API: Earth at Night

https://demo.ldproxy.net/earthatnight

Scope

The Earth at night, released by NASA. For more information, see NASA Earth Observatory "Night Lights". Raster tiles on zoom levels 0 to 6 were derived from a 54000x27000 pixel GeoTIFF image using rio-mbtiles.

Resource types: Map Tiles

Data source

License: Public Domain

To generate the MBTiles:

curl "https://eoimages.gsfc.nasa.gov/images/imagerecords/79000/79765/dnb_land_ocean_ice.2012.54000x27000_geo.tif" -o dnb_land_ocean_ice.2012.54000x27000_geo.tif
rio mbtiles dnb_land_ocean_ice.2012.54000x27000_geo.tif  -o dnb_land_ocean_ice.2012.54000x27000_geo.mbtiles --zoom-levels 0..6 --tile-size 512 --baselayer --title "Earth at Night" --description "GeoTIFF provided by NASA. Created using rio-mbtiles."
sqlite3 dnb_land_ocean_ice.2012.54000x27000_geo.mbtiles "insert into metadata (name,value) values ('minzoom',0);"
sqlite3 dnb_land_ocean_ice.2012.54000x27000_geo.mbtiles "insert into metadata (name,value) values ('maxzoom',6);"
sqlite3 dnb_land_ocean_ice.2012.54000x27000_geo.mbtiles "insert into metadata (name,value) values ('center','0,0,0');"

rio-mbtiles does not generate the minzoom, maxzoom and center entries in the metadata table, so these have to be set manually.
