As a leading company for topographic map survey of India, BPC INDIA possesses expertise to create 3D models of engineering structures and objects, digital plans, digital elevation models, and high quality maps at any scale.

Topological survey is used for creating topological mapping, and such mapping is required for every engineering design or construction. Topographic Road Survey aims to create geological symbols that reflect surface facilities, underground, and natural objects. It further includes presence of possible building and communication lines on the requested territory.

At BPC INDIA, we have always embraced technological innovations. With modern DGPS (Differential Global Positioning System), we conduct topographical survey in a short time and low cost. As a DGPS survey company we use a network of fixed and ground-based reference stations to broadcast the difference between the positions indicated by the GPS satellite systems.

The accuracy of the known fixed positions is near about 5 cm. The differences between satellite pseudo-ring and actual pseudo-ring can be determined through the broadcast stations. It helps the receiving stations to correct their pseudo-rings. The digital correction signal is broadcasted locally over ground-based transmitters of shorter range.

BPC INDIA is poised with immense experience of carrying topographic survey and mapping projects for many eminent companies belonging to different industries.

Topographical mapping for inventory, land use and cadastral works
Land use with a view of cadastral registration of the land plots occupied along the roads
Preparation of the documents for property right registration
Orthophoto maps of 1:2000 scale at plants
Digital ground model (DGM) as laser reflection points
Digital air photos including oblique ones
Modeling true relief (ground surface) under canopy in any season. Detailed topographic plans and maps of territories without landmarks (tundra, completely snow covered areas, deserts, sand beaches, etc.)
Using oblique imagery allows creating photorealistic digital surface. This feature is mostly useful for modelling of city territories and complex infrastructure.
Terrestrial laser scanning technology allows modelling engineering facilities of complicated structures with very high levels of accuracy.
3D - three dimensional (have XYZ coordinates which allow three dimensional positioning due to immediate and simultaneous data acquisition by on-board GPS receiver and GPS receivers based on the ground stations, Coordinate-referenced
Full service on surveying of any scope in the shortest time;
Ability to conduct the works in any part of the world

Our Infrastructure

We deploy application of the state-of-the-art and highly proficient technologies for terrain and 3D aerial scanning for topographic survey by drones. Along with digital aerial photography, we can also provide flawless bathymetry data.
