Abstract

Since the advent of satellite imagery, researchers have turned images into data and processed it. This program makes the first step easier in Stata, by turning a Windows 24-bit bitmap file into a Stata dataset with variables i and j (row and column of each pixel), r (red), g (green), and b (blue) on a scale of 0 to 255. Examples of uses for satellite images include projecting fishing productivity (Kemmerer et al. 1976), estimating economic growth (Henderson, Storeygard, and Weil 2012), and predicting poverty rates (Jean et al. 2016). Techniques for processing, filtering, or otherwise manipulating image data can also be used on any photograph.
