I have mosaic several DEMs to a raster but I have encountered a problem whereby the output raster produces an image where one portion has additional black layer on it. I have attached the image in this post.

Please help. I have spend a lot of time trying to solve this. As I am very new to this software, I would really appreciate if anyone could give me a step-by-step guidance with this.

Many thanks in advance.
