= 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

||Step||GSD||Overlap Ratio||Q Size||Width||
||10cm-Tiling||10||1.3||49||
||5cm-Tiling||05||1.3||49||

'''Iteration Parameters'''

Reset albedo/slopes: NO

'''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*.
