These are sub-sea survey systems. The sonars are mounted
on ROVs, and data are logged top-side. From one section
of sea floor hase been finished surveyed, we have 24 hrs
to process the data and hand over first-stage products,
like shaded relief images of the sea floor, and certain
other specifics, to the client's representatives.

For all practical purposes, we do a full processing
within those 24 hrs. The stage 2 products are merely
re-plotting of the same data, and merging several
sections of data into one presentation.
