Storage - DTM File

Format

Select one of the supported formats from the pull-down menu:

• *.qpd - QINSy Processing - This is the recommended format, a proprietary format which can be imported into the Validator, QLOUD or Fledermaus for further processing, analyzing and/or publishing.
  Select how to treat flagged footprint data on the line 'Flagged FP' below.
  This format is not available when replaying recorded databases in batch in combination with the file Mode set to User-defined name, due to the fact that *.qpd files can't be appended to.

• *.pts - ASCII Grid (East North Depth)  - See below for a description of this format.

• *.pts - ASCII Grid (Extended Format) - See below.

• *.pts - ASCII GEO (Lat, Lon, Depth)  - See below.

• *.pts - ASCII Grid (East North Height Intensity Quality) - Typically for storing laser scanning data, because this format allows access to the raw intensity value as reported by the laser scanner. See below.
  Note that a *.qpd file only contains the quality value, which is a normalized intensity.

• *.pro - QINSy Mapping - Terramodel format.
  This format is not available when Split Method is set to DTM File Size, which is a setting under Session Setup-Storage-Control.

• *.fau - Binary FAU - A special format for clients mostly working in Scandinavia.

• *.mbes - Binary WSV - A special format for clients working in Germany.

Mode

The mode determines the name of the storage file:
Use Database storage name - By Default and Recommended. The DTM file will have the same storage name as the raw data file.
This is highly recommended, since some processing tools require a DTM file to have the same name as the corresponding database.
User-defined name - User is able to enter a different file name. This is not recommended.

Flagged FP
(foot print)

If you chose Format '*.qpd - QINSy Processing' this extra line appears where you can select from three options:

• All footprints are stored, flagged footprints are inactive (Recommended) - The most used option. Data that did not pass the online filters has been flagged, but not deleted. So during processing the flagged data can be easily restored if needed.

• All footprints are stored, all footprints are active - Normal, full QPD.

• Flagged footprints are not stored - Reduced QPD. The file is of the same QPD format as both options above, but does not contain footprints that have been flagged by the online filters.
  The main benefit will be the smaller file size of the *.qpd files.
  However, if you need to restore flagged data you will need to completely replay the database and create a new *.qpd file with different online filter settings.
  This format is not available when replaying recorded databases in batch in combination with the file Mode set to User-defined name, due to the fact that *.qpd files can't be appended to.

Use System

Activate the echosounder system(s) that should be used for the generation of the DTM file.
If you have two echosounder systems, and you do not want to have data from both systems together in one DTM file, you can replay the database twice.
Make sure to enable only one system and change the name of the DTM file the second replay time.

Layer name

This setting is only available when File Format is set to '*.pro - QINSy Mapping'.
A Terramodel file is a layer-based file format, so you may enter here the name of the layer in which the DTM data should be stored.
If the layer does not exist, it will be created automatically.
Note that you can not append to an existing *.pro file.
