LiDAR Scanning & 3D Mapping

Precision LiDAR Scanning & 3D Mapping

Skyflex deploys airborne LiDAR (Light Detection and Ranging) systems to generate ultra-accurate 3D point clouds of terrain, structures, and infrastructure — delivering data that traditional survey methods simply cannot match in speed, safety, or resolution.

What Is Drone LiDAR?

LiDAR works by emitting thousands of laser pulses per second from a drone-mounted sensor. Each pulse reflects off the surface below and returns to the sensor, allowing us to calculate precise X, Y, Z coordinates for millions of points in a single flight. The result is a dense, georeferenced 3D point cloud with horizontal and vertical accuracy as tight as 1–5 cm.

Unlike photogrammetry, LiDAR penetrates vegetation, providing accurate ground models even through forest canopy — a critical advantage for utilities, pipeline corridors, and forested terrain.

Why Choose Skyflex for LiDAR?

Our pilots hold FAA Part 107 certification and operate the latest multi-return LiDAR sensors paired with high-accuracy GNSS/IMU systems. We process data in-house using industry-standard software (including LP360, Global Mapper, and ArcGIS), delivering publication-ready datasets — not just raw point clouds. We serve clients across Mississippi, Louisiana, Florida, Kansas, and nationwide for large corridor projects.

Faster. Safer. More Accurate.

A LiDAR drone survey can cover 200+ acres per flight, replacing weeks of ground-based survey work with hours of airborne data collection. No traffic control. No crew on dangerous slopes or near live power lines. No survey monuments disturbed.

SLAM LiDAR: Ground-Based & Interior 3D Scanning

In addition to aerial LiDAR, Skyflex UAS deploys SLAM LiDAR (Simultaneous Localization and Mapping) technology for environments where drones cannot safely or practically operate. SLAM LiDAR uses handheld or backpack-mounted laser scanning systems that build a precise 3D map of their surroundings in real time — without any reliance on GPS signals.

What Is SLAM LiDAR?

SLAM (Simultaneous Localization and Mapping) is a technique by which a scanning system continuously estimates its own position and orientation while building a 3D map of the environment around it. Unlike aerial LiDAR, which requires open sky for GPS, SLAM systems navigate entirely by referencing the geometry of their surroundings — making them ideal for GPS-denied spaces.

When SLAM LiDAR Is Used

SLAM ground scanning is deployed when the target environment is inaccessible or unsafe for aerial drones:

  • Building Interiors: Warehouses, factories, commercial spaces, historic structures, and any facility requiring accurate as-built floor plans or 3D documentation.
  • Underground Environments: Tunnels, mines, underground utility vaults, and subsurface infrastructure where GPS is entirely unavailable.
  • Parking Structures: Multi-level enclosed garages where ceiling height and structural obstructions prevent safe drone flight.
  • Dense Forest Understory: Areas where canopy closure and terrain complexity make safe drone flight impractical but ground-level 3D capture is needed.
  • Confined Spaces: Tanks, silos, culverts, and similar enclosures requiring interior dimensional documentation.

How SLAM Complements Aerial LiDAR

Aerial LiDAR excels at capturing above-ground terrain, roof geometry, and above-canopy features — but it cannot see inside structures or capture ground-level detail in areas blocked by overhangs, dense vegetation, or structural obstruction. SLAM ground scanning fills these gaps by capturing interior and below-canopy geometry that aerial data misses. When combined, aerial and SLAM datasets are co-registered into a single, seamless point cloud that provides a complete 3D model of both the exterior and interior of a site — an invaluable resource for BIM, digital twin development, renovation planning, and as-built documentation.

SLAM LiDAR Deliverables

SLAM ground scanning produces the same high-quality deliverables as aerial LiDAR collection:

  • Point Cloud files (.LAS / .LAZ)
  • As-built floor plans and section cuts
  • 3D mesh models and BIM-ready geometry
  • Digital Elevation Models (DEM) for ground-level surfaces
  • Dimensional documentation for engineering and construction

Ideal Applications

SLAM LiDAR is particularly well-suited for: building interiors requiring as-built documentation, tunnel and mine surveys, underground infrastructure mapping, historic preservation and heritage documentation, and any project requiring complete interior-to-exterior 3D capture when combined with aerial collection.

Complete LiDAR Deliverable Suite

Skyflex UAS produces a comprehensive range of LiDAR deliverables tailored to each client’s project requirements. Standard deliverables include:

  • Point Cloud (.LAS / .LAZ): The raw 3D dataset from which all other products are derived, classified by surface type.
  • DEM (Digital Elevation Model): Gridded representation of terrain or surface elevation.
  • DSM (Digital Surface Model): Elevation model including all above-ground features — buildings, vegetation, structures.
  • DTM (Digital Terrain Model): Bare earth terrain model enhanced with breaklines, ridgelines, and stream channels.
  • Bare Earth Model: Ground-only surface with all above-ground objects removed through classification.
  • Contour Lines: Vector contour lines at client-specified intervals derived from the DTM or DEM.
  • TIN (Triangulated Irregular Network): Vector terrain model preserving breaklines and mass points for engineering design.
  • Orthomosaic: Geometrically corrected, georeferenced aerial image mosaic aligned with LiDAR data.
  • Hillshade Map: Shaded relief visualization of terrain for visual interpretation and presentation.
  • Slope Map: Raster representation of terrain steepness derived from the DTM.
  • Slope Direction (Aspect) Map: Raster showing the compass direction each slope face is oriented toward.
  • Intensity / NIR Image: Grayscale or false-color image derived from LiDAR return intensity values.
  • Canopy Height Model (CHM): Raster representing vegetation height above the bare ground surface.
  • Vegetation Density Model: Raster representing the density of vegetation returns within a defined height range, useful for forest inventory and habitat assessment.
  • Surface Roughness Model: Raster quantifying local terrain texture variation, used in geomorphological analysis, trafficability studies, and habitat characterization.

Custom deliverable formats and coordinate reference systems (CRS) are available upon request. Contact us to discuss your project’s specific output requirements.

Right of Way (ROW) Corridor Surveys

LiDAR is the gold standard for right-of-way corridor surveys because it can simultaneously classify every return — separating ground, vegetation, structures, and conductors into individual layers. This classification capability makes it possible to analyze vegetation encroachment, conductor position, terrain, and structural data from a single flight mission.

Skyflex flies full corridor lengths and delivers a comprehensive data package for utility and infrastructure ROW management:

  • Classified point cloud for the entire ROW width, with ground, vegetation, structure, and conductor layers separated
  • Vegetation encroachment reports identifying trees and branches within defined clearance zones
  • Conductor and structure position data for sag analysis and compliance reporting
  • Terrain models for new line routing and design feasibility
  • Cross-sections generated at any interval along the corridor
  • Encroachment detection reports flagging unauthorized structures, equipment, or new construction within ROW boundaries
  • Compatible with utility GIS platforms and asset management systems (ESRI, AutoCAD, and major utility platforms)

Applications

Electric transmission and distribution ROW, pipeline corridors, railroad right of way, highway vegetation and clearance surveys, and gas pipeline ROW management programs.
