Top up display
The TopUp check box on the Image Analysis window is used to rotate the display so the top of the display is always oriented in the look direction of the raster dataset. This works similarly to an in-car navigation system where the choices are often either north is at the top of the screen (therefore, not using a top up option) or the screen rotates so the travel direction is always displayed at the top.
This tool only works when there is known associated rational polynomial coefficient (RPC) metadata for the raster dataset.
