Adding zoom levels past level 20

If I use the default map, the furthest you can zoom in is level 20 and the scale shows 20m/50ft. How can I zoom further than this? A concrete example of using custom zoom levels would be great. I basically want to get down to 1m.

Do custom zoom levels have to be set for each layer? overlay? or just the map itself?

Hi Dan,

Set map.ZoomLevelSet.CustomZoomLevels can make it zoom to further, and you should want set this value also: map.MinimumScale

And you don’t need set custom zoomlevelset for each overlay, but some backmap should cannot works well if you zoom into further level, because these levels don’t have target tile images.
