Using the Tie-Point Collection and Refinement module

You collect and refine tie points (TP) by running the Tie-Point Collection and Refinement module.

To run the Tie-Point Collection and Refinement module

On the JPS Administrator Navigation bar, click Create Job.
In the list of jobs, click Tie-Point Collection and Refinement.
The Tie-Point Collection and Refinement page appears.
Type information or select an option for each parameter, as necessary.
For more information on each parameter, see Tie-Point Collection and Refinement module.

Module details

The Tie-Point Collection and Refinement module reads the Input Scenes folder for valid imagery files or a valid OrthoEngine project file (oe.prj). Depending on the number of input scenes, the module creates one or more jobs to collect the TPs, each processing a subset of the input scenes. The module creates a separate OrthoEngine project for each subset (child job), which stores all collected TPs for the images in the given subset.

When all of the TP-collection jobs are complete, the module merges all the subset projects into a single one. The collected TPs are refined to meet the specified accuracy requirements, and a report summarizing the accuracy is created. A final OrthoEngine project file is created with the refined points and updated math model.

Note: When panchromatic data exists in the Input Scenes folder, TPs are collected only on the panchromatic data. The other scene types (MS, PSH, SAR) are copied to the output folder.
