Hydrographic Surveys

Surveys whose principal purpose is the determination of data relating to bodies of water. A hydrographic survey may consist of the determination of one or several of the following classes of data: depth water; configuration and nature of the bottom; directions and force of currents; heights and times of tides and water stages; and location of fixed objects for survey and navigation purposes.

Physical Oceanographic Surveys

Studies or examination of the physical characteristics of ocean water such as salinity, temperature, density, etc., and dynamics such as tides, currents and waves.

Geodetic Surveys

Surveys being conducted primarily to establish, density and maintain the Philippine Geodetic Control (horizontal and vertical network).

Topographic/Photogrammetric Surveys

Determination of the horizontal and vertical positions of natural and man-made features of the earth's surface to be presented on a topographic map. Photogrammetric surveys include the use of aerial photographs.

Land Classification Surveys

These involve the classification of the country's unclassified public forests into alienable or disposable lands, as well as the evaluation of existing land classification projects and the verification of land classification status.
