Enhanced Line Rate imagery

A new term doing rounds of Remote Sensing circles is Enhanced Line Rate imagery. What actually is Enhanced Line Rate? Pushbroom sensors such as IKONOS acquire data using a line of sensors arranged perpendicular to the flight direction of the spacecraft. It is a large focal plane detector array, capable of generating thousands of line… Continue reading Enhanced Line Rate imagery
