What is Geomaticts?

Geomaticts is an important knowledge in civil engineering. It help us on building things on the surface. As we know, Indonesia is located on uneven terrain. So, geomatics provide engineering a solution to know which place are the best place to construct a structure. In geomaticts, we develop a map which called topographic map. Topographic map contain elevation, contour line, and coordinate.

A contour line is a curve along which the function has a constant value. In other word, a contour line is a line which connect the same elevation above a given level, such as mean sea level. A contour map is a map illustrated with cotour lines. Topographic map is one of the example, it shows us valleys and hills, and the steepness of slopes.

In geomaticts, we will learn how to make a contour map. Engineer usually use theodolite as the instrument to measure the surface of land. We will earn vertical angel and horizontal angle (azimuth). The accuracy of theodolite to measure vertical angel is greater than a satellite. The earth weather changing every second, some time it makes the phenomena when the light are diffracted.  It is the reason why engineering still using this instrument.

What is CIvil Engineering?

Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings. Civil engineering is the oldest engineering discipline after military engineering, and it was defined to distinguish non-military engineering from military engineering. It is traditionally broken into several sub-disciplines including environmental engineering, geotechnical engineering, geophysics, geodesy, control engineering, structural engineering, biomechanics, nanotechnology, transportation engineering, earth science, atmospheric sciences, forensic engineering, municipal or urban engineering, water resources engineering, materials engineering, coastal engineering ,surveying, and construction engineering. Civil engineering takes place on all levels: in the public sector from municipal through to national governments, and in the private sector from individual homeowners through to international companies.

History

Civil engineering is the application of physical and scientific principles, and its history is intricately linked to advances in understanding of physics and mathematics throughout history. Because civil engineering is a wide ranging profession, including several separate specialized sub-disciplines, its history is linked to knowledge of structures, materials science, geography, geology, soils, hydrology, environment, mechanics and other fields.

Throughout ancient and medieval history most architectural design and construction was carried out by artisans, such asstonemasons and carpenters, rising to the role of master builder. Knowledge was retained in guilds and seldom supplanted by advances. Structures, roads and infrastructure that existed were repetitive, and increases in scale were incremental.

One of the earliest examples of a scientific approach to physical and mathematical problems applicable to civil engineering is the work of Archimedes in the 3rd century BC, including Archimedes Principle, which underpins our understanding of buoyancy, and practical solutions such asArchimedes' screw. Brahmagupta, an Indian mathematician, used arithmetic in the 7th century AD, based on Hindu-Arabic numerals, for excavation (volume) computations.
