WebThe Normalized Difference Built-up Index (NDBI) uses the NIR and SWIR bands to emphasize man-made built-up areas. It is ratio based to mitigate the effects of terrain illumination differences as well as atmospheric effects. NDBI = (SWIR - NIR) / (SWIR + NIR) SWIR = pixel values from the short-wave infrared band WebWhat’s the difference between NIR (near-infrared) and CIR (color-infrared) imagery? NIR is the undetectable-by-the-human-eye fourth band directly collected from our sensors and delivered as an on-premises product. CIR is the derivative of that collection, colorized to make vegetation, water surfaces, and other impervious surfaces easier to see.
