Discrete Global Grids: A Web Book (2002) was edited by Michael F. Goodchild and A. Jon Kimerling and produced with the support of the National Center for Geographic Information and Analysis (NCGIA). This document reproduces the eight ‘chapters’ of the book, each of which deals with a specific aspect of discrete global grids as a method for specifying geographic location on the surface of the earth. The chapters are as follows:

Chapter 1: Developing an Equal Area Global Grid by Small Circle Subdivision, by Lian Song, A. Jon Kimerling and Kevin Sahr

Chapter Two: Interoperable Cooordinate Transformation and Identification of Coordinate Systems, by Daniel Specht

Chapter Three: Discovering, Modeling and Visualizing Global Grids over the Internet, by Yvan G. Leclerc, Martin Reddy, Lee Iverson and Michael Eriksen

Chapter Four: The Global Spatial Model, by Earl F. Burkholder

Chapter Five: EASE-Grid- A Versatile Set of Equal-Area Projections and Grids, by Mary J. Brodzik and Kenneth W. Knowles

Chapter Six: Ellipsoidal Area Computations of Large Terrestrial Objects, by Hrvoje Lukatela

Chapter Seven: A Seamless Global Terrain Model in the Hipparchus System, by Hrvoje Lukatela

Chapter Eight: Criteria and Measures for the Comparison of Global Geocoding Systems
