A system and method for combining image data are disclosed. Sensor data sets (210, 212) are received from sensors (112). An image metric (214) with slots (217) is generated by repeating the following for each sensor data set (210, 212) until a final slot (217) of the image metric (214) is reached: generating display data from a subset of a sensor data set (210) for a slot (217) of the image metric, and generating display data from a subset of a next sensor data set (212) for a next slot (217) of the image metric (214). An image generated from the image metric (214) is displayed.
