What is the value of DN?
DN Factor, also called DN Value, is a number that is used to determine the correct base oil viscosity for the lubrication of various types of bearings. It can also be used to determine if a bearing is the correct choice for use in a given application. It is a product of bearing diameter (D) and speed (N).
What is a DN range?
Each pixel also has a numerical value, called a digital number (DN), that records the intensity of electromagnetic energy measured for the ground resolution cell represented by that pixel. Digital numbers range from zero to some higher number on a gray scale.
What does DN mean in remote sensing?
Digital Number
Remote Sensing Fundamentals The sensor turns the energy into a voltage, which an analog to digital converter turns into a single integer value (called the Digital Number, or DN) for the energy. Alternatively a digital detector can store the DN directly.
What is the full form of DN?
Abbreviation : DN DN – Doctor of Naprapathic Medicine. DN – District Nurse. DN – Diameter of Nozzle. DN – Discrepancy Notice. DN – Debit Note.

How do you convert DN to surface reflectance?
It is possible to manually convert these DNs to ToA Reflectance using a two-step process. The first step is to convert the DNs to radiance values using the bias and gain values specific to the individual scene you are working with. The second step converts the radiance data to ToA reflectance.
How do you find the DN value in an envi?
Eric Ariel is right.. you can check the DN value of any band in any of the remote sensing software like ERDAS, ENVI, eCognition. you just need to roll the cursor on the pixel. it will show you the DN value..
How do I find my DN in ENVI?
There are several ways to view your data values: – From the Display menu ->Tools, bring up the Cursor Location/Value tool. This will show you the DN of the current display pixel. If you have a single band displayed, it shows the DN of that band. If you have an RGB displayed, it shows the DN of each band of the display.

What does dB mean?
decibel
decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.
