EM2042 support and new KMALL datagram revision

[monocilindro]

Kongsberg has launched their new MBES for shallow water, the EM 2042. Could you Kluster support it? I am attaching a sample zipped file .
There is also the just released Kmall rev J (https://www.kongsbergdiscovery.online/sis/kmall/html/index.html) . although that EM2042 file was logged with the previous datagram revision.

I expect we could support the new format but I can't give a timeframe at the moment. We were understaffed for a good while and just hired some new people but will take some time to get through our backlog.

@monocilindro I don't see the sample file, are you able to share a link here? Or attach it?

Hi Eric, It is good having you back here!
Please find some sample files in these links :

@monocilindro Hi Jose! Thanks, happy to help. I think that link no longer works, did it expire?

[monocilindro]

Could you provide an email address? It think it is best to send you the files there

Looks like this might be non-trivial. I added support for the 2042 which wasn't difficult, but these files you sent me have an installation parameters record with extra fields that I don't remember seeing, and an SPD datagram that isn't supported by our driver. We'd need to investigate both of those things. I'm guessing that while this might not be the latest file version, it has enough new stuff to cause issues with Kluster/Pydro.

You can replicate my test by going to "tools - file analyzer" in Kluster and printing out the first 50 records.

I'm happy to handle the little things to keep this project alive, but I don't really have the time to dedicate to updating for the latest stuff. Especially since I know that there is always an avalanche of new stuff in hydro!

Kluster v1.1.6 will have the 2042 support at least. Available on the master branch. Working on building an executable now.

The SPD datagram is meant to build a DTM in real time. It seems that Kluster won't use it since you do all the raw calculations and raytracing to get the soundings.
It is documented here https://www.kongsbergdiscovery.online/sis/kmall/html/structEMdgmSPD__def.html

Kluster 1.17 does not process EM2042 files . I am sending you some sample files. just in case you can find sometime for it, eventually
