One of the most notable early feats of surveyors was the measurement in the 1790s of the meridian from Barcelona, Spain, to Dunkirk, France , by two French engineers, Jean Delambre and Pierre Méchain , to establish the basic unit for the metric system of measurement. There are various types of levels such as dumpy level, Y level, cushing's level, tilting level, cooke's reversible level and automatic level instruments for leveling in surveying. Surveying relies for its accuracy and efficiency on having the right instruments. Jig telescope has optical micrometers which can measure to the 1000 th of an inch. Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. Measurement generally starts from the benchmark with known height determined by a pervious survey, or an arbitrary point with an assumed height. In conventional surveying, chain and tape are used for making linear measurements while compass and ordinary theodolites are used for making angular measurements. (1908.
