Johannesburg Infrastructure GPR Scan
Prior to launching a multi-million Rand commercial office excavation, the construction company required verified mapping of historical underground services. TerraX3D surveyed the site using dual-frequency GPR and electromagnetic locators.
Data Pipeline:
Output: Identified a high-voltage electrical cable feed and a municipal water main buried 1.2m deep that were completely omitted from historical site blueprint databases, preventing critical utility strike shutdowns.
Limpopo Utility Transmission Line LiDAR
TerraX3D was commissioned to scan a 15km transmission line corridor passing through dense bushveld. We deployed drone-mounted LiDAR to analyze exact tree canopy proximity and evaluate cable sag parameters under thermal stress.
Data Pipeline:
Output: Identified three critical vegetation encroachment zones and verified sub-millimetric tower tilt. Data was provided to engineers as a classified LAS point cloud file and digital elevation models (DEM).
Mpumalanga Coal Mine Stockpile Calculation
A large-scale coal mining operation required weekly volumetric updates of stock piles to audit inventory. We conducted drone volumetric surveys using RTK GNSS receivers to establish precise boundary bases.
Data Pipeline:
Output: Processed stockpile volumes within 24 hours of flight. Volumetric data matched weightbridge inventory with under 1.2% absolute deviation, removing the need for manual surveyor pile climbing.
