I am trying to take several dem sources and merge them together using VRTs, then I am using rio rgbify to make terrainrgb tiles The script I am using looks like https://github.com/acalcutt/terrain_merged/blob/main/create_terrainrgb.sh
Basically, I am trying to layer 3 sources -JAXA (full planet but lower quality) -TINITALY (slightly better quality) -SWISSALTI (best quality) Then using the ordering of the filelist into a final VRT to layer them in the correct order However when I try this, the layering seems to work, but I end up with lots of added lines, like this example https://stackblitz.com/edit/web-platform-wrcpum?file=index.html Can anyone suggest how I might fix these lines when combining these different source files? I have tested different resampling methods but it doesn't seem to be related to that. When I do the sources individually, I don't have those lines (see this example which is just jaxa https://stackblitz.com/edit/web-platform-al1zf5?file=index.html ) Note: This relates to a question in one of my own repos that I am looking into https://github.com/acalcutt/jaxa_AW3D30_to_MBTiles/issues/3 .
