Trimming GPR Data

In this video we are going to see how to perform the trim data filter. The trim data filter can be used to discard data from a starting sample until the end of the time window and thus keep data only up to a certain time. First let’s change the y axis to samples. Then go to the process tab in the right panel and click on the plus symbol. From here, select trim data and set the starting sample. We will set it to two hundred and click on the apply button. In order to visualize the trimmed data select the trim data filter from the list at the bottom of a B-scan. On the top window you can see the raw data, whereas at the bottom you can see that the B-scan has been cropped.
