The procedure went well. Image 1 represents the raster (Chelsa) of annual mean temperature (bio1). I clipped it using a shapefile of country boundaries and the resulting image is image 2. As you can see, there is a contrast difference between the layers and the legend values on the right also changed. If I use this clipped raster for my further analysis, will it have any adverse impact on the results. I have been behind this for quite sometime but Not Yet Resolved.
Response to @rumski20
- Downloaded .tif files from Chelsa (Image 1),
- Converted them into .asc files in QGIS 3.18 using Translate option. While translation, no data values were not given.
- Translated ASC files were clipped using shapefile while clipping No Data Values were assigned. No data values were sourced from the developer (Image 2).
