Option #1 - Filter your data

Use the filtering utility to filter unwanted or out-of-range data from your raw data files by supplying a range of valid values for the different data types. It is recommended to use this function to remove peaks and zero's from your sounding data before you edit the sounding using the echogram editor.


Option #2 - Edit echogram(s)

The echogram editor allows you to remove spikes, null soundings and other errors directly from the echogram. All you have to do is select the invalid data and click the "remove selection" button.


Option #3 - Edit position data

The position editor can be used to remove invalid (GNSS) position fixes from the raw data. You can also use this tool to remove any data which is outside of a predefined boundary.


Option #4 - Other tools

By clicking the "Tools..." button, a second screen is displayed with a collection of miscellaneous tools, including: device latency correction, time correction, coordinate system re-projection, unit conversion, manual editing, PPK processing and offsets.
