GEODETIC SURVEYING
The science that deals with the measurement of the Earth
CONTROL SURVEY
Establishment of survey controls or reference stations to be used in the measurement of details on the Earth’s surface. With the use of GPS (Glopal Positioning System) Satellite Receivers and Electronic Total Stations.
TOPOGRAPHIC SURVEY
The measurement of the topographic details on the surface of the earth on each specific location.
The survey is done using the Electronic Total Station, an instrument with a Theodolite that measures the horizontal and vertical angles, an Electronic Distance Meter that measures the distance from the location the station occupies to every object (house, fence, power line, tree, bridge, river, road,etc.), an Electronic Field Book that records all the measurements, and a Mini Computer that calculates all the necessary measurements from the observed data.
HYDROGRAPHIC SURVEY
The measurement of the surface of the earth under any body of water.
The survey is done using an Electronic Total Station or GPS, to measure the location and echoi sounder or sounding rope to measure the depth of water up to the bottom surface of the river or any body of water.
ROUTE SURVEY
The measurement of the plan, longitudinal and cross-sectional detail of the proposed route of the road, transmission lines, pipelines, and other related undertaking.
PARCELLARY SURVEY
The measurement of lots and the area bounded by their specific limits/boundaries on a certain location on the surface of the earth.
SUBDIVISION SURVEY
The process of dividing a particular lot into specified number of lots with specific areas.
The job is done using computer and software in the preparation of subdivision plan.
The location of the lot corners is set on the ground using Electronic Total Stations with reference to survey controls and marked on the ground with LMB Concrete Monument.
GEOLOGIC INVESTIGATION
The measurement of the properties and characteristics on and under the surface of the Earth on every particular area.
The type of soil, rocks, or rock formation and the stability and bearing capacity.
The job is done by getting samples on site using standard tools, and drilling machines to extract sample of materials for laboratory analysis.
