I am using QGIS 2.18.11 with the Semi - Automatic Classification Plugin (SCP). I use Sentinel 2a as well as Landsat 8 Scenes and run some Classifications with SCP.
Inside my Sentinel 2a scene I have several areas I want to analyse. Therefore I want to clip the (classification)raster by a vector (I created upfront). This works perfect with "clip multiple rasters" by using the vector ... BUT: I need just the pixels inside the vector boundaries which do not have contact with this vector boundary.
I tried an option but it does not succeed:
I transformed the clipped classification raster to vector and clipped the two vector data (boundary and the tranformed classifiaction raster). That worked.
Then I tried to transform this new vector to a raster and hoped that there will be no pixels lying on the boundary but I just get my old classification raster back.
Any comments or suggestions?
This looks like as it should be
