Overview of this book

ArcGIS is Esri's catalog of GIS applications with powerful tools for visualizing, maintaining, and analyzing data. ArcGIS makes use of the modern ribbon interface and 64-bit processing to increase the speed and efficiency of using GIS. It allows users to create amazing maps in both 2D and 3D quickly and easily. If you want to gain a thorough understanding of the various data formats that can be used in ArcGIS Pro and shared via ArcGIS Online, then this book is for you. Beginning with a refresher on ArcGIS Pro and how to work with projects, this book will quickly take you through recipes about using various data formats supported by the tool. You will learn the limits of each format, such as Shapefiles, Geodatabase, and CAD files, and learn how to link tables from outside sources to existing GIS data to expand the amount of data that can be used in ArcGIS. You'll learn methods for editing 2D and 3D data using ArcGIS Pro and how topology can be used to ensure data integrity. Lastly the book will show you how data and maps can be shared via ArcGIS Online and used with web and mobile applications.

Changing the coordinate system of a map


You now know how to determine the coordinate system for an existing map, and how to set one for a new map. But how do you change the coordinate system for a map or scene?

You might be wondering why you would want to change the coordinate system for a map. There are several reasons why you might want to change the coordinate system assigned to a map. As mentioned in the introduction, some coordinate systems are better suited for specific operations. If you need to measure areas or distances for analysis or editing, a projected coordinate system is best, especially for small areas such as a county, city, or district. If you are trying to show locations of features across large areas, such as a country or the world, then a geographic coordinate system is often best. If you are publishing as a web map then it might require the map be in the WGS 1984 Web Mercator (Auxiliary Sphere) coordinate system to conform with other datasets. So, if you need to do one...
