FMMidwater is a software program designed to rapidly extract relevant water column features from a range of sonar file formats. Raw sonar files are first converted to a Generic Water Column format (GWC) for use in further processing and visualization. A simple graphical user interface is used to perform threshold filtering on a number of key parameters to help with feature extraction. FMMidwater also provides multiple views of the water column features and finally allows for easy export to a variety of Fledermaus visualization objects and text files.060371
FMMidwater Supported Data FormatsFMMidwater supports a range of file formats that contain water column time-series data from either single beam or multibeam systems. Ancillary file types can also be loaded to aid in processing. Currently supported sonar file types are is listed below.QPS (.db/.qpd) Files – Support for Kongsberg, Reson and R2Sonic sonars that log water column data in QINSy is available via opening aQINSy project. The .db files provide the raw water column datagrams and the .qpd files provide the navigation and orientation of the sonarhead for each water column ping. These are combined to create a GWC.Kongsberg (.all) Files – Support for .all files containing datagram 0x6B. Example sonars logging this file type include the EM 122, EM 302, EM 710, EM 2040, EM 3002 and ME 70.Kongsberg (.wcd) Files – Support for .wcd files containing datagram 0x6B. Depending on the settings of the operators topside logging software (SIS), water column data can be logged to a separate file type while all other packets are logged to a .all file. If the .wcd file lacks navigation and system configuration information, the user needs to additionally load the matching .all file which contains required system configuration and navigation data. This type of processing is explained in more detail in section 1.7.3.1. Example sonar types are the same as the .all format.Kongsberg (.kmall) Files – Support for .kmall files containing #MWC datagrams.Kongsberg (.kmwcd) Files – Support for .kmwcd files containing #MWC datagrams. Depending on the settings of the operators topside logging software (SIS), water column data can be logged to a separate file type while all other packets are logged to a .kmall file. If the . kmwcd file lacks navigation and system configuration information, the user needs to additionally load the matching .kmall file which contains required system configuration and navigation data.Kongsberg / Simrad (.raw) Files – Support for .raw files containing datagram ‘RAW0’ datagram. Example sonars logging this file type include the ME 70, EK 60, and ER 60. Support for .raw files containing ‘RAW3′ datagram in narrow band mode only. This includes EK 60 recorded with new Kongsberg topside software as well as EK 80 recorded in narrow band. EK 80 wideband mode is not yet supported natively.Kongsberg / Simrad (.ek5) Files – Support for .ek5 files containing datagram 0x3356 (VolumeBS_1), 0x3256 (VolumeBS_2) and 0x3356 (VolumeBS_3). Example sonars logging this type include the EK 500.Imagenex Delta-T (.83b) Files – Support for .83b files containing datagram ’83b’ (Beam Output).Reson (.s7k) Files – Support for .s7k files containing datagram 7008, 7018 or 7042. Example sonars include 7125 and 7101. As of FMMidwater v7.7.0, the compressed water column packet is supported as well (datagram ID 7042).SEGY (.seg, .sgy, .segy) Files – Support for SEGY files containing trace datagram. Example sonars logging this type include EdgeTech Chirp systems. Typically, sub-bottom time-series data contains part of the water column prior to seabed penetration. FMMidwater simply treats the sub-bottom channel as a single beam echo sounder.DBM (.dbm) Files – DeBeers mining format.Triton Imaging (.xtf) Files – Support for .xtf files containing Sonar (type 0) datagram with sub-bottom channel.POSPac (sbet.out) Files* – POSPac data can be loaded as the navigation source during the GWC file creation or applied afterward as well. This is explained in more detail in FMMidwater Quick Start Guide.Generic Sensor Format (.gsf) Files – GSF files can be loaded as the navigation source during the GWC file creation or applied afterward as well. This is explained in more detail in FMMidwater Quick Start Guide。
