Depth Display: is where how to configure the DPT NavData's range display, either choose under Sea
Level or under Keel. For example the depth measured Under Sea level is 100m and the keel Draft is
fixed to 8.0m. When you switch the Depth Display from Under Sea Level to Under Keel, the DPT
NavData's Range also changes and DPT will be be refreshed to 92m. Be careful if the depth and the
keel Draft information are both included in the NMEA sentence, the DPT range will also take in account
this difference.
Transducer Draft : enter the transducer distance below water. In the DPT NavData This information
will not be taken in account if this information is directly received from the NMEA signal.
Longitudinal Transducer Position : enter the longitudinal distance depending on your own ship pos
(positive value).
Lateral Transducer Position (-port): enter the lateral distance depending on your own ship
position.
Importing & Exporting 3D data
(Exclusively included in MaxSea Explorer)
The
"Import/Export" option available under the MaxSea Button will allow you to Import or
Export files where 3D data are stored.
MaxSea TimeZero can Import information from various files format:
PTF (MaxSea v12 layers Format) is a previous MaxSea v12 User's data layers file format.
XYZ (MaxSea v12 PBG Export)
PTZ (MaxSea v12 PBG database) note that the 3D vector chart points contained in the PTZ
file will not be imported. The same data can be found in the mm3D vector chart data (dbt
file).
Olex Depth Database Export.
BTH - Nobeltec.
Note : Before importing please check beforehand that the v12 database doesn’t contain erroneous PBG
(Personal Bathymetric Data) or the 3DDB.PTZ database is not corrupted, even partially. Once the database
is clean, you can import it into MaxSea TimeZero.
Select the type of data you wish to import :
1. Check the corresponding radio button and click on Next.
2. Click on "select the files to import" to explore your hard disk and choose the file to import.
3. Select Import Filters
If "PTZ - MaxSea v12 PBG database" option has been chosen, select “Remove
points out of range” option to avoid importing data outside the Minimum/Maximum
depth range (depending on the fishing area), then check the “Remove points using
statistical analysis...” option to automatically detect and remove inconsistent data.
Imported PTZ without applying any filters:
Same file imported with the “Remove points using
statistical analysis…” Option:
