Geographic information systems (GIS)--a central repository of geographic data collected from various sources, including satellites and GPS--is emerging as one of the most intriguing and promising high-tech fields. This easy-to-understand resource provides technical and nontechnical professionals, regardless of their background, with an accessible and practical guide to important GIS know-how.
Applications of remote sensing and geographic information systems to resource management and environmental research.
This comprehensive textbook on Remote Sensing and Geographical Information System (GIS) presents the fundamentals of the emerging technology of remote sensing combined with GIS. It provides sufficient knowledge of these technologies applied in different fields avoiding voluminous details required at research level. The first part introduces the basics of remote sensing leading up to data analysis. An exhaustive discussion on various types of sensors and their uses has been included to make the readers understand clearly their utilities. The second part presents the highly technical field of Geographic Information System, a tool that now finds applications in almost all fields of engineering, science, geography, planning, and decision-making.

The recent emergence and widespread use of remote sensing and geographic information systems (GIS) has prompted new interest in scale as a key component of these and other geographic information technologies. With a balanced mixture of concepts, practical examples, techniques, and theory, Scale in Remote Sensing and GIS is a guide for students and users of remote sensing and GIS who must deal with the issues raised by multiple temporal and spatial scales. Sixteen pages of full-color photographs help demonstrate key points made in the text.
Sustainability has been increasingly embraced as an overarching policy goal, and communities have been called to be active participants on the path towards attaining a balance between fundamental human needs and ecological resilience. Community-based organizations (CBOs) can benefit from using GIS in building community assets and developing well-conceived sustainability initiatives, but GIS has not yet been widely used for those purposes in CBOs. This book illustrates how geographic information (such as maps) can be useful in community development drawing from service-learning GIS projects, and argue that economic theories of sustainability and spatial thinking can be of help in building sustainable community. It also discusses the application of vehicle routing problems for sustainable waste collection; spatio-temporal visualization and analysis techniques in GIS; GIS applications in modern crop protection; role of geographic information system for water quality evaluation; and the use of remote sensing and GIS for groundwater potential mapping in crystalline basement rocks.
As the use of geographical information systems develops apace, a significant strand of research activity is being directed to the fundamental nature of geographic information. This volume contains a collection of essays and discussions on this theme. What is geographic information? What fundamental principles are associated with it? How can
Most government agencies and private companies are investing significant resources in the production and use of geographical data. The capabilities of Geographical Information Systems (GIS) for data analysis are also improving, to the extent that the potential performance of GIS software and the data available for analysis outstrip the abilities of
Surveying and mapping has recently undergone a transition: from discipline-oriented technologies, such as geodesy, surveying, photogrammetry and cartography, to the methodology-oriented integrated discipline of geoinformatics based on GPS positioning, remote sensing, digital photography and GIS for data manipulation and data output. This book presents the required basic background for remote sensing, digital photogrammetry and GIS in the new geoinformatics concept in which the different methodologies must be combined. For remote sensing, the basic fundamentals are the properties of electromagnetic radiation and their interaction with matter. This radiation is received by sensors and platforms in analogue or digital form, and is subject to image processing. In photogrammetry, the stereo-concept is used for the location of information in 3D. With the advent of high-resolution satellite systems in stereo, the theory of analytical photogrammetry restituting 2-D image information into 3D is of increasing importance, merging the remote sensing approach with that of photogrammetry. The result of the restitution is a direct input into geographical information systems in vector or in raster form. The fundamentals of these are described in detail, with an emphasis on global, regional and local applications. For data integration, a short introduction into the GPS Satellite positioning system is added. This textbook will appeal to a wide range of readers, from advanced undergraduates to all professionals in the growing field of geoinformation.
