ARCMAP-IFOV

[ChuckTurlington]

Hello,

I am using ArcMap 10.2.1.

I am learning about how aerial imagery is photographed.  I understand there is a "cone" that captures the Instantaneous Field of View.  I have also read that the optics are rotating.  So I have to ask; does the satellite optics scan a triangular swath that rotates to create the cone of instantaneous view?

There are remote sensing tutorials on line that will answer these questions.

IFOV (Instantaneous Field of View)
A measure of the spatial resolution of a remote sensing imaging system. Defined as the angle subtended by a single detector element on the axis of the optical system. IFOV has the following attributes:

• Solid angle through which a detector is sensitive to radiation.
• The IFOV and the distance from the target determines the spatial resolution. A low altitude imaging instrument will have a higher spatial resolution than a higher altitude instrument with the same IFOV.
