QPD

QPD items are only available for Export and not for Display, Driver nor Log File

Note

It is recommended to set the Export Mode to Ping based in order to export all DTM QPD data:

Note

More information about the Export Generic Wizard can be found here.


Parent Item
Source:
  • Default QPD (default)
    The QPD file that has the same filename as the selected database will be automatically used.
    Most useful when option 'Use Database storage name' is used in the online Session Setup:


    When there are two matching QPD files, one accepted by the Survey Manager and one not, then the not accepted one will be used.
  • [ Browse... ]
    The user must browse and select an existing QPD file.
Filename:

Use the button to browse for a QPD file. The filename will be displayed in red when the (last) selected file is not found.

This option is only visible when the source is not the Default QPD.

Transducer:Select from the list with all possible transducers being used the one that should deliver the ping and footprint data.
Reference:
  • Raw
    Original QPD data from an online recording or a replay session will be used.
  • Validated (default)
    Filtered QPD data (e.g validated using Qimera or the Validator) will be used.
Point Ids:
  • NONE, or leave <Empty>
    None of the selected 'Point' sub items will be used.
  • ALL
    The selected sub items will be repeated for all available points (or beams) for the current ping
  • CENTER
    The center DTM point will be used for the selected 'Point' sub items.
    Formula used to calculate the center point number is: (Number of Points + 1) divided by 2.
    When your selected Transducer is the Detected Pipe, the Top of Pipe will be used.
  • Enter individual point id number, and/or comma and/or hyphen (or double-dot) separated.
    For example: "20-230" or "1,5,10,20-30" or "1-10,120,230-240", or "60..70, 80..90".
    Lowest possible point number is 1. The selected sub items will be repeated for each defined beam number
  • When your selected Transducer is the Detected Pipe, you should use the following Id:
    • 0: Seabed Left, 1: Trench Left, 2: Top of Pipe, 3: Trench Right, 4: Seabed Right.
      More convenient is to use:
    • TP for Top of Pipe
    • SL for Seabed Left, SR for Seabed Right
    • TL for Trench Left, TR for Trench Right
