==

This includes emission angle, incidence angle and phase angle.

Run phasei (located in ORExSPCsupport)

Use Dropbox spcShare directory

 {{{
cd /opt/local/spc/
relink ~/Dropbox/spcShare/Tethys .
 }}}

Then in the working directory


 {{{
relink.sh /opt/local/spc/Tethys/support .
relink.sh /opt/local/spc/Tethys/mapConfig .
