AERIAL SURVEYING

Aerial Drone LiDAR and Photogrammetry Surveys

LandPlan offers advanced aerial survey services using drone-based LiDAR and high-resolution photogrammetry to deliver fast, accurate spatial data for engineering, land development, infrastructure, and environmental applications. Our aerial solutions reduce time on site while providing detailed 3D models, georeferenced maps, and measurable outputs to support design and planning processes.

From large terrain mapping to precision detail extraction, our drone teams are trained in flight planning, field operations, post-flight data processing, and GIS-based outputs — ensuring reliable, survey-grade results.

Our Aerial Survey Services Include:

• Flight Planning and Airspace Compliance
  Every project begins with accurate flight planning, airspace clearance (where applicable), and safety assessments to ensure full regulatory compliance and optimal flight coverage.

• Field Operation and Data Capture
  Our licensed drone pilots use LiDAR payloads or RTK-enabled photogrammetry platforms to collect high-density data, including terrain, infrastructure, vegetation, and built features.

• Post-Flight Data Processing
  We handle the full data processing workflow, including point cloud generation, image stitching, geo-referencing, and filtering — delivering clean, accurate datasets for professional use.

• Georectified Orthophotos
  High-resolution orthorectified imagery (orthophotos) tied to ground control points and local coordinate systems, ideal for planning, inspections, and GIS integration.

• Line Mapping and Feature Extraction
  Extraction of roads, building footprints, fences, contours, and utility features from orthophotos or point clouds — delivered in CAD or GIS-ready formats.

• Volumetric Calculations
  Rapid and accurate volume measurements of stockpiles, quarries, cut/fill areas, and landfill sites — ideal for monitoring material quantities and site progress.

• 3D Modelling and BIM Integration
  Generation of 3D surface models, terrain meshes, and scan-to-BIM outputs from aerial data, suitable for infrastructure design, landscape analysis, and architectural planning.

• GIS Mapping and Spatial Analysis
  Delivery of GIS-ready data formats for use in ArcGIS, QGIS, or AutoCAD Civil 3D, supporting overlays, spatial queries, and mapping applications.
  
  

Why Use Aerial LiDAR and Photogrammetry?

Aerial data capture allows for rapid surveying of large or inaccessible areas while maintaining high levels of accuracy and detail. It is ideal for projects involving:

• Earthworks and terrain analysis

• Infrastructure design and route planning

• Topographic base maps and contours

• Construction monitoring and progress tracking

• Environmental and agricultural mapping

• Quarry, landfill, or mine stockpile assessments
  
  

By combining LiDAR's ground-penetrating accuracy with photogrammetry’s visual clarity, we offer tailored solutions to suit the unique demands of every project.
