WIKI for Bob Gaskell's StereoPC

General Info

This is an attempt to document of some of the key programs and support files for Stereo Photoclinometry. I've been taking pretty good notes, and I thought we could all share and benefit from what we each have learned. If you figure something out (or get help from Bob himself), be sure to post it. If you need help with the wiki, let me know (or just send me the info).

• General_Parameters - Resolution scale, etc.

• Questions_to_ask - When I talk to Bob, these are things I am wondering

• Table_of_Contents_For_User's_Manual - We will come up with a table of contents for OSIRIS SPC. Here is where I will be putting my notes. Other's with suggestions are welcome.

• Training_Notes - Eric's notes for what to introduce and how

• SPC_V_and_V_testing - Directions and guideline for testing

• SPOC v3.02A PDF

• SPOC v3.02A html directory

Versions

• 1.0 -- Initial version of SPC
• 2.0 -- Version of SPC with the Common library created

• 2.1A7 -- This is the baseline version of Gaskell's software. I has gone under SubComponent testing

• 3.0A0 -- These have changed required in SPC to finish the SubComponent testing. It changed regress, process_fits and geometry

Work Flow

Building Landmarks

• Making_new_landmarks - Workflow from the 50m resolution work done for Dawn at Vesta

• Basic_tiling - The core procedures for tile a bigmap

• LatLon_tiling - Tiling using Lat/Lon. Used for the initial sets of landmarks

• Export_Import - Build landmarks on other machines and export them and import them

Test Procedure

• Standard_iteration - Runs lithosP

• Adding new images - How to run autoregister

• Building a shape model - How to run densify

Problems

• Fill_procedure -- Replace current topography with shape or bigmap. Fixes problems

• Fixing_problem_landmarks -- Techniques to deal with landmarks that don't work well

  • When to Fix Landmarks - When?

  • Basic Procedure -- Simple way to fix landmarks using lithos that usually works.

  • Aligning to a Single Image -- What to do if initial image alignment shows no to very miniscule correlation.

  • Manually Moving An Image -- What to do when some images (that you want/need to use for building template) won't auto correlate.

• Obsolete Small_Footprint_Processing - Lets you do tiling copying only the files that you need for the specific task.

Programs

Lithos

• lithos.e - aligns maplets to the current shape model and will provide slight changes to the shape (stored in MAPFILES)

• geometry - figures out a surface based on landmarks

• residuals.e - figures out a surface based on landmarks

• register - aligns a new image with a reference, manually

• autoregister - adds groups of landmarks to an image

• convert

• make_sumfiles

• dynamics

Imager

• map_coverage.e - shows the coverage that has been processed by resolution

• coverage.e - shows the global coverage that has been processed by resolution

• image_map_mono.e -

• image_map_rgb.e - Renders a 3D image of a bigmap using red and blue

• image_map_stereo.e -

• view_shape.e - The generates a point-of-view image of the shape model

• panaroma.e - Makes a 360 degree panaroma image from a big map

• surface_imager.e - Makes an image using a surface point of view from a big map

• display.e - Appears to generate an image that shows the location of landmarks on it

• mosaic - Creates a mosaic of images registered to the shape model

Shaper

• bigmap - processes maplets to form a bigmap

• spheremapB.e - This reads the Zmap files and makes the resulting map line by line.

• update_infiles.e - generates a list of landmarks and headers for showing coverage

Utilities

• find_nofitT.e - searches for alignments that had problems

• export.e - builds scripts to package up the new maplets/landmarks into a tar ball

• importL.e - builds script to unpack maplets/landmarks and integrate into a master directory

• make_scriptT.e make_scriptT - generates the script that tiles (makes new maplets)

• refresh_sumfiles.e - updates the sumfiles to match the maplets

• showmap.e - generates an image (.pgm) for a specific bigmap

• pr_template - (copy the codes for when making a new prog page)

• make_pictlistX - Builds the file PICTLISTX.TXT which makes things run faster

• process_img - Takes a list of files and creates make_sumfiles.in. Creates IMAGEFILE for each images

• make_sumfiles - Computes the SUMFILE and NOMINALS

Gravity

Notes_on_Gravity

• Mgrav.e - Makes MGRAV.TXT and generates gravity images based on a map or bigmap.

• Sgrav.e - Makes a file called SGRAV.TXT that is like SHAPE.TXT but with extra columns for surface acceleration, potential and laplacian (just as a check). Based on a shape model. This is for a non-rotating body with GM=1.

• Sacc.e - Provided the correct GM and Omega, it will use SGRAV.TXT file to create the surface acceleration.

• Selv.e - Provided the correct GM and Omega, it will use SGRAV.TXT file to create the surface elevation (same as geoid).

• Slap - Provided the correct GM and Omega, it will use SGRAV.TXT file to create the surface laplacian.

• Spot.e - Provided the correct GM and Omega, it will use SGRAV.TXT file to create the surface potential.

• Sslpa.e - ?

Deprecated

• view_maps.in - A list of all the maplets to be used in view_maps.e. The first line isn't read. The file should be terminated with "END"
