Processing and Displaying Images in Earth Sciences
Computer graphics are stored and processed as either vector or raster data. Most of the data types that were encountered in the previous chapter were vector data, i.e., points, lines and polygons. Images are generally presented as raster data, i.e., as a 2D array of color intensities. Images are everywhere in geosciences. Field geologists use aerial photographs and satellite images to identify lithologic units, tectonic structures, landslides and other features within a study area. Geomorphologists use such images for the analysis of drainage networks, river catchments, and vegetation or soil types. The analysis of images from thin sections, the automated identification of objects, and the measurement of varve thicknesses all make use of a great variety of image processing methods.
