== Aim and Objectives ==
'''Purpose of test:''' To evaluate SPC's ability to represent a simplified 'boulder' (a peak) which has a constant 20 degree slope.

'''Additional Objectives'''

 * To investigate the effect of varying the combinations of viewing conditions which comprise the image suite, specifically:
  * Variation of spacecraft azimuth;
  * Variation of sun zenith (incidence);
  * Variation of spacecraft zenith (emission angle);
 * To investigate the effect of the number of images and viewing conditions which comprise the image suite.

== Methodology ==
The 'boulder' was simulated by generating a simple axi-symmetric, flat-topped cone (peak) with a constant 20 degree slope. Two boulder simulations were generated:

 * A single peak in an otherwise flat landscape of width 5m - Modeled using a single maplet (no overlaps).
 * Multiple peaks and (simplified) craters in an otherwise flat landscape of width approx. 22.5m.

'''Data'''

 * Data was generated by ??.
 * Image resolutions: 2cm/pixel.

Test 11: ReferencePeaks

Aim and Objectives

Purpose of test: To evaluate SPC's ability to represent a simplified 'boulder' (a peak) which has a constant 20 degree slope.

Additional Objectives

  • To investigate the effect of varying the combinations of viewing conditions which comprise the image suite, specifically:
    • Variation of spacecraft azimuth;
    • Variation of sun zenith (incidence);
    • Variation of spacecraft zenith (emission angle);
  • To investigate the effect of the number of images and viewing conditions which comprise the image suite.

Methodology

The 'boulder' was simulated by generating a simple axi-symmetric, flat-topped cone (peak) with a constant 20 degree slope. Two boulder simulations were generated:

  • A single peak in an otherwise flat landscape of width 5m - Modeled using a single maplet (no overlaps).
  • Multiple peaks and (simplified) craters in an otherwise flat landscape of width approx. 22.5m.

Data

  • Data was generated by ??.
  • Image resolutions: 2cm/pixel.

Planned Tests

Please follow embedded links for test results.

Take PIT020 as the only maplet in MAPLIST.TXT. Generate 5cm images of the topography (which is based at TAG Site 1). Then we build a MAPLET, saving the MAPLETs flatMapVect at several states.

Simple Variations

Groups of images - (adjusted for 5cm)

  • Test11A - Detailed Survey. Eric (Has 11 images, very low in sample space)
  • Test11B - Min Orbit B (by hand, calculate the minimum requirement)
  • Test11C - Average Orbit B (use a random Orbit B solution with 3 unique observation/illumination conditions)
  • Test11D - Best Orbit B (as we did before)
  • Test11E - Optimum Collection (as we did before)

Test Set-Up

Hill Data

I have created the following hills for testing

  • REGION - Includes lots of craters and a few 20 deg peaks

Truth Maplets

  • -8.027 262.768
  • T11TRU.MAP - already built. It has the truth heights loaded from PIT020.
  • T11TRU.TXT -- Text file of the maplet. Use for plotting transits
  • t11-truth.obj -- OBJ file for testing using CompareOBJ

Testing Maplets

  • -8.027 262.768
  • Build a model MAPLET using TAG Site 1 center position (5cm resolution and Q=49). Do not load a base map for topography
  • Create MOD20#, which # is the test number (letter)
  • Align the images with the key location at 50/50.
  • Build template with 100
  • (Skip until close to perfect) -- Do an auto align
  • Build height using the iteration template
  • Do flatMapVec and rename it to mod-20#-1
  • Do compMapVec between MOD20# and T11TRU
  • Repeat as necessary

Save States

The goal is to see the evolution of the model over time. You can stop iterations once the peak and base are stable. The most likely tool to evaluate if the model has reached it best fit will be transit.

Save the flatMapVect statistics at the following number of iterations

  • 1st
  • 2nd
  • 3rd
  • 5th
  • 10th
  • 15th
  • 20th
  • 50th (if needed)
  • 100th (if needed)
  • 200th (if needed)
