Historical Search Planning Tools
Prior to SAROPS, SAR controllers in the U.S. Coast Guard used the Computer Assisted Search Planning (CASP) and Joint Automated Work Sheets (JAWS), which used dated search planning techniques and algorithms. More specifically, CASP was based on old computing technology and JAWS was taken directly from pen and pencil techniques for shorter durations of drift in coastal environments. Environmental data consisted of low-resolution (1-degree latitude/longitude grid) wind and current information that was applied every 12 hours. For most areas, CASP used monthly-averaged current values while JAWS used one wind and current value during the SAR case. Neither system was capable of accessing timely high-resolution wind nor current model output, which was a significant disadvantage since one of the main components that determine the accuracy of the drift solution is the presence of precise and accurate wind and current information for the given area of interest.

Famous quotes containing the words historical, search, planning and/or tools:
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
“So often has my judgment deceived me in my life, that I always suspect it, right or wrong,—at least I am seldom hot upon cold subjects. For all this, I reverence truth as much as any body; and ... if a man will but take me by the hand, and go quietly and search for it ... I’ll go to the world’s end with him:MBut I hate disputes.”
—Laurence Sterne (1713–1768)
“When we are planning for posterity, we ought to remember that virtue is not hereditary.”
—Thomas Paine (1737–1809)
“Think of the tools in a tool-box: there is a hammer, pliers, a saw, a screwdriver, a rule, a glue-pot, nails and screws.—The function of words are as diverse as the functions of these objects.”
—Ludwig Wittgenstein (1889–1951)
