I heard Google's Projection is Web Mercator.

Yahoo mentioned WGS84.

But I want to more detail information. (Detailed Projection : ex. Web Mercator)

I want to know YahooMaps's Projection. (If available)

Please.

Mapping Center Answer:

Sorry -- we don't know about Yahoo maps. 

In our online help, you can find out about the projections for Google Maps:

The ArcGIS Online tiling scheme uses 512 x 512 pixel tiles. When you choose this tiling scheme, the data frame of your source map document must use the WGS 1984 geographic coordinate system.

The Microsoft Virtual Earth/Google Maps tiling scheme uses 256 x 256 pixel tiles. When you choose this tiling scheme, the data frame of your source map document must use the WGS 1984 Web Mercator projected coordinate system.
