Causes And Consequences Of Map Generalization

by Elsa Joao

Overview

This text describes late-1990s understanding of map generalisation in the context of paper maps and GIS. Its particular value should be in helping to further automate and measure the process of map generalisation.; The research has concentrated on quantifying generalisation effects and on analysing how these effects of generalisation locked into the maps were measured. Elsa Joao's book covers the background to the problems of map generlasation; the methodology developed by the author to investigate the consequences of the map generalisation; a detailed description of results, and a conclusion that draws together consequences for the broader applications to GIS.

Editorial Reviews

Joao (geography and environment, London School of Economics) treats perhaps the greatest remaining research problem in Geographical Information Systems (GIS): map generalization, where maps for the same region diverge dependent on their scale. In this perhaps first text to focus on the precise quantification of this phenomenon, the author presents a new method of locking generalization into maps (derived from her doctoral thesis research). The measurement of displacement proves to be the key indicator of cartographic generalization. Includes sample monochrome copies of the Ordnance Project European study area maps, and raw data for each feature per scale. Annotation c. by Book News, Inc., Portland, Or.
