Abstract
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. Drainage networks, the outlines of geologic units, sampling locations and topographic contours are all examples of vector data. In Chapter 7, coastlines are stored in a vector format while bathymetric and topographic data are saved in a raster format. Vector and raster data are oft en combined in a single data set, for instance, to display the course of a river on a satellite image. Raster data are oft en converted to vector data by digitizing points, lines or polygons. Conversely, vector data are sometimes transformed to raster data.
