Map Use & Analysis


Book Description

This book is designed to serve as an introduction to the fascinating world of maps. It explains how to use maps to obtain information about a wide variety of topics. Throughout the book, maps are viewed in a broad framework. Thus, the discussion includes mental maps, aerial photographs, remotely sensed images, computer-assisted cartography, and geographical information systems, in addition to traditional printed maps. The writing style is neither formalistic nor casual, with an emphasis on clarity of explanation. The discussions assume that the reader has no specific prior knowledge of the topic, so that even novice map users can understand and use the information and techniques presented.




History of Cartography


Book Description

This volume comprises the proceedings of the 2010 International Symposium of the ICA Commission on the History of Cartography. The nineteen papers reflect the research interests of the Commission which span the period from the Enlightenment to the evolution of Geographical Information Science. Apart from studies on general cartography, the volume, which reflects some co-operation with the ICA Commission on Maps and Society and the United States Geological Survey (USGS), contains regional studies on cartographic endeavours in Northern America, Brazil, and Southern Africa. The ICA Commission on Maps and Society participated as its field of study often overlaps with that of the ICA Commission on the History of Cartography. The USGS which is the official USA mapping organisation, was invited to emphasise that the ICA Commission on the History of Cartography is not only interested in historical maps, but also has as mandate the research and document the history of Geographical Information Science.

GIS Modules and Distributed Models of the Watershed


Book Description

Prepared by the Task Committee on GIS Modules and Distributed Models of the Watershed of ASCE. This report guides professionals in selecting the most advantageous applications of geographic information system (GIS) modules and distributed models for watershed runoff. Recent advances in technology offer hydrologic engineers, watershed managers, and data collection agencies unprecedented capabilities for storing and manipulating data. With the advent of Digital Elevation Models (DEM), Triangulated Irregular Networks (TIN), Digital Line Graphs (DLG), and GIS software, the use of watershed modeling among industry professionals has increased at an incredible rate. With this growth, it is increasingly difficult for practitioners to choose the most effective use of the technology. This report identifies state-of-the-art GIS hydrology analysis software and techniques, as well as GIS types and map projections. It covers data commonly required for hydrologic analysis, limitations of available data, and the integration of watershed hydrological analysis software and GIS techniques. The appendix highlights nine examples of watershed modeling systems, including the Watershed Modeling System (WMS), the Soil and Water Assessment Tool (SWAT), and the Hydrologic Model CASC2D.
