In the very first step of creating a color-toned mosaic, you have to download MapTiler Server, and the MapTiler Satellite dataset and either create your own dataset or choose one of our high-res aerial imagery.
With these data sources, you composite it using the composite.json file. The process is described in a stand-alone how-to. Now it`s time to create a seamless mosaic.
Seamless color-toned mosaic
To color-tone the aerial imagery layer to fit the satellite layer, you need to modify the previously created satellite.composite.json file.
{
"layers": [
{
"name": "mediumres",
"url": "#maptiler-satellite-2021"
},
{
"name": "aerial-france",
"url": "#maptiler-aerial-france",
"opacity": [[3, 1], [6, 0]]
"color": { 20
"contrast": [3, 0.8], // [contrast, bias]
"gamma": [1.3, 1.4, 1.5], // [R, G, B] factors
"saturation": 1.3
}
}
],
"center": [0, 0, 1]
}
This will change the color of aerial-France based on the given parameters.
