I'm not familiar with mapbox-gl-leaflet plugin, but it seems it's not sufficient to display ArcGIS Esri vector layers. ArcGIS has it's own Esri Leaflet Vector Tile plugin (https://github.com/Esri/esri …

As you wrote in your comment, your image is in EPSG:4326 CRS, so it cannot show correctly in default Leaflet map that uses EPSG:3857 CRS. Since Leaflet (unlike OpenLayers) supports only one CRS per ma …

One possible solution is to create second map that's copy of the original one, but not displayed. This one can then be used to set zoom independent of the displayed map and retrieve features from ther …

Library proj4.js (http://proj4js.org/) is usually used for coordinated transformation in JS. To use it one needs CRS definition, which can be easily found on epsg.io site. SWEREF 99 TM coordinate syst …
