Update the existing tileset (merging tiles) in MapTiler Pro
It would be nice to have possibility to update existing tileset (MapTiler tiles generated before) with new input raster and merge automatically new tiles into old tile tree – for example when updating subset of existing areas - such as large aerial photo or large base map rendered previously.
It is now possible to merge existing MBTiles to produce a single MBTiles file with MapTiler Pro 0.6.4.
There is a graphical user interface for this feature (after you open an MBTiles file in MapTiler) and command line tool called “merge_mbtiles” available for all MapTiler Pro customers.
The tool can be used to create a seamless map from multiple MBTiles, or update existing large dataset by glueing a newly rendered overlay over the existing tileset (such as updating aerial photo of small region in existing map).

Merging multiple files together to produce a single output is a feature of MapTiler Pro.
Just drag&drop multiple files to the application, these can be even in different coordinate systems (such as different UTM zones) and the software produces a single seamless layer.
All of this can be automated on the command-line. From version 0.6 it is possible to specify the zoom levels for individual files also from the graphical user interface. See this video tutorial:

The update of already rendered large tilesets is on our TODO list.
