# How to combine multiple layers in one map

MapTiler Engine supports combining multiple layers into one map. This article contains basic information about the process. Please note that this option is only available in MapTiler Engine Pro.

With MapTiler Engine, you can combine multiple images together and create one big map overlay. Or you can combine images on different zoom levels, which are going to change as the end-user is zooming up and down through the final map, or [merge multiple MBTiles together](https://docs.maptiler.com/guides/map-tiling-hosting/data-processing/how-to-merge-tilesets-mbtiles).

## Combine multiple images together to create a mosaic

Creating a map mosaic is similar to [creating a map from an image](https://docs.maptiler.com/guides/map-tiling-hosting/data-processing/how-to-create-tiles-from-raster-data): you drag and drop your images, [georeference all of them](https://docs.maptiler.com/guides/map-tiling-hosting/data-processing/georeferencing) (either [visually](https://docs.maptiler.com/guides/map-tiling-hosting/data-processing/how-to-georeference-your-raster-data) or by other methods) and render the final map.

You can also make a color correction to give all images a unified seamless look.

## Combine images on different zoom levels

You can also combine images on different zoom levels, so the final product will be a map where different layers change as the end-user zooms in and out. The procedure is similar to the example above, but with multiple layers (which mostly consist of images taken by different devices at a different time) is even more important to make a color correction to give the map a unified seamless look.

## Merge multiple MBTiles

MapTiler can also [merge multiple MBTiles together](https://docs.maptiler.com/guides/map-tiling-hosting/data-processing/how-to-merge-tilesets-mbtiles). If you have an image you want to include in your map, process it first and render it into MBTiles format and then combine with the existing MBTiles file.
