About Product
This book is an attempt to bring the different fields of Geoinformatics under one fold to help the novices in getting the subject matter at one place. The book includes Plane Surveying, Photogrammetry, Remote Sensing, Geographic Information System (GIS), and Global Positioning System (GPS). The subject matter emphasizes on the basic concepts and practices in use. The book has six sections as below:Section I introduces the Geoinformatics as a whole in the perspective of surveying as it has unlimited fields of applications. Section II provides basic concepts of errors in Plane Surveying, techniques of making linear and angular measurements for producing topographic maps of areas of moderate extents. Section III deals with Photogrammetry and technique of measurements on aerial photographs to produce topographic maps. Section IV is devoted to Remote Sensing, principle of this technique, and its application. It also presents various remote sensing missions launched, and the technique of image interpretation and digital image processing. Section V discusses the Geographic Information System(GIS) and its application, data models used in GIS, and how various spatial entities are related to each other in GIS environment through topology. Section VI is on Global Positioning System (GPS) which now finds its use in our day-today life. It is a technology for gathering (x, y, z) coordinates of points anywhere on the globe at any time making use of artificial satellites devoted for GPS. This section explains principle of working of GPS and its use in surveying.
