Read Travel Time file (SEG-Y)
S-01430
As a Tullow Geophysicist I want to be able to read my Travel Time (TT) file in parallel by calling a simple API. I want each node to be able to specify a specific 3d volume to read in the file and the portion of that volume to read. I want these reads to be done in a manner which provides maximum efficiency.
The SEG-Y file stores one 3d scalar grid per source/receiver grid coordinate. This is a 5d grid. This is stored as a series of traces. The elements within a TT "trace" correspond to increasing depth for fixed inline,crossline. The order of the traces indicates the source/receiver inline, source/receiver crossline, inline of TT element, crossline of TT element, with the quantities that vary most quickly being the reverse order. The various coordinate increments are separate from each other. These files are usually well structured and ordered.
I want this ability because the TT data is required in the KDMig calculations.
