based on available class time and software requirements. ArcGIS Online and a web browser are sufficient to complete most of the tutorials and sections, except for the following chapters:

       Chapter 5 requires ArcGIS Pro (2.0+) to publish tile layers, and optionally requires ArcGIS Enterprise (10.5+) to publish map image layers.

       Chapter 8 has optional sections that require ArcGIS Pro (2.1+) and ArcGIS Enterprise (10.6+) with ArcGIS GeoAnalytics Server to publish geoprocessing services and perform big data analysis.

       Chapter 9 has optional sections that require ArcGIS Pro (2.0+) and ArcGIS Enterprise (10.5+) to publish image layers.

      Readers who don’t have ArcGIS Online subscriptions can create an ArcGIS Online trial account, which also comes with authorization to use ArcGIS Pro. The sample data and teaching PPT slides for this book are available on the Esri Press book resource page at esri.com/gtkwebgis3.

      I welcome your feedback at [email protected] and hope this book sparks your imagination and encourages creative uses of Web GIS.

      Acknowledgments

      I would like to thank everyone at Esri Press who supported this book project. Special thanks go to Catherine Ortiz for inviting me to write this book, Stacy Krieg for managing the project, Mark Henry for his excellent editing that greatly improved the quality of the book, and the designer and other colleagues for their valuable contributions.

      I would like to express my special appreciation to my Esri colleague Dr. Jie Chang, author of chapter 9. With his expertise on remote sensing, Dr. Chang’s contribution—imagery services and raster analysis—adds an important component of Web GIS that the previous editions of this book did not have.

      I am also grateful for the support of many other Esri colleagues and other contributors. This book would not be possible without the inspiration and support of Esri President Jack Dangermond. I sincerely thank Mourad Larif and Brian Cross for giving me the flexibility to work on the book; Clint Brown for providing guidance on the book contents; Derek Law and Geri Miller for reviewing the first edition; Professor Marci Meixler at Rutgers University for reviewing the second edition; and Jennifer Laws of Esri, Professor Jennifer Swift at the University of Southern California, Professor Bo Xu at California State University, and Danny Downing at the University of Florida for reviewing the third edition.

      Thanks to Julia Guard for her assistance in designing the slides, Bethany Scott and Sarah Ambrose for providing figures on big data analysis, Al Pascual and Eric Wittner for providing materials on virtual reality and augmented reality, Morakot Pilouk for providing materials on real-time GIS and hosting the sample stream service for the real-time GIS chapter, and Javier Gutierrez and Matthew Miller for reviewing the 3D web scene chapter. Thanks to Nathan Shephard, Jeremy Bartley, Jeff Shaner, Weston Murch, Meg Hartel, Laurence Clinton, Jinnan Zhang, Zikang Zhou, Dawn Wright, David DiBiase, Jianxia Song, Ismael Chivite, Tif Pun, Derek Law, Wei-Ming Lin, Jinwu Ma, Rupert Essinger, RJ Sunderman, Maosour Raad, and Brenda Watson for sharing enlightened discussions on Web GIS and for their support.

      This book was developed based on my work experience at Esri and my lecturing experience at Harvard University Extension, Henan University, the University of Redlands, the University of Texas at Dallas, the University of California, California State University, and many other universities. I want to thank my colleagues and students at these universities for providing feedback that has improved the content and structure of this book.

      Finally, and most importantly, I would like to thank my family for their love and support.

      Foreword

      By Clint Brown, Esri

      Much can be said about trends in information technology (IT). Perhaps first and foremost is the growing recognition and acceptance that GIS has evolved into an essential IT. GIS will be at the center of major advances in computing and IT. And many people are coming to the realization that geospatial expertise and systems will be essential for our planet’s future.

      Cloud computing—combined with IoT, smartphones, machine learning, and apps—enables an instrumented world where computing can be harnessed to analyze and respond to virtually any issue. GIS is already playing a critical role in these initiatives.

      Web GIS provides a comprehensive approach for working with virtually all information sources. Further, the data in each individual organizational GIS is being brought together virtually to create a comprehensive GIS of the world in the cloud. Each of us is creating and maintaining our own layers; because all GIS layers register onto the earth, we are also contributing to and assembling a larger societal GIS for our planet—our individual GIS systems of record are being integrated, extended, and deployed as systems for insight as well as communal systems for engagement.

      Virtually everyone is gaining access to this comprehensive, virtual GIS via web connections. GIS maps and apps are enabling all kinds of opportunities and engagements that extend far beyond our original system visions and goals.

      In the past decade, GIS has expanded far beyond the professional GIS community. Some interesting developments helped to drive this expansion. As apps became popular, people everywhere began to use online maps—the foundation for shared GIS. Almost overnight, everyone began to recognize the power of GIS as an enabling information platform for improved understanding, decision-making, efficiency, and communication.

      GIS provides a geospatial framework to integrate and interpret results. Over the past few decades, the mass adoption of the internet has led to a glut of information that we have come to know as “big data.” GIS provides a geographic context to make sense of it all, while also providing the capability and context to analyze that data in real time.

      People everywhere now recognize that GIS has become an essential computing infrastructure for every organization. Consequently, we expect the reach and impact of GIS to continue to expand at an accelerating pace.

      Chapter 1

      Web GIS introduction

      This chapter introduces the concept of Web GIS with the ArcGIS Web GIS platform. The chapter begins with an overview of Web GIS and its advantages, introduces the ArcGIS Web GIS platform, lists the technical evolutions in Web GIS, explains the basic content types and user levels in ArcGIS Online and ArcGIS Enterprise, and demonstrates the workflow to build Web GIS apps using the Esri® Story Map Tour SM template. This chapter familiarizes you with ArcGIS Online and ArcGIS Enterprise basic operations and workflows, and introduces flexible ways to build Web GIS apps that you will explore in other chapters.
