Hyperspectral Satellites Explained: From Spectral Signatures to Decision Intelligence
Introduction: Earth Observation Is Entering a New Era For decades, the Earth observation industry has focused on three metrics: Higher resolution Faster revisit rates Wider coverage These advances have dramatically improved our ability to see the planet. Modern satellites can identify roads, buildings, vehicles, farmland, forests, and infrastructure with remarkable clarity. Yet a fundamental limitation…

What are the 5 types of satellite images?
What are the 5 types of satellite images? When working with satellite imagery, you can categorize them into various types based on the data they capture and the purpose they serve. Here are five common types of satellite images: 1. Visible Light Images: These images capture the visible portion of the electromagnetic spectrum, including colours…

What’s the difference between multispectral, hyperspectral, and SAR?
Multispectral and hyperspectral satellites A sensor’s spatial resolution, or how fine the pixels on the ground will be, is inversely related to its spectral resolution or how well it can discriminate between spectral bands. Because of this, satellites that record data along multiple spectral bands (hyperspectral) do not have the same spatial resolution as satellites…
