Generate EPSG:4326 Vector Tiles

Question

My goal is to create EPSG:4326 vector tiles (using Plate Caree) that can be served in Leaflet. I currently have a .shp file, which I converted to a geojson file using ogr2ogr. The main obstacle to begin with his seems to be how to create vector tiles from a shape file (or geojson).

Tippecanoe only produces Web Mercator tiles and the .mbtiles spec says reads:

"Only the Spherical Mercator projection is supported for presentation (tile display)".

Therefore, I assume the preferred output is a MVT file.

The trouble is, I can't find any tool out there that can produce vector tiles in EPSG:4326. Does anybody know of a good way to produce a .mvt file (or a similar output format) in 4326 from a shape file?

Answer 1

You can use the GDAL MVT Driver to create a directory of 4326 vector tiles using the -dco TILING_SCHEME="EPSG:4326,-180,180,360" with the -dco FORMAT=DIRECTORY flags. https://gdal.org/drivers/vector/mvt.html#dataset-creation-options

Or spin up GeoServer with the vector-tiles plugin to enable geowebcache to cache layers in 4326 vector tiles, also in a directory cache structure. https://docs.geoserver.org/latest/en/user/extensions/vectortiles/index.html
