Only available for FORMAT=DIRECTORY. The standard WebMercator tiling scheme would be defined by “EPSG:3857,-20037508.343,20037508.343,40075016.686”. A tiling scheme for WGS84 geodetic could be “EPSG:4326,-180,180,360”. The tiling scheme for Finnish ETRS-TM35FIN (EPSG:3067) is “EPSG:3067,-548576,8388608,2097152”. When using such as custom tiling scheme, the ‘crs’, ‘tile_origin_upper_left_x’, ‘tile_origin_upper_left_y’ and ‘tile_dimension_zoom_0’ entries are added to the metadata.json, and are honoured by the OGR MVT reader.</span></span></div></blockquote><div dir="ltr" data-setdir="false"> </div><div dir="ltr" data-setdir="false">How can I get these metadata values for my CRS?
