[gdal-dev] Better way to merge MBTiles ?

[Michael Otto]

Hello everyone,

I am in the process of merging several MBTiles files (same zoom level, 
same CRS) into one file.
(Unfortunately I am not allowed to use gdal_merge.py in my environment at 
the moment.)

Currently I am doing this via the detour "gdalbuildvrt".

Example commands:
'gdalbuildvrt complete.vrt Part1.mbtiles Part2.mbtiles ...'
'gdal_translate -of MBTILES -co TILE_FORMAT=WEBP complete.vrt 
complete.mbtiles'

I then create the pyramids using "gdaladdo". So far ok.

But the merging of the individual files takes a long time. Is there 
possibly a better and faster alternative?

Michael
