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.
