Urban Air Pollution Monitoring by Ground-Based Stations and Satellite Data
Multi-season characteristics from Lanzhou City, China
AvMikalai Filonchyk,Haowen Yan
Häftad, Engelska, 2019
1 750 kr
Skickas inom 5-8 vardagar
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.
Spatial Similarity Relations in Multi-scale Map Spaces

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.

Description Approaches and Automated Generalization Algorithms for Groups of Map Objects
AvHaowen Yan
Inbunden, Engelska, 2019
1 623 kr
Skickas inom 10-15 vardagar
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.
