Status flags are assigned to soundings during conversion, as determined from information provided by the specific acquisition format. When a Lidar sounding is converted into HIPS, it is given the following quality flags. These flags can be changed during processing.
This table shows the quality statuses that can be attached to a sounding.
Quality Flag | Description |
|---|---|
0 | The sounding has a detected depth only. The alternative depth is invalid. |
1 | The sounding has both a detected and a valid alternative depth. A quality control/assurance decision has not yet been made. |
2 | The sounding has a detected depth and a valid alternative depth, and the user has decided to keep the detected depth. |
3 | The sounding has both a detected and alternative value, but the alternative value has been swapped with the detected value). |
Selecting Detected and Alternative Data
In some instances, two depth values (detected and alternative) are returned. You can decide which depth value is most relevant and change the sounding's quality flag accordingly. This can be done in either the Swath Editor or the Subset Editor.
Soundings are highlighted in the colour that is set in the Tools > Options > Display > Editors > Lidar dialog box.
