Every plot,preciselysurveyed.
A Differential GPS survey gives you centimetre-level ground truth before a single brick is laid — accurate boundaries, contours and levels captured with dual-frequency GNSS equipment. TNC Architects delivers CAD-ready survey drawings that feed directly into your architectural and structural design.
Centimetre accuracy for every plot
Our DGPS surveys use a fixed base station and roving GNSS receiver working together to correct satellite positioning errors in real time — delivering boundary, contour and elevation data accurate enough for legal demarcation, architectural planning and construction layout.
Everything included in every project
DGPS base station established over a known reference point, with control points tied to the WGS84 datum for site-wide coordinate accuracy.
Dense ground-level shots captured across the site to generate contour lines and a digital terrain model at the intervals your project needs.
Precise plot boundary marking with area calculation and encroachment identification, cross-verified against revenue and Jamabandi records.
Final output delivered as AutoCAD DWG/DXF drawings with a live coordinate grid — ready to feed straight into layout and structural planning.
Step by step to perfection
Preliminary site visit to identify existing reference points, plot extent and access — the groundwork for an accurate survey.
DGPS base station fixed over a known control point while the rover unit walks the site, logging every boundary corner and ground shot.
Raw GNSS data post-processed into WGS84 / local grid coordinates, generating the terrain model and contour lines.
Final CAD drawings, area statement and survey report delivered — ready to move straight into architectural design.
