    2. ENVS720 Spatial resolution Spatial resolution refers to the size of the smallest possible feature that can be detected. Spatial resolution of passive sensors depends primarily on their Instantaneous Field of View (IFOV). IFOV is the angular cone of visibility of the sensor (A) IFOV determines the area on the Earth's surface which is "seen" from a given altitude at one particular moment in time (B). The size of the area viewed is determined by multiplying the IFOV by the distance from the ground to the sensor (C). Area on the ground is called the resolution cell and determines a sensor's maximum spatial resolution.
