Test 08: OptimalUltraF2

Purpose of test: To obtain highest possible topographic accuracy and resolution for TAG site 1, given perfect camera position and pointing and optimal SPC image suite. This test is an extension of OptimalF2 with 1cm and 0.5cm resolution images included in the image suite.

Data

Data was generated by Imager_mg using shape3.8 on ormacsrv1.

PT10A - Centered at the middle of TAG site one.

Image Suite: Optimal flight path, resolutions: 50cm, 20cm, 10cm, 5cm, 1cm, 0.5cm.

emission

Every 20 degrees azimuth, 45 zenith angle

incidence

0, 90, 180, 270 azimuth, 45 zenith angle

135 azimuth, 30 zenith angle

The following TAG1 bigmaps were tiled and evaluated:

Test Step	Ground Sample Distance (cm)	Maplet Overlap Factor	Approx. Maplet Overlap	Q size	Bigmap Width
2.5cm-Tiling	2.5cm	1/1.3	60%	200	8m
1.25cm-Tiling	1.25cm	1/1.3	60%	200	4m
0.75cm-Tiling	0.75cm	1/1.3	60%	200	2.3m
0.35cm-Tiling	0.35cm	1/1.3	60%	200	1.1m
Evaluation	0.38cm	N/A	N/A	100	0.76m

Results

RMS Distance (cm) - Compare OBJ

Note: For the interim tests, statistics were obtained for the last snapshot of OptimalF2 on the reduced evaluation area. These results show the reduction in RMS and formal uncertainty simply due to reducing the evaluation area.
