Qimera Re-Nav Z Process

Qimera - Re-Nav Z

This process will be initiated automatically by the Dynamic Workflow engine whenever the primary source of height information has been changed via one of the following methods:

• Height time series editing - here
• Height time series import (i.e. POSPac, SBTC, or tide) - here or here
• Height time series source re-prioritization or height configuration - here

This can easily be demonstrated by the following example, referenced to the image below. Using 4 lines, (2 outbound and 2 inbound that have a time separation of ~5 hours) you can see an obvious tide bust where they overlap (see below).  If we import just the GNSS height component of a POSPac file, Qimera will Re-Nav the lines and update the dynamic surface.

Original Lines

Dynamic Workflow Prompt

Once the GNSS height data is imported, Qimera's Dynamic Workflow engine prompts the user what needs to be done.  If you check Don't Ask Again before clicking on Yes, Qimera will automatically perform this task in the future.  Once you click Yes, the Job Activity window will display the running task.  If you click No, Qimera will wait for you to later click on the Auto Solve button.  You don't have to remember which type of operation needs to be performed on the file, because the operations all have a precedence.  So if you change something for this line that requires full sound velocity correction, this job will not be doubly performed.  The Dynamic Workflow engine takes care of this for you.

Update Dynamic Surface

Once the Re-Nav Z process is complete, the Dynamic Surface is automatically updated.  No further action is required.  The updated surface is shown below.
