Photo Positions
Photo Position Uncertainties
Position Uncertainties: Top view (XY plane), side view (ZY plane) and front view (XZ plane) of computed photo positions (black dots). Blueellipses indicate the position uncertainty, scaled for readability. The minimum and maximum values, as well as the average value, can befound in the table below.

Mean 0.0154 0.0131 0.0054
Maximum 0.0375 0.0285 0.0183
For more information on individual photos, please refer to the Photos Report.
Distance to Input Positions
Position Distance to Metadata: Top view (XY plane), side view (ZY plane) and front view (XZ plane), with arrows indicating the o�set betweenthe metadata positions and the computed photo positions; all arrows start from the metadata positions and point toward the computedpositions. Gray points indicate uncalibrated photos that have metadata. Pink points indicate calibrated photos that have no metadata. The values are in meters, with a minimum distance of 0.0002 meters and a maximum of 0.0452 meters. The median position distance equals0.008 meters.
Scene Coverage
Number of photos seeing the scene: Top view (XY plane) display of the scene, with colors indicating the number of photos that potentiallysee each area.

Tie Point Position Uncertainties
Position Uncertainties: Top view (XY plane), side view (ZY plane) and front view (XZ plane) displays of all tie points, with colors representinguncertainty in the individual point position. The values are in meters, with a minimum uncertainty of 0.017 meters and a maximum of 0.4299meters. The median position uncertainty equals 0.102 meters.
Number of Photos Observing the Tie Points
Number of Observations per Tie Point: Top view (XY plane), side view (ZY plane) and front view (XZ plane) displays of all tie points, with colorsrepresenting the number of photos that have been used to de�ne each point. The minimum number of photos per tie point is 3 and themaximum is 38. The average number of photos observing a tie point is 7.
Reprojection Error
Reprojection Errors per Tie Point: Top view (XY plane), side view (ZY plane) and front view (XZ plane) displays of all tie points, with colorsrepresenting the reprojection error in pixels. The minimum reprojection error is 0.01 pixels and the maximum is 1.91 pixels. The averagereprojection error is 0.61 pixels.
Tie Point Resolution
Resolution: Top view (XY plane), side view (ZY plane) and front view (XZ plane) displays of all tie points, with colors representing resolution inthe individual point position. The values are in meters/pixel, with a minimum resolution of 0.0412 meters/pixel and a maximum of 0.0795meters/pixel. The median resolution equals 0.054 meters/pixel.
