Hello Jorge,<br>
<br>
If I've got it right the attached VRT should apply the nodata values
you require<br>
to katrina.tif, assuming you save it in the same directory.<br>
<br>
I didn't use gdal2tiles but instead used this VRT with the ctb-tile
utility<br>
(which makes heavy use of GDAL -<br>
<a class="moz-txt-link-freetext" href="https://github.com/homme/cesium-terrain-builder#ctb-tile">https://github.com/homme/cesium-terrain-builder#ctb-tile</a>) to
generate the JPEG<br>
tiles. Using the docker image you can call it as follows, assuming
katrina.tif<br>
and katrina.vrt are in the current working directory:<br>
<br>
mkdir katrina # for saving the tiles to<br>
docker run -v $(pwd):/data homme/cesium-terrain-builder ctb-tile
--output-dir /data/katrina --output-format JPEG --profile mercator
/data/katrina.vrt<br>
<br>
Best regards,<br>
<br>

Didn't work. Base tiles are generated, but overview tiles are not.
