Spacecraft Zenith 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 S, T & U, Spacecraft Zenith Variations

To investigate the effect of varying the combination of spacecraft zenith (emission angle) 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 axe-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.

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).

Step	GSD	Overlap Ratio	Q Size	Width	Center
START.MAP	20cm	-	49	20m	REGION.MAP p/l 1125, 1125 (center)
10cm-Tiling	10cm	1.3	130	20m	START1.MAP, p/l 49, 49
5cm-Tiling	5cm	1.3	250	20m	START1.MAP, p/l 49, 49
5cm-Iterations	5cm	-	-	20m	START1.MAP, p/l 49, 49
Evaluation Map	1cm	-	200	4m	REGION.MAP, p/l 996, 1005

Data

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

Name	Sun	S/C Az	S/C Zenith	Total Number of Images
Test11S	45, 0, -45	every 45	0, 30, 60	80
Test11T	45, 0, -45	every 45	0, 20, 40, 60	112
Test11U	45, 0, -45	every 45	0, 15, 30, 45, 60	144

Note that a larger image suite was planned and produced than was utilized during test. The images for a number of planned viewing conditions were eliminated due to image quality related to the viewing conditions being unfit for SPC. For further details are contained here:
