In general, the purpose of Surveying and Mapping is applying how:
1. Determine the position any different form on the surface of the earth.
2. Determine the location of the height (elevation) everything is different above or below a field that is based on the average sea level – price / Mean Sea Level (MSL).
3. Determine the shape or surface relief of land and objects – objects that exist on the surface of the soil.
4. Determine the length, direction / angle, and the coordinates of a point (position) of another point on the surface of the earth, and calculate the area that has been restricted a certain area.
Scope of Survey and Mapping, among others:
a. National Land Agency (BPN), to determine the limits of government-owned land, owned by individuals and private property so it can be to make the ownership title (SHM), determine the amount of taxes to the government / Land and Building Tax (PBB).

e. Army Topographic Bureau, military field, in determining the situation Battlefield.
f. Maritime, tourism, transmigration and manufacturing projects – projects both small and large projects and maintenance.
g. Perancanaan City Planning etc.
h. Hold ground measurements for mapping the scales of certain of field-data of data transferred on the paper called MAP.
i. Photogrammetric measurement is one of the elements using aerial photographs.
j. Measurements hidografi that measurement to get the image the sea floor and others.
k. In addition to this, the land area is also required for the planning of the municipality, the expansion of an area, rsncana roads, irrigation plans and resettlement plans.
