Description
RESIDUALS.TXT is a report created by residuals that looks for bad landmarks.
A basic description of the information in RESIDUALS.TXT.
- The post-fit residuals between predicted and actual control point positions in all images are captured in the residuals file
- The post-fit residuals between predicted and actual control point difference between adjacent, overlapping maplets are captured in the residuals file
- Outliers in both quantities are flagged automatically based on input threshold criteria
A more in depth list explaining the information in the RESIDUALS.TXT file is shown below.
- In between the dot rows:
- The name of a landmark
- T (landmark has a map with it) or F (flat landmark, no image)
- Resolution
- Lat of landmark
- Wlon of landmark
- Radius
- Below the dot rows with the landmark name above them:
- For each image:
- 1st column - picture name
- 2nd column - PX residual (# of pixels in image resolution)
- 3rd column - LN residual (# of pixels in image resolution)
- 4th column - magnitude of PX and LN residuals (# of pixels in image resolution)
- 5th column - the estimate linear residual (km)
- For each overlap:
- 1st column - overlap name
- 2nd column - X residual (km)
- 3rd column - Y residual (km)
- 4rd column - Z residual (km)
- 5th column - estimate linear residual (km)
- For each limb apperation:
- 1st column - picture name
- 2nd column - PX residual (# of pixels in image resolution)
- 3rd column - LN residual (# of pixels in image resolution)
- 4th column - magnitude of PX and LN residuals (# of pixels in image resolution)
- 5th column - the estimate linear residual (km)
- For each image:
- Below the images, overlaps, and limbs list for a landmark:
- Landmark name
- Scalar difference between predicted and actual control point (landmark) in meters
- Below the single dot row at the very bottom of the image:
- Observations - how many IMAGEFILES, overlaps, and limbs for all landmarks
- RMS RESIDUAL - overall RMS linear residual in meters.
