Raster analysis is a classic area in GIS analysis. This chapter shows you some of the most important and common tasks of raster analysis. Elevation data is commonly stored as raster layers, and in this format, it is particularly suitable to run a large variety of analysis. For this reason, terrain analysis has traditionally been one of the main areas of raster analysis, and we will show you some of the most common operations that are related to Digital Elevation Models (DEM), from simple analysis, such as slope calculation, to more complex ones, such as drainage network delineation or watershed extraction.

Overview of this book
QGIS is a user-friendly, cross-platform desktop geographic information system used to make maps and analyze spatial data. QGIS allows users to understand, question, interpret, and visualize spatial data in many ways that reveal relationships, patterns, and trends in the form of maps. This book is a collection of simple to advanced techniques that are needed in everyday geospatial work, and shows how to accomplish
them with QGIS. You will begin by understanding the different types of data management techniques, as well as how data exploration works. You will then learn how to perform classic vector and raster analysis with QGIS, apart from creating time-based visualizations. Finally, you will learn how to create interactive and visually appealing maps with custom cartography. By the end of this book, you will have all the necessary
knowledge to handle spatial data management, exploration, and visualization tasks in QGIS.
