Satellite 2021 distribution

The Satellite 2021 dataset is part of the MapTiler Satellite map. You can use it via API in MapTiler Cloud or download it for self-hosting as a MapTiler Data package. This article shows how to set up a sample layer from MapTiler Satellite 2021, downloadable from the MapTiler Data Satellite 2021 download page.

To optimize the size of this package, we prepared it in a WebP format with transparency. This format allows us to compress the size to hundreds of gigabytes (from the original terabytes of raw data).

The Satellite 2021 consists of two layers:

MapTiler Satellite Lowres

• around 80 MB
• overview of the world
• this dataset is part of the free MapTiler Server starter pack downloadable from MapTiler Data.

MapTiler Satellite Mediumres 2021

• around 500GB
• with detailed parts of the continental area.

To serve this data, we recommend using the MapTiler Server, which is available for free.

How to combine multiple layers using Virtual Tileset JSON

1. Download and unpack the MapTiler Server starter pack to your work directory from MapTiler Data.

2. Download the Satellite 2021 from MapTiler Data downloads section.

3. Move the downloaded file (maptiler-satellite-2021-XXXX.mbtiles) to your working directory.

4. Open the text file called “maptiler-satellite.json” and update the virtual source with the following lines:

"virtual_sources": [  
  {  
    "url": "maptiler-satellite-lowres",  
    "bounds": [  
      -20037508.342789, -20037508.342789244, 20037123.912877,  
      20037508.342789244  
    ],  
    "minzoom": 0,  
    "maxzoom": 6,  
    "_name": "satellite-lowres-2021"  
  },  
  {  
    "url": "maptiler-satellite-2021",  
    "bounds": [  
      -20037508.342789244, -13149614.7081853, 20037508.342789244,  
      17689362.572804667  
    ],  
    "minzoom": 3,  
    "maxzoom": 13,  
    "_name": "satellite-mediumres-2021"  
  }  
],

5. Launch MapTiler Server in this folder and open the administration.

6. Go to the Tiles section and rename the ID of Satellite Mediumres 2021 to maptiler-satellite-2021.

7. Now, you can see a seamless mosaic in Tiles as maptiler-satellite.json.
