The subject matter is canvassed along with theory, variety of examples, various types of survey techniques; survey instruments used in the field; measurement of distances, both vertical and horizontal; the direction of lines or angles between the lines, where as various levelling instruments, principles, techniques, methods applied in levelling are given in this text book. The subject matter is expressed in a simple language and practical manner. The treatment is clear, methodical as well as interesting and easy to follow. From the earlier seventh edition, the single volume is now split into two separate independent books: Book I ?:?Basic Surveying and Levelling Book II?:?Advance Surveying and Levelling. This division has been made to better cater to the diverse needs of students, professionals, and educators in the field of civil engineering, land surveying, and related disciplines. This Basic Surveying and levelling is arranged in the chapters like: Introduction, Scales, Linear measurements of distances, Chain Surveying and Ranging, Cross staff chain Surveying and Instruments, Compass Survey, Levelling, Permanent adjustments of Levels, Contouring, Plane Table Survey, Computation of Areas, Computation of Volumes, Minor Instruments, Global positioning system (G.P.S.) and Geographic information system (G.I.S.), Appendix I contains 170 Multiple Choice Questions and Appendix II showing Abbreviated Terms used in this book are given at the end of the book.
