The Level is an indispensable instrument for surveyors, used to accurately measure a plane that is truly tangential to the surface of the Earth. It is an instrument consisting of a telescope fixed parallel to the level. The enormous development of railway construction in the first half of the nineteenth century led to the demand for levels that were quick and easy to use.
Topography studies instruments, surveying techniques, calculus and plans to represent graphically in scale a part of the Earth surface on a map, indicating its details like streets, rivers, buildings, cultivations… Topography is a very antique science. Egyptians measured lands along the Nile for tracing borders after periodic overflows of the river. Greeks and Romans used some topographical method very precise; some topographers teams (“gromatici”) following Roman legions traced borders and divided conquered lands in regular plots, then described and represented on copper plates. Arabs used topography to made maps and to measure agrarian surfaces and lands for cadastral use.
