Exporting to PPF Format
Station Extraction
The operator has the option to export only certain sections of the data, based on the stationing set
within the profiling data. To use this feature, select the check box near “Specify Station Numbers.”
When the box is selected, the operator will be able to adjust the stationing numbers. The ‘Start’
stationing is the initial stationing where the exported file will begin, while the ‘End’ stationing is the
point where the exported file will finish. These values can be adjusted by typing values into the box
or by using the arrow keys to the right of the box.
Filter Settings—High & low pass length
The exported data file can have an additional filter applied while being processed into the chosen
format. To not filter the data, leave the filter lengths at the default value of 0.00.
High Pass Filter
–
The High Pass Filter will remove any trend in the data that is less that the
chosen length. The length can be selected by typing the value in the box or by using the arrows
to adjust the input.
Low Pass Filter
–
The Low Pass Filter will remove any trend in the data that is greater than the
chosen length. The length can be selected by typing the value in the box or by using the arrows
to adjust the input.
