Qimera Add Tide File Dialog

How to Start

What it Does

This dialog imports tide data used for tide corrections and assigns the data to a station for management.

General Description

The dialog has several sections, these are explained below.


After selecting a tide file the Format dropdown will be populated with any Tide Formats that match the file in addition to a Custom ASCII option. If the file format is not supported the default is Custom ASCII.


The Configure button is currently only enabled for Custom ASCII format. Clicking it opens the Custom ASCII File Configuration dialog. Be sure to map appropriate fields for both Time and Tide.


Tide files must be assigned to a station. If there are existing stations the drop down will be blank and a station must be added. If files have already been added to the project the drop down will be populated with the existing stations, and the best match based on metadata in the file will be selected by default.

Add Station

Click Add Station will open the New Tide Station Dialog. If there is any metadata in the tide file those fields will be automatically filled.

Tide Type

The tide type allows for tides of different priority to be imported for the same time period.

The three types in increasing priority are Predicted, Observed, and Verified. The highest priority tide type that is available at any given time will be applied to raw sonar files when processed with vertical referencing set to Tide mode (see Processing Settings Dialog for more information).

Property Comparison

The property comparison is for reviewing the station details to see if the agree with the file's metadata.

Use as primary source for applicable files

When checked this option will make the imported files take the highest priority in the Processing Settings Dialog and switch the Vertical Referencing Method to Tide.
