Soon you were fairly satisfied with your new inquiry.<br /><br />I think the same process might well be applied to the use of satellite imagery. Its not always a question of "where is she now" but "where was she then". <br /><br />Consider the RCCNZ: they started out with an erroneous Last Known Position due to an over reliance on Iridium's doubtful GPS information and an under reliance on Evi's stated position since she was a 73 year old female. Had they known at the time that she was a smart as a whip navigator they might have used a different start point. Then RCCNZ started their drift modeling software, but the question is WHAT do we model? A Bare Poled Nina making four knots, a bare poled Nina with increasing engine cooling problems, a capsized Nina, a capsized Nina with masts, a capsized Nina that is dismasted, a life raft with the weight of all persons aboard or a life raft with the weight of only one person aboard? On what days and at what times should the drift modeling software change from one assumed shape to another shape? When does wind and current become factors of diverging effect in modeling software? <br /><br />One of the more sensible ways to use satellite images might be to use historical images from June first and then keep track of where the Nina was in order to find out where she is. Once located on historical images, the Nina could be followed so as to determine precisely when and where she transitioned from yacht to dismasted yacht.So the search becomes a Where WAS the Nina rather than a Where IS the Nina? Then when the next pass of the satellite fails to reveal confirming information of the Track.... you know to start the life raft modeling software. <br /><br />Sure the P3 Orion flights giving current hyperspectral pixels would be interesting as would current data on simultaneous use of multispectral imaging of UV and IR images, but the primary use of satellites would be to follow the track of the needle rather than to find the current location of the needle.<br />FleaStiffhttps://www.blogger.com/profile/09837830811566745662noreply@blogger.com
