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.

Gdalbuildvrt could help you

@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

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