Supported Data types?

I'm new to the Bathymetry extension and am trying to add data into a BIS.  I'm only seing .bag files as the option for adding data.  I have a lot of multibeam data that exists in ESRI grid format.  Is there a way to add these files?

Hello,

We are currently working on enabling the Bathymetry extension to support for all the gridded formats recognized by ArcGIS, including Esri Grid. In the meantime, the data has to be in the BAG format.

Thank you,

Bertrand

Good morning,

we have a potential customer that has acquired with his system a huge quantity of XYZ data for bathymetry.
Does the future release will be able to import and process this kind of data?
Any news concerning this new release?

Thanks a lot,

Hi Enrico,

I work for the ArcGIS for Maritime: Bathymetry solution team. We do have plans to support XYZ data in the near future. Could you please provide more details on what format this data is in? Is it just raw coordinates or is it in a specific format? If you could provide more details, we could look into it further when we begin working on supporting points data.

Thanks,

Hi Sebashan,

unfortunately I haven't had access to raw data, nor to speak directly with interested people.
Only thing that I know yet is that they use a Eiva Navi Pack Survey and the QPS Qinsy system, and have imported the output data in XYZ file format in ArcGIS desktop.

If more info are available I'll update this thread.

Hi Enrico,

Because you mentioned the XYZ data is raw, I'm curious to know what the customer plans on doing with this data in ArcGIS. If this data is unprocessed, they may need to first "clean" it in Fledermaus. Even if it is processed data, they may need to select soundings in Fledermaus to reduce the point density before they bring it into ArcGIS. Fledermaus also allows export of points as BAG (Bathymetry Attributed Grid) files which they may bring directly into the ArcGIS for Maritime: Bathymetry solution.

Thanks,

Sabeshan

Enrico,
I also recommend educating the customer regarding International Hydrographic Organization (IHO) S-102 standard for bathymetric data.  This is what is commonly called "BAG".  The definition is carried through from the open source initiative documented in this 2005 paper (http://www.thsoa.org/hy05/05_4.pdf) and referenced at University of New Hampshire's Center for Coastal & Ocean Mapping, available at the website: http://ccom.unh.edu/theme/data-processing/nav-surface-and-bags

The actual Open Navigation Surface site is: http://www.opennavsurf.org/ and the standard S-102 is documented here: http://www.iho.int/iho_pubs/standard/S-102/S-102_Ed1.0.0_Apr12.pdf

Please note that the S-102 standard, when used with proper metadata, is the best way to manage bathymetry as it provides estimate of error to be stored in the grid as well as the value of the depth.  Esri's solution goes further in that the extensible metadata for each BAG can be used to formulate composite bathymetry from multiple BAG files without duplicating the underlying depth information.  In other words, copying the large XYZ files is not necessary.

Guy

Sabeshan and Guy,

thank you very much for the inputs and links.
Very useful to "educate the customer" (like this sentence) and better know this domain.

Regards,

Enrico
