This book focuses on the generalization of map features, providing
descriptions and classifying groups of map objects into six
categories: point clusters, groups of contours, road networks,
river networks, continuous areal features and discrete areal
features. Discussing the methods and algorithms in map
generalization in equal measure, it also describes the approaches
for describing map features. The book is a valuable reference for
graduates and researchers who are interested in cartography and
geographic information science/systems, especially those in
automated map generalization and spatial databases construction.
This book examines air pollution of a big city using multi-year and
multi-season data from ground-based air monitoring stations and
satellite sounding data, which provides more clear and detailed
information on the main sources of air pollution, the long-term
trend of pollution, the influence of meteorological parameters on
pollution levels, and trajectories of polluted air masses. For
example, the book shows that particulate matter from local sources
is transported from deserts to create air quality challenges. It
also analyzes the effects of desert and semi-desert landscapes on
high concentrations of pollutants.
How does one determine how similar two maps are? This book aims at
the theory of spatial similarity relations and its application in
automated map generalization, including the definitions,
classification and features of spatial similarity relations.
Included also are calculation models of spatial similarity
relations between arbitrary individual objects and between
arbitrary object groups, and the application of the theory in the
automation of the algorithms and procedures in map generalization.

Surveying is a branch of Geomatics, focusing on measuring and
recording the positions and elevations of the points on the Earth
surface. It is an old discipline but it has absorbed fresh
nutrition from satellite-based surveying, remote sensing and
geographic information science in recent decades. Therefore, this
book consists of two parts: conventional surveying and modern
surveying. The former discusses the surveying principles and
methods using conventional surveying instruments; the latter
addresses the principles in geographic information systems, remote
sensing and global positioning systems.Audience - Postgraduate
