The presentation made to Wits Statistics Department was on common classification methods used in the field of remote sensing, and the use of remote sensing to design optimal sampling schemes for field visits with applications in vegetation and geology. For vegetation the sample was designed to give more accurate measures of vegetation indices and for geology the sampling was designed to target alunite.
