So if I start a new map, and load in a basemap (Bing Hybrid) does this basemap set the default coordinate system for the map ?
Are any subsequent layers automatically transformed to match this ?
Is this true if they are WMS layers ?
Is this true if they are imported shapefiles ?
Does this apply if they are different geographic coordinate systems ?
To the best of my knowledge, there will be no datum transformation used, the data just will be reprojected - I'll try and confirm that for use with colleagues though.
