Each pixel in those images contains measured values — stored as digital numbers (DNs) in raw data, or as surface reflectance in analysis-ready products — across different spectral bands: blue, green, red, near-infrared, and more. These bands tell us about vegetation health, water content, urban development, and land cover.</p> <p>This post introduces the core concepts of geospatial raster processing for Rust programmers who&rsquo;ve never worked with satellite imagery. We&rsquo;ll cover what the satellites measure, why their data looks the way it does, and what you can actually do with it.</p> <blockquote> <p><strong>Already know remote sensing?</strong> Jump ahead to <a href="/posts/002-end-to-end-workflow/">End-to-End Geospatial Processing with EORST</a> — a code-heavy walkthrough building a complete pipeline.</p> </blockquote>
