Drone Mapping


Drones are the perfect solutions for aerial mapping. With a drone, It is possible to carry out topographic surveys with highly accurate measurements and faster than traditional land surveying methods. Drone mapping is even widely helpful in complex or difficult to access environments where human movement is a great challenge. With the combination of drones and high-resolution cameras enables the mapping industry at levels of details never before imagined. The Salem Land Surveyors is the first land surveying company implements drone mapping in Coimbatore. Get unimaginable topographic data with unbelievable accuracy.


Control Network Establishment


Key to success! The control network establishment survey is a tedious and important process to identify the benchmark position of any particular region or project extents. The Salem Land Surveyors with the help of DGPS instruments (Differential Global Positioning System) and technology identifies the key referential benchmark point with data accuracy. The benchmark is the common trustworthy coordinate point important for any project success from the project planning, design, construction, to documentation phases. As the accuracy in bench marking the project coordinate is the key success to any project, we suggest our clients identify the project coordinate before project commencement to minimize the cost of reworks. Accurate in the benchmark positioning!


Earth Work Volume Calculation


The hardship of volumes! Earthwork is a tremendous job that involves huge manpower, planning and public support. Earthworks include road works, highways, irrigation like canals, dams, land grading, etc. Biding of earthwork contracts revolves around the accurate data information on the land extent, usage, and planning extent that lead to substantial overhead costing. The Salem Land Surveyors help them to scale up the surface area to any stretchable extent using total station, auto levels or Real Time Kinematic (RTK) system to drone according to the specification/need and provide accurate information with details. Helpline for tough times on volumes!

Pile Marking

Pile Marking is based on the topographical survey of the land, lay out design drawing is prepared comprising roads, plots and allotting commercial spaces, public use space, etc as required by government norms. On approval of the layout design drawing by the concerned authorities and the clients, the concerned layout design is being marked at respective site as directed and guided by the site engineer of the client.Pile Marking is carried out by using Total Station Survey Instrument.

Leveling Marking

Levelling The art of determining the relative heights of different points on or below the surface of the earth is known as leveling. Thus, leveling deals with measurements in the vertical plane.To prepare a contour map for fixing sites for reservoirs, dams, barrages, etc., and to fix the alignment of roads, railways, irrigation canals, and so on.Level surface Any surface parallel to the mean spheroidal surface of the earth is said to be a level surface. Such a surface is obviously curved. The water surface of a still lake is also considered to be a level surface.

Road Marking

After primary investigation regarding the justification of constructing a new road, the tentative alignment or alignments are marked on the general map and contour map of the area through which it is expected to pass. While marking the tentative alignment, the following points should be considered.The proposed road should connect a sufficient number of villages, towns, industrial places, places of religious importance,The alignment should be taken in such a way that unnecessary cutting can be avoided.

Any Shape Building Marking

A building is set out in order to clearly define the outline of excavation and the Centre lines of the walls, so that construction can be carried out exactly according to plan. The centre line method of setting out is generally preferred and adopted.Locating the center line, usually marked by stakes at 100-ft intervals called stations. Determining elevations along and across the center line for plotting profile and cross sections.Computing the volumes of earthwork and preparing a mass diagram.Locating right-of-way boundaries, as well as staking out fence lines.

Layout Marking

layout Marking means the process of transferring a design or pattern to a workpiece, as the first step in the manufacturing process.[1] It is performed in many industries or hobbies although in the repetition industries the machine’s initial setup is designed to remove the need to mark out every individual.On approval of the layout design drawing by the concerned authorities and the clients, the concerned layout design is being marked at respective site as directed and guided by the site engineer of the client.

Boundary Line Marking

The boundary line marking is being carried out on the landed property of a vast area, or wherever required by the Clients, through GPS (Global Positioning System). After arriving at the latitude and longitude coordinates of the location of the relevant site using GPS (Global Positioning System) Instrument, through satellite UTM (Universal Traverse Mercator), the Co-ordinates of X Axis and Y Axis of the Site would be arrived at. The Datum (i.e. Latitude/Longitude) would be fixed on any Permanent Location at the site. Based on the above datum, the Boundary Survey of the site.
