Module name                Read Seismic Traces

 

Read Seismic Traces module is used to read any dataset (internal *.gsd) generated by g-Platform™. Similar to "Read SEG-Y traces" module, here also the user should input the dataset from the Parameters tab.

 

When the user clicks at Seismic file name it will be blank as shown below under Value column. Once we click, it will display all the available internally generated dataset(s).

If we observe the right hand side image, we see two datasets with the dataset name, survey description, from which workflow we generated this dataset. The background color (blue) coding tells us that the datasets are generated in this project. If the background color is different that means either we imported those datasets into the current survey/project or they are not related to this survey/project.

 

Just select any one among them and hit Enter. We just input the dataset to the "Read seismic trace" module.

 

Parameters        

Enable active location map

By default it is unchecked. If user checks this option, it allows the user to click on the location map to display the current source/receiver/bin gathers.

Show header ranges

This will display all the trace header ranges.

Find ranges of trace headers

By default it is unchecked. If the user checks this option, it will display all the trace headers range. It will work in conjunction with Show header ranges option. To see the trace header ranges, the user should go to Information tab and look for the Trace headers option which is at the bottom.
