I am having tiff images in NAD 1927 UTM coordinate System. I have created a source mosaic dataset with same coordinate system as the tiffs
I am planning to cache my map service. I am planning to create a derived mosaic dataset from source mosaic dataset and set the coordinate to WGS 1984 Web Mercator
My question is how and where is the transformation being applied. Is this happening on the fly ? For geographic transformation will it be using the fall back transformation ?
