The first single-project GIS textbook on the market, Understanding GIS: An ArcGIS Pro Project Workbook, fourth edition is an excellent resource for students and educators seeking a guide for an advanced, single-project-based course that incorporates GIS across a wide range of disciplines. It allows readers to progress through nine lessons using ArcGIS Pro software from Esri to find the best location for a new park along the Los Angeles River in Southern California. Each exercise offers step-by-step instructions, graphics to confirm exercise results, and explanations of key concepts. The book includes access to ArcGIS Desktop software, which includes ArcGIS Pro. Project data (real data, all of it updated) is downloadable from the book's resource web page.
