Control Survey:
Made to establish the horizontal and vertical positions of arbitrary points.
Boundary Survey:
Made to determine the length and direction of land lines and to establish the position of these lines on the ground.
Topographic Survey:
Made to gather data to produce a topographic map showing the configuration of the terrain and the location of natural and man-made objects.
Hydrographic Survey:
The survey of bodies of water made for the purpose of navigation, water supply, or sub-aqueous construction.
Mining Survey:
Made to control, locate and map underground and surface works related to mining operations.
Construction Survey:
Made to lay out, locate and monitor public and private engineering works.
Route Survey:
Refers to those control, topographic, and construction surveys necessary for the location and construction of highways, railroads, canals, transmission lines, and pipelines.
