Annotations to Tile scheme in British National Grid
I am trying to export annotations as a tile in ArcGIS Pro, to be used in conjunction with an OS base map in ArcGIS Online. I need the tile to be exported in British National Grid. Below is the auto suggested scheme but this only goes to a maximum of level 18, when I need it to go to Level 22.
I have tried using the ArcGIS online/ Bing Maps/ Google maps option, however the tile created using this option is not in British National Grid and I am unable to change it as there is no option to do so. The resulting tile can not be used with the OS basemap.
Is there a way of changing the co-ordinate system when using this option? Is there another method that can be used to export the annotations into a tile in British national grid up to level 22?
Alternatively, is there another way to use annotations in ArcGIS online?
