Abstracting Geographic Information in a Data Rich World
Methodologies and Applications of Map Generalisation Series: Publications of the International Cartographic Association (ICA) Editors: Burghardt, Dirk, Duchene, Cécile, Mackaness, William (Eds.) Published 2014, 407 p.
Abstract
Research in the field of automated generalisation has faced new challenges in recent years as a result of technological developments in web-based processing, new visualisation paradigms and access to very large volumes of multi-source data generated by sensors and humans. In these contexts, map generalisation needs to underpin ‘on-demand mapping’, a form of mapping that responds to individual user requirements in the thematic selection and visualisation of geographic information. It is this new impetus that drives the research of the ICA Commission on Generalisation and Multiple Representation (for example through its annual workshops, biannual tutorials and publications in international journals). This book has a coherent structure, each chapter focusing on core concepts and tasks in the map generalisation towards on-demand mapping. Each chapter presents a state-of-the-art review, together with case studies that illustrate the application of pertinent generalisation methodologies. The book addresses issues from data gathering to multi scaled outputs. Thus there are chapters devoted to defining user requirements in handling specifications, and in the application and evaluation of map generalisation algorithms. It explores the application of generalisation methodologies in the context of growing volumes of data and the increasing popularity of user generated content.

Generalisation of geographic information: Cartographic modelling and applications
A Volume in the international cartographic association series. Published in april 2007, 282p. Editors: MACKANESS William, RUAS Anne, SARJAKOSKI L. Tiina.
Abstract
The International Cartographic Association Series reflects the state of professional cartography from an international perspective, and provides information on the application of new and developing technologies. Definitive volumes relate to different types of published mapping at a variety of scales and intended for diverse uses. Relevant applications of remotely sensed imagery and information technology during map generation are discussed, as are the international needs for the implementation of spatial database transfer standards, together with clearly set-out and potentially applicable policies for the future. Generalisation of Geographic Information presents the theoretical advancments in the field, to show how developments have advanced solutions to the point that they are being incorporated into existing commercal solutions. It also provides an over view of future research challenges. The reader will gain a clear picture of the breadth of cognate disciplines contributing to this field, as well as a thorough understanding of how these various methodologies are being applied to the real world.
