Test11 K-R (JRW)

Aim and Objectives

Purpose of test: Do determine the effect of sun zenith on the quality of the final solution produced by SPC.

Methodology

Data

• Topography was generated by EP that had 20deg sloped boulders and regular simple craters.
• We chose to analyze a boulder near the center of the region created by EP.
• Image suite (below) of 2cm/px images.

Bigmaps

The following bigmaps were tiled/iterated and evaluated:

Starting topography defined from: START1 created at 20cm from REGION.MAP

Iteration Parameters

Reset albedo/slopes: NO

Calculate Central Vector: YES

Differential Stereo: YES

Shadows: YES

Iterate Seed

# This script performs two maplet iterations in parallel mode. 
# It reinitializes slope and albedo.
# It recomputes maplet overlaps.
# It recomputes limb fits.
# It recomputes central maplet vector.
# Topography determination from slopes is conditioned by:
#   Initial topography, 
#   Overlapping topography, 
#   Shadowing, 
#   Differential stereo, 
#   Limb heghts. 
# Dataless area slopes are set from the shape model.
#
# The script hides most of the screen output.  In order to obtain the 
# full display replace H* by #H*.
