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.

Moving beyond the basics


So far, we've looked at some fairly basic applications of color in maps, coloring single features or adding a simple ramp to choropleth data. But sometimes we want to go beyond the basic and make a map that's slightly more sophisticated in the way color represents the data, sets a mood, or works with patterns.

Value-by-alpha

Value-by-alpha is a technique developed by cartographers Robert Roth, Andy Woodruff, and Zach Johnson, to enable the inclusion of a second variable relating to size. Traditionally, this has been done with cartograms. This technique involves distorting the size of an area, such as states or counties, to represent their share of some variable, such as population. The value-by-alpha technique is generally easier for map readers to interpret, as it preserves the expected size and shape of the area, and instead expands upon the darker equals more concept that map readers already interpret intuitively. Let's go back to that diverging scheme and make...
