Question

When satellite images are analyzed a unit called the pixel is key to calculating what?

Answer 1

Land area

Step-by-step explanation:

This can be determined by clicking the raster output and then clicks then properties and the symbology tab while noting the pixels count displayed on the counting screen as you move.

Also, click the source tab while indicating the size of the cell and the linear units. Then multiply the cell size by the count to calculate in square units of the linear square being calculated. However, this only works when one can isolate the cells in the selected area only.

Answer 2

The answer is Land Area. If you know the distance and scale at which the image was captured, than one pixel of the image is equal to an X amount of area. The land area is represented as one pixel in an image called Resolution.
