Keep the vector tiles updated

Once you have imported OpenMapTiles you can also keep it up to date by importing the latest OSM changes and regenerating the tables.

Import

You can either keep the database up to date based on the daily OSM change feed or import specific change files.

Keep Database Updated

You can use the new imposm3 feature to keep the database updated (thanks to the work by @stirringhalo). This will automatically download the OSM change feed and import it into the database. After each run you should also have a list of tiles that have updated.

docker-compose run update-osm

Import Change File

Given you have a file changes.osc.gz in your import folder. Once you ran the import command you should also have a list of tiles that have updated.

docker-compose run import-osm-diff

Generate Changed Tiles

After the import has finished imposm3 will store a list of tiles in text format in the diffdir. Copy the as tiles.txt to the import folder.

Now run the command to read the tilelist and write the vector tiles for it to a new MBTiles.

docker-compose run generate-changed-vectortiles
