Enhanced Vegetation Index (EVI): A Modern Approach to Vegetation Health Monitoring
The Enhanced Vegetation Index (EVI) is an advanced remote sensing index designed to measure vegetation health and density. While similar to the well-known Normalized Difference Vegetation Index (NDVI), EVI improves […]
Vegetation Mapping: Revolutionizing Forest Monitoring with High-Resolution Satellite Imagery and LiDAR
Vegetation mapping is an essential tool for understanding and managing forests. It allows researchers and environmental agencies to monitor forest health, biodiversity, and environmental changes. Traditional forest monitoring methods rely […]
Urban Heat Island (UHI): Understanding and Technology for Measurement
Albedo is a measure of how much sunlight (solar radiation) a surface reflects. It is expressed as a percentage or a decimal between 0 and 1. A high albedo means a surface reflects most of the sunlight, while a low albedo means it absorbs more heat.
For example:
Snow and ice have a high albedo, reflecting most sunlight, which keeps them cooler.
Asphalt and concrete have low albedo, absorbing more heat and contributing to the Urban Heat Island effect.
