I am trying to mosaic 19 rasters which i already reprojected in WGS 1984 World Mercator and then hillshading them. These are the steps i follow please correct me if i am doing something wrong.
I am am using the mosaic to new raster tool , i have been referring to this question Mosaic to New Raster tool fail so i am not creating the raster dataset in the same location where the rasters are stored (used Desktop in this case). I made sure that the pixel type and the number of bands are the same.
The result is acceptable.
Here comes the problem. Now i hillshade this raster. At first look appears to be ok but when i zoom in as you can see in the image below the hillshade comes with some grid like lines. I don´t understand what am i doing wrong.
