A huge amount of tiles do not contain any data. In order to speed up the process of tile creation and to save lots of space we should skip all areas that do not contain any elevation data.

The current version of gdal2tiles allows

  • making tiles with No Data transparent (-a <NODATA>, --srcnodata=<NODATA>)
  • excluding transparent tiles from the tileset (-x, --exclude)

This will not speed up the process of creation but at least save space.
