    What is the point of creating a virtual raster when you have to clip the roi using the raw images ? and after i clipped by boundary file with the virtual raster i put training outputs using the clipped image of virtual raster but after processing the classification it gave the result of entire tile instead of just roi. Do we need to change input while classifification or do anything to give classification only of roi? please clear the the doubt because i am confused whether the result is right and just need to clip boundary file again or is there any setting to classify only on roi

      You can clip all the bands and then create a composite to train your samples. or you can classify the entire satellite image and after that clip with your roi

    I tried to do this recently but in newer version of scp, its not showing the virtual raster. I even updated qgis to latest stable version 'Prizren'...Is it total different process in updated plugin?

      Virtual Raster option is available in the SCP tool (at the bottom).
      Otherwise go to Raster > Miscellaneous > Create Virtual Raster

      I tick that 'create virtual raster' option still didn't work.
      And when i tried to do the colour composite an error occurred saying "No such file directory"

      Go to SCP Band set
      click on '+' sign at the right

      Check create Virtual raster
      Set satellite according to your satellite image

      A sound will come for generating virtual raster image.
      If virtual raster layer doesn't appear on your canvas then add the virtual raster from that folder and change the symbology.

    after clipping i couldn't find the "LANDSAT" option. i tried using image conversion but when i use the clip and its metadata it still doesnt work

    • @dawnofgeospatialworld

      In the latest version of SCP, LANDSAT tool has been removed.
      You can do that step manually. Check the 1st step from this video: ua-cam.com/video/g_m_Q6YQCs8/v-deo.htmlsi=gW5VX3PwRI6yxYxl

      You can make a composite of all bands by layer stacking method, then clip out your study area. Then take sample location polygons & classify the image

      Take samples for each clases and classify. It will classify your satellite image according to your sample classes.

      @@АнжелаМедведева-о1н OK, you want to know about conversion to TOA process. Yes, in the latest version of SCP, LANDSAT option has removed. But you can manually convert the satellite images to TOA by Raster Calculator for each bands separately. For that you need the metadata file of that satellite image.
