This data structure is used to store multibeam bathymetry * and/or backscatter data with arbitrary numbers of beams. * This format was created by the Lamont-Doherty Earth * Observatory to serve as a general purpose archive format for * processed multibeam data. * 2. The data consist of variable length binary records encoded * entirely in 2-byte integers. * 3. Both the depth and backscatter arrays are centered. * 4. The kind value in the mbf_sbsiocen_struct indicates whether the * mbf_sbsiocen_data_struct structure holds data (kind = 1) or an * ascii comment record (kind = 0). */ /* maximum line length in characters */ #define MBSYS_LDEOIH_MAXLINE 200 struct mbsys_ldeoih_struct { /* type of data record */ int kind;
