Hi there, Using the Vector Tiles plugin, we can request a GeoJSON vector tile in WGS-84 using WMS, because the bbox is in lon/lat and the srs is specified as epsg326. When we use the gmaps endpoint of GeoWebCache, we request a GeoJSON vector tile according to the Google Maps gridset, however, the feature coordinates in the GeoJSON vector tile are also expressed in EPSG:900913 / EPSG:3857.
Is there another GeoWebCache endpoint we should be using to request a vector tile using the Google Maps gridset, but receive the feature coordinates in the GeoJSON vector tile expressed in EPSG:4326? Many thanks in advance.
