area－to －point 　cokrigin g　and　multiple －point 　geostatistical　simulation 　for remotely　sensed 　image　fusion

a　method　for 　remotel y　sensed 　image　fusion　was　developed　based　on　the 　theor y　of　multiple point 　geostatistics mpg．the　aim　was　to 　increase 　the 　spatial 　resolution　of 　the 　fused 　image　using mpg－based　simulation．a　spatial 　correlation　model　in 　the 　form　of 　a　trainin g　image　is 　incor porated 　insimulation and　then　a　pattern－based　decision　rule 　is 　applied 　to 　facilitate 　re production　of 　similar 　localpatterns 　in 　simulated 　images．area－to－point 　cokri gingatpckwas　used　as 　a　simulation 　constraintto 　solve 　the 　change－of－support 　problem．the　method　was　tested 　on　landsat　etm＋images．resultssuggest 　that　atpck－mpg　can　achieve 　a　more　accurate 　result 　than　simulations 　that 　do　not　account 　fordifferent 　data　supports．this　method　can　be　applied 　for 　conflation　of 　other 　types 　of 　spatial 　data　aswell．
