Spacecraft Azimuth Variations
Aim and Objectives
Purpose of Test 11: To evaluate SPC's ability to represent a simplified 'boulder' which has a constant 20 degree slope.
Objective for Test 11 F, G, H, I & J, Spacecraft Azimuth Variations
- To investigate the effect of varying the combination of spacecraft azimuths with respect to a landmark contained in the image suite;
- To investigate the effect of the number of images and viewing conditions.
Methodology
The 'boulder' was simulated by generating a simple axi-symmetric, flat-topped cone (peak) with a constant 20 degree slope. Multiple peaks and (simplified) craters are randomly placed in an otherwise flat landscape of width approx. 22.5m.
Entire Truth map: REGION.MAP
Bigmaps
The following TAG1 bigmaps were tiled/iterated and evaluated:
Starting topography defined from: START1.MAP at pixel/line location 49, 49 (= REGION.MAP at p/l 1125, 1125).
