Difference Vegetation Index (DVI)

The Difference Vegetation Index (DVI) is a simple vegetation index that quantifies vegetation presence and density by comparing near-infrared (NIR) and red band reflectance. It’s a straightforward way to assess vegetation presence and density, with higher DVI values indicating more vegetation. Formula:- DVI = NIR BAND – RED BAND It’s Works:- Calculating the Difference:- The DVI formula…

Atmospherically Resistant Vegetation Index (ARVI)

By Mohini Rajaram Sutar 1. What is ARVI? ARVI is a vegetation index developed by Kaufman and Tanré (1992). Designed to reduce atmospheric interference, especially from aerosols and scattering. Enhances accuracy in remote sensing of vegetation. 2. How it works: When an emergency occurs, the system sends an automatic alert to family members and the Arvi support team. The support team can…

Remote Sensing Concepts

Remote sensing (RS) is the science of acquiring information about the Earth’s surface without physical contact, using sensors mounted on satellites, drones, or aircraft. These sensors capture data across various spectral bands—such as visible light, infrared, and microwave—to analyze different features like vegetation, water bodies, and urban areas. The spatial resolution of an image determines…
