What file formats can II&T read?
This question has two aspects: physical format, and logical format. We can read: 8 mm tape (8200 or 8500 format, including XL), DLT tape (I, II, III, or IV), and CD-ROM (ISO9660 with Rock Ridge extensions. Note that neither Apple nor Microsoft adheres to these standards, but we can probably read your CD-ROM anyway). Logical formats are more complicated. For seismic data, we can read genuine SEG-Y format from tape, and most tape images on disk, or tar tapes of disk images. We cannot read SEG-A, SEG-B, SEG-C, SEG-D or SEG-X. We probably cannot read “SEG-Y” data with ASCII headers instead of EBCDIC, or with a header other than 3200 bytes, or with trace data in some strange floating point format, or with no values anywhere in the binary header. We cannot read 3D seismic data from a SEG-Y file if we have no clue as to the geometry of the 3D grid (actually, we can, but you probably don’t want to pay for the time it takes to do this). Navigation data can be read from any ASCII (or EBCDIC — b
