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.

Reconciling 3D to 2D

The planet Earth may be round, but it is far from a perfect sphere. Because the Earth spins on an axis, centrifugal force actually bulges the center (equator) outwards. Gravity also plays a role as it is not constant across the entire Earth's surface, and many of the instruments that measure the Earth use gravity as a part of the measurement. These are some of the factors in geodesy. Geodesy is the science of accurately measuring and understanding Earth's geometric shape, orientation in space, and gravity field.

In the following two sections, you will get a brief overview of the pieces that make up your map projection. There is a lot of complicated math involved in these pieces, and to the regular GIS user there is little need to know the math; but if you find yourself doing more research work, it is highly recommended you research the math involved.

Geographic coordinate systems

To go from a 3D surface to a 2D plane, you first need to define the 3D surface. While there...
