Topography and LiDAR
At Tecnoseg SpA, we combine GNSS RTK, robotic total stations, aerial and terrestrial LiDAR, satellite imagery and UAV photogrammetry in traceable digital workflows, integrating each data point in a validated and traceable digital flow.
We guarantee centimetric precision, field efficiency and results ready for engineering, mining and public works. Tecnoseg Topography — Precision that builds trust.
What do we do?
We apply a comprehensive topographic methodology that combines terrestrial and aerial instrumentation with geodetic control and advanced digital processing.
We transform terrain data into precise, traceable information ready for engineering, planning or construction control, ensuring coherence between field, office and final design.
Centimetric precision for large-scale projects.
Our main services
High-density point cloud acquisition using LiDAR sensors mounted on UAV drones. They allow modeling of natural terrain, vegetation and structures with millimetric precision, even in hard-to-reach areas or with dense coverage.
Mobile and stationary laser scanning to model surfaces, tunnels, interiors or structures with three-dimensional detail. SLAM technology allows data capture in complex environments without requiring direct line of sight, generating precise and georeferenced 3D models.
Field data capture using GNSS and total station to generate base plans, contour lines and digital terrain models with guaranteed precision.
Positioning and verification of construction elements, ensuring agreement between design and execution.
Calculation of earthwork volumes, piles or stockpiles, integrating UAV data and terrestrial measurements for verifiable results.
Post-construction surveys to validate the location and dimensions of works, installations or utility networks.
Implementation of GNSS networks and control points linked to official frameworks, ensuring coherence and traceability.
Stability control in dams, slopes and structures through high-accuracy differential leveling.
Our process
Nuestro proceso incluye:
Technical planning and field coordination: We define the survey scope, reference systems and most efficient capture methodology according to terrain and project objectives. Control points, routes and observation zones are established, ensuring geodetic coherence from the start.
Equipment installation and calibration: We configure total stations, GNSS RTK and LiDAR sensors according to required tolerances. Each piece of equipment is calibrated in the field and validated with independent control points to ensure centimetric precision.
Topographic and geospatial data capture: We perform field surveys using GNSS observations, laser scanning or UAV photogrammetry, as appropriate. All records are georeferenced in real time and documented for complete traceability.
Processing, validation and quality control (QA/QC): Data is processed in specialized software (Topcon Magnet, Trimble Business Center, LiDAR360, Pix4D, among others), applying filters, corrections and network adjustments. Results are validated through cross-control comparisons and positional accuracy verification.
Product delivery and technical review with client: We deliver plans, digital models, contour lines, point clouds and control reports, compatible with CAD, GIS and BIM. We include a technical review session where results and field observations are validated.
