Supervised classification by using ArcGIS
Supervised classification technique was used to identify the land use land cover (LULC) changes by using different satellite images. Various satellite images were used like Landsat, MODIS and sentinel etc. First, the Landsat image must be composed because it comprised many bands. Layer stacking was fulfilled to get an image with band combination. The process of sub setting was conducted in Arc GIS 10.1 software by using the extract by mask tools of the image based on the study area. 2 nd , digital LULC classification through the supervised classification method (maximum likelihood algorithm), based on the field knowledge, was employed to perform the classification for different years. To make LULC maps, we have used supervised classification by taking care of the study area of interest as well as field survey measurements together for training and validation parts. These LULC images were then reclassified by using software Arc GIS to compare the changes found in these years. E...
