Steven A. Roberts and Colin Robertson
Adopting a critical approach and highlighting many of the common research challenges of the field, this text helps students understand how GIS enables the digital representation of Earth's forms, patterns, and processes. Designed for users already familiar with GIS, this concise handbook invites
students to think broadly about the assumptions embedded in GIS practice today.
Note: each chapter contains equations and problems.
