The document presents various examples of remote sensing image analysis techniques, including image differencing, Euclidean distance change detection, and post-classification comparisons. It illustrates the effects of urban development and deforestation through satellite imagery from Sentinel-2 and Landsat 8. Visual representations of these analyses are provided to highlight changes in land cover over specified time periods.

1. Figure 1. a) Example of image differencing near Speedway, IN. Upper left: Sentinel-2 image, Nov. 11,
2015 (RGB 432). Upper right: Sentinel-2 image, Nov. 29, 2017 (RGB 432). Lower left: difference image
(NIR 2017 – NIR 2015). Lower right: an area that experienced > 10% increase in NIR reflectance due to
the construction of a new wing of the Allison Transmission Corporate Offices (Google Maps screenshot
below).
