The third chapter represents the “Satellite remote sensing”. The fourth chapter analysed “Global Positioning System”, it include the GPS procedure, types and developments. The fifth chapter is “Introduction to Geographical Information System” and covered basics information about GIS. The sixth chapter included applications of remote sensing, geographical information system and Global positioning systems. This book is very useful to bachelor, post graduates’ degree of geography and research scholars can get the some ideas and knowledge about the Geospatial Technologies. This book is prepared with very basic and common information. Geographic knowledge of these technologies will provide students with the skills needed to meet the demands of their diverse careers in the global workplace.

Introduction to Geographic Information Technology is an up-to-date introduction that provides a balanced treatment of concepts and techniques required for GIS and Remote Sensing. The book focuses on foundation, integration and practical applications of GIS, Remote Sensing, GPS and other areas of Geographic Information Technology. It also considers how the technology. It also considers how the technology works. The book can be used to give the reader a quick tour through the world of Geographic Information Technology, to help the reader develop a thorough understanding of Geographic Information Technology or as a source of reference information. The authors are scientists, practitioners and teachers who understand student requirements in developing basic foundation required to build specific skills in Geographic Information Technology. The book presented with examples on the subject, makes the study of any branch of Geographic Information Technology from the broader context of geography in general to spatial information resource management in particular. It gives a wholesome coverage of GIS, Remote Sensing and GPS principles as well as data structures, spatial database modeling and their applications.

Geomatics is a neologism, the use of which is becoming increasingly widespread, even if it is not still universally accepted. It includes several disciplines and te- niques for the study of the Earth’s surface and its environments, and computer science plays a decisive role. A more meaningful and appropriate expression is G- spatial Information or GeoInformation. Geo-spatial Information embeds topography in its more modern forms (measurements with electronic instrumentation, sophisticated techniques of data analysis and network compensation, global satellite positioning techniques, laser scanning, etc.), analytical and digital photogrammetry, satellite and airborne remote sensing, numerical cartography, geographical information systems, decision support systems, WebGIS, etc. These specialized elds are intimately interrelated in terms of both the basic science and the results pursued: rigid separation does not allow us to discover several common aspects and the fundamental importance assumed in a search for solutions in the complex survey context. The objective pursued by Mario A. Gomarasca, one that is only apparently modest, is to publish an integrated text on the surveying theme, containing simple and comprehensible concepts relevant to experts in Geo-spatial Information and/or speci cally in one of the disciplines that compose it. At the same time, the book is rigorous and synthetic, describing with precision the main instruments and methods connected to the multiple techniques available today.

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.

New methods of acquiring spatial data and the advent of geographic information systems (GIS) for handling and manipulating data mean that we no longer must rely on paper maps from a single source, but can acquire, combine, and customize spatial data as needed. To ensure quality results, however, one must fully understand the diverse coordinate frameworks upon which the data are based. Datums and Map Projections provides clear, accessible explanations of the terminology, relationships, transformations, and computations involved in combining data from different sources. The first half of the book focuses on datums, exploring different coordinate systems and datums, including two- and three-dimensional representations of Earth coordinates and vertical datums. After an overview of the global positioning system (GPS), the author introduces the fundamentals of map projections and examines the different types. He then presents models and procedures for transforming directly between data sets. The final chapter presents case studies of projects that illustrate the types of problems often encountered in practice. Newcomers to the field will welcome this treatment that, instead of detailed mathematics, uses lucid explanations and numerous examples to unravel the complexities of the subject. For more experienced readers, the book is a valuable reference that answers specific questions and imparts a better understanding of transformation operations and principles. Features
