What map projections are used in The National Map tiled base map services and dynamic overlay services?
The projection used for all tiled base map services in The National Map is the World Geodetic System 1984 (WGS 84) Web Mercator (Auxiliary Sphere) so that base map services can be used in combination with other common viewers.

What is the difference between tiled and dynamic services?
A tiled service contains cached tiles that render the map in small tile images. This allows the map to perform much faster when panning and zooming, compared to a dynamic service.

Tiled base maps are cached from global scale to a scale of 1:9...
