It generally extends over large areas. The plane surveying is that type of surveying which does not take into account the curvature of the earth , and the surface of the earth is treated as a plane surface.
A geodetic survey determines the precise position of permanent points on the earth's surface, taking into account the shape, size and curvature of the earth. Geodetic surveying techniques are applied when areas or distances involved are so great that desired accuracy and precision results cannot be obtained by ordinary or plane surveying. Geodetic measurements are now being done with the use of orbiting satellites that are positioned 12, miles above the surface of the earth. The Field Surveys Section defines and manages a consistent coordinate system based on latitude, longitude and heights throughout Missouri.

Plane and Geodetic Surveying Plane and Geodetic Surveying blends theory and practice, conventional techniques and GPS, to provide the ideal book for students of surveying. Detailed guidance is given on how and when the principal surveying instruments theodolites, total stations, levels and GPS should be used. Concepts and formulae needed to convert instrument readings into useful results are fully and clearly explained. Rigorous explanations of the theoretical aspects of surveying are given, while at the same time a wealth of useful advice about conducting a survey in practice is provided. An accompanying least-squares adjustment program is available to download from www. His main research interests are in the area of computer-aided embodiment design, but he has also taught surveying for 25 years and now leads the Surveying Group at Cambridge University.

Plane and Geodetic Surveying the Management of Control Networks By Aylmer Johnson
Plane surveying is a branch of surveying in which the surface of the earth is considered as plane surface. Earth curvature is not counted for in distances. When survey extends over a large areas more than sq. Geodetic survey is used to provide control points to which small surveys can be connected.

Civil Lead. As we know that actual shape of the earth is an oblate spheroid. The length of the polar axis is shorter than the equatorial axis, but this difference is very small. So that earth is assumed as a sphere for students understanding. Surveying thus primarily divided into two parts.
Plane and Geodetic Surveying written by Aylmer Johnson is very useful for Civil Engineering Civil students and also who are all having an interest to develop their knowledge in the field of Building construction, Design, Materials Used and so on. This Book provides an clear examples on each and every topics covered in the contents of the book to provide an every user those who are read to develop their knowledge. The text presents the topic in a clear, simple, practical, logical and cogent fashion that provides the students with insights into theory as well as applications to practical problems. Plane and Geodetic Surveying written to meet exhaustively the requirements of various syllabus in the subject of the courses in B. Sc Engineering of various Indian Universities.
