Mapping with ArcGIS Pro

By: Amy Rock, Ryan Malhoski

Overview of this book

ArcGIS Pro is a geographic information system for working with maps and geographic information. This book will help you create visually stunning maps that increase the legibility of the stories being mapped and introduce visual and design concepts into a traditionally scientific, data-driven process. The book begins by outlining the steps of gathering data from authoritative sources and lays out the workflow of creating a great map. Once the plan is in place you will learn how to organize the Contents Pane in ArcGIS Pro and identify the steps involved in streamlining the production process. Then you will learn Cartographic Design techniques using ArcGIS Pro's feature set to organize the page structure and create a custom set of color swatches. You will be then exposed to the techniques required to ensure your data is clear and legible no matter the size or scale of your map. The later chapters will help you understand the various projection systems, trade-offs between them, and the proper applications of them to make sure your maps are accurate and visually appealing. Finally, you will be introduced to the ArcGIS Online ecosystem and how ArcGIS Pro can utilize it within the application. You will learn Smart Mapping, a new feature of ArcGIS Online that will help you to make maps that are visually stunning and useful. By the end of this book, you will feel more confident in making appropriate cartographic decisions.

Chapter 6. All Maps Are Approximations of Reality

Maps can paint a pretty accurate view of our world or data, but there is a common reality of all maps: they are all incorrect. The world is in a constant state of change—rivers ebb and flow, things get built or destroyed, businesses open and close, people migrate, and the earth moves beneath our feet. This constant flux makes keeping track of everything time consuming and costly, but that is sometimes necessary. For most maps, using exact coordinates, displaying complex borders, and labeling every feature is not necessary. In this chapter, you will learn about the general types of maps, how to properly generalize data, and make your data stand out and easy to read.

In this chapter, we will cover the following topics:

  • The different styles of maps
  • Changing data to make more it more legible
  • Aggregating data
