A total station is an integrated system which includes a microprocessor, electronic data collector, and storage system and is a combination of electronic theodolite and an electronic distance meter. This electronic instrument is used for the purpose of land surveying.The main functions of a total station includeangle measurement, distance measurement, coordinate measurement, and data processing. Total stations are used by civil engineers for topographical surveying. The application of a total station is seenin the areas of mining, mechanical and electrical construction, and meteorology. Highway and roadway management, transportation planning, and precision farming are also some of the key application areas of a total station. Compared to a conventional surveying instrument, the total station offers advantages of high accuracy of measurement, speeds up field work, eliminates manual errors of reading and recording, and provides accurate calculation of coordinates.Modernization of tool...
