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.

Introduction


This chapter focuses on recipes that will help you visually inspect and better comprehend your data. The recipes in this chapter include methods of summarizing, inspecting, filtering, and styling data, based on spatial and temporal attributes so that you can get a better feeling for your data before you perform analysis. The primary goal is to create some visuals or summaries of data that allow you, the human, to utilize your brain's ability to identify patterns of interest. The better you understand your data, the easier it is to pick appropriate analysis methods later.
