I am working on a solution to download map tiles based on given location:(latitude, longitude) and zoom level



Followed https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames



The key concept is to convert (latitude, longitude) to tile reference, eg. javascript code:



function long2tileX(lon,zoom) return (Math.floor((lon+180)/360*Math.pow(2,zoom)));



function lat2tileY(lat,zoom) return (Math.floor((1-Math.log(Math.tan(lat*Math.PI/180) + 1/Math.cos(lat*Math.PI/180))/Math.PI)/2 *Math.pow(2,zoom)));



For sample location (63.433772, 10.393456) and zoom level (17) this formulas return (69320, 35421) which is exactly what's needed to get the tile:



https://opencache.statkart.no/gatekeeper/gk/gk.open_gmaps?layers=topo4&zoom=17&x=69320&y=35421



Now I am struggling to achieve the same with ArcGIS maps.
The following CRS object is supplied:

https://services.geodataonline.no/arcgis/rest/services/Geocache_UTM33_WGS84/GeocacheBasis/MapServer/tile/17/47333/65439



What mathematical formula can I apply to follow the same scenario and get an accurate result?
