I have a number of mosaic datasets that I have created that I would like to upload to my ArcGIS online map. How would I go about doing this? I read somewhere to create a tile cache from the mosaic, then export it as a tile package, then use the "share package" tool to transfer it online. Will this work? I'm fairly new to GIS. (And if it makes a difference, these mosaics are all very large; around 300 MB a piece).
This doc section should help you, it outlines the steps necessary to get your mosaic data to ArcGIS Online
