AB: The high volume of today's remotely sensed Earth Science data creates a strong motivation to minimize the amount of data delivered to the end user. The goal is to get users everything they need but nothing they don't need.ÿ One way to decrease the amount of unneeded data delivered is to increase spatial search accuracy.ÿ Unfortunately, the most voluminous data, orbital swath data, is also the most difficult to run spatial searches on.ÿ Three reasonably accurate means for spatially searching orbital swath data are: methods employing lookup tables, methods employing orbit propagators, and backtrack orbit searching. This poster outlines these three types of methods and discusses some of the advantages and disadvantages of each.
