Esri has published The GIS 20: Essential Skills, Third Edition, a book designed to prepare those who need to use a geographic information system (GIS).

According to Esri, the GIS 20 is aimed at readers who are new to or unfamiliar with GIS, such as professionals interested in using the technology on the job to conduct analysis and create maps, or a student majoring in a subject other than GIS who could benefit from geospatial knowledge.

Avoiding a focus on the inner workings of a GIS and sticking instead to teaching the tasks and functions most frequently and commonly used, this quick-start guide provides clear, step-by-step instructions on how to do common GIS tasks, says Esri. These include downloading shapefiles and using essential tools in the software, preparing data for a map, geocoding addresses, making thematic and other types of maps, mapping latitude and longitude points collected with a GPS, using aerial photography in maps, and publishing maps.

Author Gina Clemmer is president of New Urban Research, Inc., a social research and training company based in Portland, Oregon. She has spent her career teaching everyone from executives in New York City to residents of fishing villages in Alaska how to understand the core concepts and use the tools of GIS for decision-making.

“This book is an extension of my passion to help everyday people quickly learn the fundamentals of ArcGIS.”

The GIS 20: Essential Skills is available in print (ISBN: 9781589485129, 180 pages, US$49.99) and as an e-book (ISBN: 9781589485136, 180 pages, US$49.99). The print and e-book editions of the book can be obtained from online retailers or from Esri at esri.com/esripress.
