Sir, I have a doubt regarding using Landsat data. Do we not need to project the images from Landsat 8 data? In one of your videos while creating a shape file and defining its coördinate system you chose same as composite. So do we need to project Landsat data?

[@vikasghadamode]

@@PoojaSudheer-j1s No need to Project Landsat imagery, Because they are already projected, you can check projection in Source

Sir I want to know how to delete that unwanted water bodies which are not accurately classified. Which function I have to use?

[@vikasghadamode]

@@ankitashinde3228 You need to convert water bodies file from Raster to vector, after it converts to vector you can delete unwanted water bodies area
