About the book
Joseph Kerski and Jill Clark co-authored the book The GIS Guide to Public Domain Data for Esri Press.
The book aims to help GIS users, instructors and others develop their skills in finding,using and applying spatial data to solve problems. It also highlights some of the issues GIS practitioners are likely to encounter working with spatial data, including format, pricing, copyright, cloud computing and more.
The book also provides context for the development of the numerous data portals we see today in terms of the organizations that collect and provide access to data, and the policies that govern data use. Each chapter in this book discusses the major issues associated with public domain spatial data by presenting both sides of the debate, helping you appreciate the complexity of these issues and their relevance in your everyday work with GIS. This information will help users in all areas of the GIS community become critical users of data – mindful of provenance, quality, and appropriate use.

Dear Joseph,
Received your new book yesterday and read the first chapter last night. I want to congratulate you on producing a truly wonderful book for the GIS community. I am very impressed with the writing, organization and the telling of the story. This book talks to me and has already answered many of my questions about information and spatial data.
Thank you very much for creating this remarkable book,
Martin

Dear Joseph,
I had the distinct pleasure of receiving a desk copy of this text book a few months back. It is certainly a must read for anyone looking to work with satellite or census data. At my stage of a GIS career I found the book very useful and educational. I would recommend the book for any GIS professional who has been in the game for a while but may not have considered data use issues explicitly. Also, any person looking to find some great open data sources should consider this guide as a definitive source!
Congratulations on this great book!
