Document Summary

A common problem encountered in boundary survey and other type of survey is to determine the perpendicular distance of a point from a line. Topographic (mapping): surveys are preliminary surveys used to locate the horizontal and vertical positions of (cid:374)atu(cid:396)al a(cid:374)d (cid:272)ultu(cid:396)al (cid:894)a(cid:396)tifi(cid:272)ial(cid:895) featu(cid:396)es i(cid:374) a defi(cid:374)ed a(cid:396)ea o(cid:374) the ea(cid:396)th"s su(cid:396)fa(cid:272)e. Mapping (drafting) is the process of creating hardcopy or softcopy topographic maps. Whats a topographic map ?a topographic map is a detailed and accurate graphic representation of cultural and natural features on the ground , as well as the configuration of the earths surface. -- >they not only show planimetric positions but also indicate relief by some methods, the map includes symbols that represent such features as streets buildings streams and woods. These symbols are constantly refined to better relate to the features they represent, improve the appearance or readability of the map or to reduce production cost.
