How to implement schemes like shortbread

[mapzcom]

Question from a newcomer to vector tiles: How do you use schemes like OpenMapTiles vector tile schema or the Shortbread schema with Martin when generating vector tiles on the fly from a PostgreSQL database?

Maybe #343 is related, but it is still unclear to me. Thanks in advance!

The projection format WGS-84 - Spatial Reference ID SRID 4326 issues referenced in #343 is about how the data is served to a consuming service like a website mapper (Mapbox or Maplibre JavaScript component). The issue with projection is how the tiles "cut" up the underlying projection needs to match how the mapper/consumer wants to view the tiles so that the content will align.

To answer if you want to use the OMT or Shortbread, import it into QGIS and drag/drop into PostGIS extended PostgreSQL, once it is in the database Martin can then serve up the vectortiles. Other options are to make tiles and make them available to Martin through the config: https://maplibre.org/martin/config-file.html
