How to combine outputs of more than one geotiff

[safa833]

I need to combine ctb-tile outputs of geotiffs, because lots of geotiffs take a long time to merge
How do I manage this ?
Thanks.

@ahuarte47 Thank you. It works. I solved the problem.
However, It works after some of ctb-tile parameters remove

1. ctb-tile -o terrain -f Mesh -g 1.1 merged.vrt
   unrecognized flag -g

2. ctb-tile -o terrain -f Mesh merged.vrt
   Error: Could not retrieve GDAL driver

3. ctb-tile -o terrain merged.vrt
   There is no problem, I obtained output as height-map but How can i get output as quantized-mesh

By the way, I carry out transactions on homme/cesium-terrain-builder docker image

Hi @safa833, which branch are you using? the quantized-mesh support is not merged in the master branch yet. See this pull request, it is based on this fork

Hi @ahuarte47, Yes, I'm in geodata branch, I was able to acquire successful result on your branch.
Thank you for your helping.

Is it possible to merge 2 tile sets that were already builded?
