Spatial Autocorrelation and Spatial Filtering: Gaining Understanding Through Theory and Scientific Visualization de Daniel A. Griffith

Spatial Autocorrelation and Spatial Filtering: Gaining Understanding Through Theory and Scientific Visualization: Advances in Spatial Science

Autor Daniel A. Griffith
en Limba Engleză Hardback – 10 iul 2003
Exploiting the old maxim that "a picture is worth a thousand words," scientific visualization may be defined as the transformation of numerical scientific data into informative graphical displays. It introduces a nonverbal model into subdisciplines that hitherto employed mostly or only mathematical or verbal-conceptual models. The focus of this monograph is on how scientific visualization can help revolutionize the manner in which the tendencies for (dis)similar numerical values to cluster together in location on a map are explored and analyzed, affording spatial data analyses that are better understood, presented, and used. In doing so, the concept known as spatial autocorrelation - which characterizes these tendencies and is one of the key features of georeferenced data, or data tagged to the earth's surface - is further de-mystified. This self-correlation arises from relative locations in geographic space.

Recenzii

From the reviews:
"Daniel Griffith here makes an effort to expand the methodological toolbox of spatial analysis by presenting, analyzing, and meticulously demonstrating with numerous examples, the applications of spatial filtering … . In sum, many readers will find the book an appealing source of geographic and statistical material, richly supplemented by the use of scientific visualization … . Conceivably, spatial researchers will appreciate its invigorating introduction to mathematical-geographical properties of spatial datasets, and the statisticians will enjoy its many witty and challenging examples." (Oleg Smirnov, Journal of Regional Science, Vol. 44 (3), 2004)

Advances in Spatial Science
This series of books is dedicated to reporting on recent advances in spatial science. It contains scientific studies focusing on spatial phenomena, utilising theoretical frameworks, analytical methods, and empirical procedures specifically designed for spatial analysis. The series brings together innovative spatial research utilising concepts, perspectives, and methods with a relevance to both basic science and policy making. The aim is to present advances in spatial science to an informed readership in universities, research organisations, and policy-making institutions throughout the world.
 
The type of material considered for publication in the series includes:
 
- Monographs of theoretical and applied research in spatial science;
- State-of-the-art volumes in areas of basic research;
- Reports of innovative theories and methods in spatial science;
- Tightly edited reports form specially organised research seminars.
 
Manuscripts must be prepared in accordance with the guidelines for authors and editors that may be obtained from Springer-Verlag. Manuscripts considered for the series will be reviewed by independent experts to ensure their originality, scientific level, and international policy relevance.

Caracteristici

This book is about spatial statistics and spatial analysis.- The large number of georeferenced data analysis from various parts of the world is of particular interest to the reader. These datasets contain interval/ratio, binary, percentage and counts variables.- Enables the reader to effectively visualize and analyze spatial autocorrelation latent n georeferenced data.
