Bash script & style to recreate the point map on openaddresses.io.
- script assumes blank ubuntu AMI & working aws-cli credentials for the data.openaddresses.io bucket
- resulting mbtiles file should be uploaded to mapbox.com
- .tm2 style can then be used in Mapbox Studio with source set appropriately
