By default, Kongsberg ALL files are converted to QPD format on import. The QPD format is used to store computed footprints and is the QPS format for processed point data. The newer format .kmall will not be automatically converted.
IMPORTING ALL & KMALL FILES
- Once you have created your project either use the Add Raw Sonar Files prompt, the equivalent icon
- You can either select the option to Add Files or to Add Directory - please be aware if you have multiple vessels that it is only possible to add one vessel at a time.
- The .all and .kmall files provides most of the information required by Qimera, the only thing that needs to be set manually is the co-ordinate system. The default is WGS_84 which is normally correct.
The vessel name for .all files is sometimes stored here, if it has been setup in SIS, if it has not been set then Qimera will combine the sonar model number and the serial number to create a unique name.
For the .KMALL file the vessel name is not stored as it was previously in the .ALL format. The sonar model number and serial number will be used as above for the .all.
Full sonar processing is not currently supported for some of the older Kongsberg systems. The systems that fall into this category are the EM1002, EM3000, EM300, and EM120. Data from these systems can be imported in Qimera using the 'Add Raw Sonar Files' dialog but processing is limited to applying SBETs, Navigation, and Tides. Point cleaning, including use of the Swath Editor, and creation of surfaces is all possible.
- The vessel offsets for all sensors is stored in the .all and .KMALL formats, as such Qimera reads these and uses them appropriately during all processing so no further vessel configuration is needed.
Working with Kongsberg ALL Data
The Qimera Quickstart was written based on Kongsberg ALL data and provides step-by-step directions and sample data for this format.
We suggest using that page as a guide for working with Kongsberg data.
