TOPOGRAPHIC SURVEY

Topographic surveys are made to determine the configuration of the Earth's surface, defined by the elevation of points on a portion of land and the location of natural and man-made features on it. Topographic maps are presented as contour showing the elevation data and symbols representing structures and features on a plot.

LiDAR applications in power and energy in baseline mapping is ideal for exploration, resource management, terrain mapping, and feasibility studies. The LiDAR data may serve useful for multiple purposes from planning to operations, volume computations, site monitoring, and rehabilitation of power and energy in the Philippines. For forest areas or highly vegetated lands, such as those in the Philippines, the LiDAR equipment is recommended since it is capable of penetrating vegetation and makes it possible to acquire detailed ground or topographic points through an aerial survey. For monitoring site status and physical condition of facilities that may be difficult or unsafe to access, a stand-alone terrestrial 3D scanner is utilized for quick and detailed surveys.

DETAILED AS-BUILT

A reliable engineering plan of power plants, pipe and tunnel networks, and exploration sites that is suitable for end-to-end applications, such as day-to-day operations, inspection, and management, or purposes related to monitoring, rehabilitation, expansion and retrofitting, can be acquired through accurate detailing of the different elements of such critical areas. Three-dimensional (3D) laser scanning or Terrestrial LiDAR Surveying is a recommended method for inspection and documentation of infrastructures and facilities, which is capable of accurately and vividly recording all elements and features, down to every knot and bolt, tiny holes and cracks, protruding wires and metals.

ROUTE SURVEY

One of the most important LiDAR applications in power and energy in the Philippines is route surveying. It comprises all survey operations required for the design and construction of engineering works such as highways, railroads, pipelines, canals, or power lines.

TOWER SPOTTING FOR TRANSMISSION LINE

The efficient location of structures and detailing of the topography on the profile is an important component of the transmission line design. Restrictions, adequate clearances, accessibility, and other considerations are identified on the ground to arrive at the most economical alignment of transmission lines and the positioning of towers.
