Q: How can I build an Online DTM in Helmsman's Display?
A: In Helmsman's display under the Online node in the Project tree, after the connection to NaviScan has been established via the connect button from the Main toolbar, you will find all the instruments (positioning, gyro, mbes etc) availble. Right Click on the mbes instrument and select Build Online DTM.
A window will appear on the screen asking to define the name, resolution and other settings of the DTM.
The DTM will appear under the Surveys in the Project Tree.
The DTM has the option to be created only when logging(True) or always (False). This option is present under the properties of the mbes instrument in the Online DTM section.
If you have a dual head setup and you want to create a DTM for the both heads you must select the second head, go to the properties of the instrument in the Online DTM section and press on the Online DTM to define the previously created DTM for the first head where the data will be gridded.
Now both mbes heads insert the data to the same Online DTM.
