Aerial Survey & Mapping — Multirotor drone over terrain

Aerial Survey & Mapping

Fast, survey-grade photogrammetry for orthomosaics, DSM/DTM, contours and volumetrics — RTK/PPK workflows tied to ground control for engineering-ready CAD/GIS outputs.

RTK/PPK + GCPs Orthos • DSM/DTM Contours • Volumes

Survey-Grade Mapping at Speed

We plan autonomous grid and corridor flights to meet your accuracy and resolution targets, then process data through a control-first pipeline (RTK/PPK, GCPs, checkpoints). The result: orthomosaics, surfaces and contours you can trust for planning, design and measurement.

Ideal for construction sites, highways, mines, solar parks, estates and environmental monitoring — with clean handoff into CAD/GIS (DWG/DXF, GeoTIFF, LAS/LAZ).

  • Orthomosaics & Surfaces

    GeoTIFF orthos, DSM/DTM and hillshades aligned to your CRS.

  • Contours & Breaklines

    Clean linework, spot elevations and features for topo drawing.

  • Volumetrics

    Stockpile volumes, cut/fill and progress metrics with reports.

  • DGCA-Ready Safety

    Permissions, JSA, airspace checks/NOTAM (if required) and logs.

Flight & Processing Specs

Flights are planned to your GSD, altitude and overlap targets. We work in your CRS (EPSG) or site grid, and hand off tidy layers with legends and notes. Share any control, benchmarks and design surfaces to align outputs perfectly.

FAQ

Quick Answers

Key points on accuracy, permits and deliverables.

How accurate are the maps?

With GCP/PPK and checkpoints, typical planimetric/elevation accuracy is 2–5 cm. We include an RMSE summary and table.

Do you handle permits?

Yes—DGCA/airspace checks, site induction/JSA and NOTAM (if required). We maintain flight logs and safety records.

Can you do linear corridors?

Absolutely. We optimize legging, overlap and control for roads, transmission and pipelines.

LiDAR available?

Yes on request. For dense vegetation or fine terrain under canopy, LiDAR capture and classification are available.
