Raster data concepts

Most of the GIS concepts described also apply to raster data. However, raster data has some unique properties as well. Earlier in this chapter in the history of remote sensing, the focus was on earth imaging from aerial platforms. It is important to note that raster data can come in many forms including ground-based radar, laser range finders, and other specialized devices for detecting gases, radiation, and other forms of energy within a geographic context. For the purpose of this book, we will focus on remote sensing platforms that capture large amounts of earth data. These sources included earth imaging systems but also certain types of elevation data, and some weather systems where applicable.
