I have a similar problem to this one: Mapbox Vector Tiles from Geoserver 2.11 in Mapbox GL JS

I'm trying to do the same (just with maplibre-gl-js, a fork of MapBox GL js v1) and GeoServer (2.20.1) with vector tile plugin. I got it working with openlayers, but not in maplibre-gl-js...

When I request the server like:


I get the actual tiles correctly but all data is converted (by GeoServer or GeoWebCache) to EPSG:900913 although the geometries in the database are all in EPSG:4326, which is a problem since maplibre-gl-js wants EPSG:4326 https://maplibre.org/maplibre-gl-js-docs/api/geography/.

Requesting with tileGrid EPSG:4326 like so:


is also not working because the x and y values in the url (filled by maplibre-gl-js "magic") have to be different.

How can I force the GeoServer not to convert the returned geometries into a different SRID ?

the code / config:

    this.map = new Map({
      container: 'map',
      minZoom: 0,
      maxZoom: 13,
      pitchWithRotate: false, // 3D Ansicht
      touchPitch: false,
      dragRotate: false, // rotation
      style: {
        version: 8,
        sources: {
          'plz-ort-source': {
            type: 'vector',
            scheme: 'tms',
            tiles: ['
            minzoom: 0,
            maxzoom: 14
        layers: [
            id: 'plz-ort',
            type: 'fill',
            source: 'plz-ort-source',
            'source-layer': 'plz-ort',
            layout: {},
            paint: {
              'fill-color': 'rgba(0, 0, 255, 0.4)',
              'fill-outline-color': 'rgba(0, 0, 255, 1)'
            id: 'foreground',
            type: 'raster',
            source: 'foreground-tiles',
            minzoom: 0,
            maxzoom: 14
      center: [10, 51], // starting position [lng, lat]
      zoom: 5 // starting zoom

And the GeoServer layer configuration: Bounds Cache Configuration

  • In short: It's like maplibre-gl-js is using EPSG:4326 to draw vector data on a EPSG:3857 grid (which is the same like 900913) to get the right tile index in the request-url. Sadly reprojection (or using a different srid) in maplibre-gl-js is not supported.

Just found the Problem, its not the projection or Geoserver. The Problem is the 'source-layer' name in the style -> layers Object must be the same as the requested layer name. So instead of

'source-layer': 'plz-ort',

it should be:

'source-layer': 'plz_ort_shape_1000',

like in the request url...
