Book Description
Considerations of scale underlie geographical study in all of its aspects. It is only slightly less in scope, in this respect, than the whole of the discipline. Reductionism in geography is necessary because of the great size of the earth, its numerous geographical elements, and the broad scope of geography. This scale of reality (1:1) must be reduced in order to study the areal variation of geography. Both perception and conceptualization have important scale implications. Geographers must frequently devise their own scales and must assure that they measure what they are said to measure. In geography, scale means measurement and, more specifically, the preciseness of measurement. Generalization and measurement must be differentiated in geography. Generalization belongs to hypothesis and theory; measurement belongs to empirical observation and the real world. Geographers have accepted scale as inherent to the profession but possibly have not regarded it commensurately with its true significance. Most geographic research is being conducted at small scales (63%) while only eight percent is at large scale. Thematic and special purpose mapping have deep scale considerations which are principally lodged in conceptualization, centered around the use of areal data as point data. The two principal scale applications, the reduction of area and the measurement of geographical associations and variations, require further specific and detailed study and research. (Author).

Book Description
As political, economic, and environmental issues increasingly spread across the globe, the science of geography is being rediscovered by scientists, policymakers, and educators alike. Geography has been made a core subject in U.S. schools, and scientists from a variety of disciplines are using analytical tools originally developed by geographers. Rediscovering Geography presents a broad overview of geography's renewed importance in a changing world. Through discussions and highlighted case studies, this book illustrates geography's impact on international trade, environmental change, population growth, information infrastructure, the condition of cities, the spread of AIDS, and much more. The committee examines some of the more significant tools for data collection, storage, analysis, and display, with examples of major contributions made by geographers. Rediscovering Geography provides a blueprint for the future of the discipline, recommending how to strengthen its intellectual and institutional foundation and meet the demand for geographic expertise among professionals and the public.

Book Description
Scale has long been a fundamental concept in geography. Its importance is emphasised in geographical information science (GIScience) where the computational domain necessitates the rigorous definition and handling of scale. Geographical information systems are now used in almost every walk of life, but scale is often handled poorly in such systems. Modelling Scale in Geographical Information Science is written by an international team of contributors drawn from both industry and academia, and considers models and methods of scaling spatial data in both human and physical systems. Divided into three sections to give a balanced coverage of the key problems, tools and models associated with scale: * Fractal Models * The Modifiable Areal Unit Problem * Changing the Scale of Measurement This book is an essential read for all GIScience researchers, advanced students and practitioners who want to delve more deeply into the scale issues of the spatial data and spatial models that form the basis of their analyses.

Book Description
This book is the first contemporary book to compare and integrate the various ways geographers think about and use scale across the spectrum of the discipline and includes state-of-the-art contributions by authoritative human geographers, physical geographers and GIS specialists. Provides a state of the art survey of how geographers think about scale. Brings together recent interest in scale in human and physical geography, as well as geographic information science Places competing concepts of scale side by side in order to compare them. The introduction and conclusion, by the editors, explores the common ground.

Book Description
This book explores different approaches to defining the concept of region depending on the specific question that needs to be answered. While the typical administrative spatial data division fits certain research questions well, in many cases, defining regions in a different way is fundamental in order to obtain significant empirical evidence. The book is divided into three parts: The first part is dedicated to a methodological discussion of the concept of region and the different potential approaches from different perspectives. The problem of having sufficient information to define different regional units is always present. This justifies the second part of the book, which focuses on the techniques of ecological inference applied to estimating disaggregated data from observable aggregates. Finally, the book closes by presenting several applications that are in line with the functional areas definition in regional analysis.

Book Description
This timely and fascinating book illustrates how applied geography can contribute in a multitude of ways to assist policy processes, evaluate public programs, enhance business decisions, and contribute to formulating solutions for community-level problems. The book showcases studies by applied geographers from across the globe collaborating with the public sector, businesses, NGOs and communities to demonstrate how geography Ð with its space and place perspective and its explicitly spatial methods and tools Ð has been employed to address significant real-world issues. The 20 case studies have been conducted at a variety of levels of scale and situational contexts, and employ a range of quantitative and qualitative approaches including spatial and statistical modelling, Geographic Information Systems (GIS), impact analysis and action research. This enlightening and informative book will prove an invaluable reference tool for academics, students and practitioners with a specific interest in applied geography and spatial analysis.

Book Description
Exploring Spatial Scale in Geography provides a conceptual and practical guide to issues of spatial scale in all areas of the physical and social sciences. Scale is at the heart of geography and other spatial sciences. Whether dealing with geomorphological processes, population movements or meteorology, a consideration of spatial scale is vital. Exploring Spatial Scale in Geography takes a practical approach with a core focus on real world problems and potential solutions. Links are made to appropriate software environments with an associated website providing access to guidance material which outlines how particular problems can be approached using popular GIS and spatial data analysis software. This book offers alternative definitions of spatial scale, presents approaches for exploring spatial scale and makes use of a wide variety of case studies in the physical and social sciences to demonstrate key concepts, making it a key resource for anyone who makes use of geographical information.
