However, this reduces the amount of energy that can be detected as the area of the ground resolution cell within the IFOV becomes smaller.
This leads to reduced radiometric resolution - the ability to detect fine energy differences.
However, if only 4 bits were used, then only 24=16 values ranging from 0 to 15 would be available.
Since the range of values displayed in a digital image normally starts at zero (0), in order to have 64 values, the maximum value possible would be 63.While the arrangement of pixels describes the spatial structure of an image, the radiometric characteristics describe the actual information content in an image.Every time an image is acquired on film or by a sensor, its sensitivity to the magnitude of the electromagnetic energy determines the radiometric resolution. The illustration on the left shows the image presented in two bits, or 4 shades of grey.Zircon (Zr Si O4) is an interesting mineral for a number of reasons.For a start it is evenly distributed within the Earth's crust.
