Richard Chorley & Peter Haggett 
Integrated Models in Geography (Routledge Revivals) [EPUB ebook] 

First published in 1967, this book explores the theme of geographical generalization, or model building. It is composed of five of the chapters from the original Models in Geography, published in 1967. The first chapter broadly outlines this theme and examines the nature and function of generalized statements, ranging from conceptual models to scale models, in a geographical context. The following chapters deal with mixed-system model building in geography, wherein data, techniques and concepts in both physical and human geography are integrated. The book contains chapters on organisms and ecosystems as geographical models as well as spatial patterns in human geography.

This text represents a robustly anti-idiographic statement of modern work in one of the major branches of geography.
