Absolute Spatial Certainty Before Architecture Begins
Inaccurate boundary measurements and faulty contour elevations are the leading cause of costly construction disputes, boundary litigations, and failed drainage networks. Relying on outdated manual chains or verbal seller assurances is an unacceptable risk for serious developers.
Baasthan's Survey & Mapping division equips developers, landowners, and civil engineers with absolute mathematical certainty. We utilize multi-frequency Differential GPS (DGPS) linked to permanent satellite networks, supplemented by laser-guided Electronic Total Stations.
Our RTK drone photogrammetry generates high-density digital elevation models (DEM), allowing architects to calculate precise cut-and-fill soil volumes and design gravity-assisted storm drainage networks.

Frequently Asked Questions
What is the difference between an ordinary survey and a DGPS survey?
Traditional surveys using manual tapes or optical levels suffer from accumulated human error over large distances. A DGPS survey connects to multiple satellite constellations simultaneously to provide sub-centimeter absolute global accuracy.
Can you map land covered in dense vegetation or waterbodies?
Yes. We combine multi-frequency satellite DGPS, total station line-clearing surveys, and specialized drone flight patterns to accurately map even heavily forested or marshy land tracts.
How fast can you survey a 20-acre land parcel?
Field data capture for a 20-acre tract typically takes 1 to 2 days, with complete processed CAD contour drawings and orthophoto maps delivered within 48 to 72 hours.
