Analysing (2D SEG-Y)

The next step is where the SEG-Y Loader uses the header mappings to analyse the SEG-Y data and detect problems. For loading 2D data, this step will discover the CMP values in the data, the shape and geographical location of the data (if calculating tie points from X/Y headers), and any invalid data.

Analyse the trace headers

Analyse the trace headers
  1. In the Analysis pane, click Start. The SEG-Y Loader will process the data line by line, first applying the filters (from the previous step in the wizard), then analysing the CMP, X, and Y headers. At this stage, the SEG-Y Loader will analyse the entire dataset.
  2. Warnings may be displayed at the bottom of the page during analysis. If you find that your header mappings are incorrect, click Back to return to the Specify the byte locations of headers window. You should go through the analysis results to ensure everything is as expected.
  3. If no errors are reported, click Next to move to the next step.
