Analysis on Land Use Dynamic Change Based on ENVI
2011
Remote sensing satellite image data of two periods were used,and ENVI software was used to carry out supervised classification,land use database of different periods were extracted,comparison method was used to comparatively analyze the classification results,thus,the dynamic changes data of two-period land use were obtained.Meanwhile,based on the related investigation information data collected by building interpretation symbols and man-machine interactive interpretation was used to obtain land use database in different periods.Then take this result as the reference,the obtained dynamic change data was verified.
