Any technical book that reaches its third edition in 10 years is fulfilling a role for the scientific community over an extended period. Thus, the publication of the third edition of Collecting Spatial Data signifies that this monograph is continuing to provide an effective summary of the state of the art of the design of spatial networks.
Measuring of spatially varying quantities, such as geological strata or daily rainfall, is a critical problem both for research and for the operation of a modern society. To monitor the state of the environment, manage our use of the environment, and set future policies for the environment, we need to know the spatial and temporal distribution of a wide range of variables on land, in the ocean, and in the atmosphere. At the same time that communities are keen to gather information about the environment, they are also reluctant to spend a lot of money on such apparently mundane activities. Thus, efficiency is invariably a key factor in designing a spatial network for such monitoring.
