Input Project
The path and file name of the OrthoEngine project file (*.prj) in which you want to refine TPs.
Output Folder
The path and name of the folder to which to write the output files.
Project Base Name
The base name to use to prepend the names of the output files. That is, the value you specify is used as a prefix for each output file.
Specifying a base name for the output files helps you identify the files (and content thereof) according to the prefix.
Send Email
If necessary, you can set up CATALYST Enterprise to send an email notification on job start and job completion.
With this check box selected, an email message is sent to each address specified in the Email Addresses box after the job starts and on completion.
You can specify one or more addresses, and each must be separated by a comma or a semi-colon. The email address of the user currently logged in displays by default.
Overwrite Results
Select this check box to overwrite the existing output files, if any exist. If this check box is left clear, and an output file exists in the relevant folder, the status of the job displays a message informing you of the existence and name of the output file. The message is also written to the event log of the job.
Thin Tie Points
Select this check box to thin the number of tie points (TP) collected.
That is, sometimes TP collection can gather too many points on each image. The distribution of the points may also be too varied. By thinning the points, you can reduce the number collected and distribute the points more consistently. Computation time is also reduced, because the detection of points requires less effort.
Refine Tie Points
Select this check box to refine the tie points collected. If this check box is left clear, you must verify and, if necessary, manually refine the tie points.
TP Rejection Method
The method used to reject tie points (TP).
You can specify various values for this parameter, depending on the method selected.
TP Rejection Method Thresholds
The rejection threshold values for the value selected for the Rejection Method parameter.
RMS Error: rejection starts from the point with the largest residual error for any point, and then recalculates the math model and RMS error. If the RMS error is still above the specified thresholds, the point with the next highest residual is removed and so on, until the x-RMS and y-RMS errors are equal to or less than THRESH1 pixels or THRESH2 pixels.
For example, a value of 2,2 rejects points with the highest residuals until the x-RMS and y-RMS are both less than two pixels.
Standard Deviation: THRESH1 and THRESH2 represent the minimum standard deviation values of the x and y residuals to be rejected, respectively.
For example, a value of 2,1 rejects points that have a standard deviation higher than two of the resX mean, and rejects points that have a standard deviation higher than one of the resY mean.
Percentage: THRESH1 represents the percentage of the number of points to be rejected and THRESH2 represents the ratio weighing between the x and y residuals. For example, if you set a rejection weight of 2, you are giving twice the weight to the x-residual (resX) as to the y-residual (resY). By default, the residual in x and y have the same weight. Therefore, if you have a point with a resX of 0.4 and a resY of 0.5, the point is given a resX of 0.8 and a resY of 0.5 for the rejection.
For example, a value of 5, 2 rejects five percent of TPs, and gives the x-residual (resX) twice the weight as that of the y-residual (resY).
Absolute Distance: THRESH1 and THRESH2 represent the minimum absolute x and y pixel residuals to be rejected. The rejection starts from the point with the largest x or y residual distance.
For example, a value of 2,2 rejects points with a resX of greater than two pixels, and rejects points with a resY of greater than two pixels.
Absolute Number: THRESH1 represents the number of points to be rejected and THRESH2 represents the ratio weighing between the x and y residuals. For example, if you set a rejection weight of 2, you are giving twice the weight to the x-residual (resX) as to the y-residual (resY). By default, the residual in x and y have the same weight. Therefore, if you have a point with a resX of 0.4 and a resY of 0.5, the point is given a resX of 0.8 and a resY of 0.5 for the rejection.
For example, a value of 10, 0.5 rejects 10 TPs, and gives the x-residual (resX) half the weight of the y-residual (resY).
Rejection Limit Percentage
The maximum percentage of the initial number of TPs to eliminate per refinement iteration.
Rejection Action
Select whether to remove or deactivate tie points (TP) rejected during thinning and refinement.

Preprocessing requirements
Before running this module, the following requirements must be met to ensure the job processes successfully and produces accurate results:
Input Project: The OrthoEngine project you specify as input must contain tie points (TP).
The Tie-Point Refinement ADS module reads the input project file, and then refines all of the TPs the file contains.
