Topographical & Engineering Surveying
Millimeter-grade 3D elevation models, contour lines, and physical feature mapping. We align baseline reference loops directly to Survey of Bangladesh Geodetic control points for maximum accuracy.
Technical Overview & Standard Operating Procedure
Topographical and engineering surveys form the foundational backbone for all civil engineering, mega infrastructure, and industrial developments. Our team deploys multi-frequency RTK GNSS receivers coupled with Leica total stations to map exact terrain contours, physical boundaries, utilities, and ground features.
Execution Methodology & Equipment Calibration
We establish physical geodetic control networks anchored to SOB (Survey of Bangladesh) primary datum monuments. Using precise leveling loops and reflectorless laser electronic total stations, we record millions of physical coordinate observations.
