Switching Basemaps

[QingShi1]

Hi,

Anyone can help to explain what is 'the levels of detail' and " the levels of detail (LOD) are updated based on which basemap is selected"?

I will really appreciated!

From API reference com.esri.ags.layers.supportClasses.LOD

Levels of detail (LOD) for a TiledMapServiceLayer. Each LOD corresponds to a map at a given scale or resolution. Both resolution and scale are required fields. LOD's are automatically sorted based on scale, so setting level isn't necessary.
...

here is 20 levels.

Switching Basemaps (with updating LODs based on choosen base map)

Forum search is also helpful, set "LOD" as keyword and press "Search Now"
