In this tutorial, we would learn how to perform spatiotemporal analysis with the help of two Landsat images. Images are classified into four classes: Buildup, Water, Vegetation and Barren Land. Through MOLUSCE Tool predicted map can be prepared of the Land use based on Artificial Neural Network. #QGIS #Remotesensing

@gisrssol.6851
@gisrssol.6851 Год назад
Sometimes even if we give same coordinates to raster images still there is an issue of a spatial extent. I would recommend you should convert your shapefiles and extent with similar properties by converting it from some online websites. That would be helpful more and the geometrics issues will be resolved.

Sometimes there are some outliers which need to be identified so to increase accuracy . I would recommend to find those outliers by seeing the spectral differences in ENVI software if possible.
