DRONE MAPPING
AND
DRONE INSPECTION SERVICES

​​

​

LiDAR (Light Detection and Ranging) uses laser pulses to measure distance between a sensor and the ground or surrounding objects. These measurements are combined into a precise three dimensional point cloud that represents terrain, vegetation, buildings, and infrastructure.

Unlike image based methods, LiDAR focuses on geometry rather than visual texture. This makes it especially useful for accurate measurement, elevation modeling, and analysis in low light or vegetation heavy environments.

​

KEY BENEFITS OF LIDAR

​

HIGH GEOMETRIC ACCURACY
LiDAR produces dense point clouds with consistent spacing and reliable elevation values. This makes it well suited for engineering, construction, and mapping workflows where measurement accuracy is critical.

​

VEGETATION FRIENDLY DATA CAPTURE
LiDAR laser pulses can often generate multiple returns, capturing information from canopy, understory, and ground. This allows for bare earth terrain modeling even in forested or overgrown areas.

​

LIGHTING INDEPENDENT OPERATION
LiDAR systems do not rely on sunlight or surface texture. Data can be captured in low light conditions without compromising accuracy.

​

Photogrammetry uses a series of overlapping photos to calculate the positions of points on the surface of the earth or objects. By analyzing two or more images of the same area from different angles, software can triangulate exact positions and generate 3D models, digital surfaces, and orthomosaic maps.

This method produces high resolution visual data and textured 3D models that are useful for measurement, analysis, and communication.

​

KEY BENEFITS OF PHOTOGRAMMETRY

​

HIGH RESOLUTION VISUALS
Photogrammetry captures true to life imagery that can be used to create detailed orthomosaic maps and photo textured 3D models. The results are visually rich and easy to interpret.

​

VERSATILE OUTPUTS
Data from photogrammetry can be used for a wide variety of applications, including site documentation, progress reporting, inspection, and integration with GIS and design tools.

​

FAST DATA COLLECTION
Because images can be captured quickly by drone, photogrammetry can be an efficient choice for measuring and documenting complex sites.

​

COST-EFFECTIVE
For many applications, photogrammetry delivers excellent visual context and spatial data without the additional cost of specialized scanning hardware.

​

WHEN TO USE PHOTOGRAMMETRY

​

SITE DOCUMENTATION AND VISUALIZATION
Photogrammetry is ideal for generating maps, orthomosaics, and textured 3D models for project documentation and visualization.

​

CONSTRUCTION PROGRESS MONITORING
Regular aerial imagery captures the real appearance of a project site over time. These images help stakeholders understand progress and identify potential issues.

​

INSPECTION AND CONDITION ASSESSMENT
Detailed aerial imagery can be used to inspect structures, roads, roofs, and other assets for damage, deformation, or wear.

​

MAPPING AND SURFACE MODELING
Photogrammetry creates high resolution digital surface models (DSM) that represent the visible surface of terrain, buildings, and objects. This data supports volume calculations, contour mapping, and site planning.

 

PHOTOGRAMMETRY VS LIDAR

​

Frequently Asked Questions​

​

What is the difference between drone inspection and drone mapping?
Drone inspection focuses on condition assessment and defect detection using photos video and thermal data. Drone mapping focuses on measurement and spatial accuracy producing maps models and surfaces that can be used in CAD GIS and engineering workflows.

​

What types of projects are best suited for drone mapping?
Common projects include construction site planning and progress tracking, land development, topographic surveys, volumetric stockpile measurements, corridor mapping, environmental monitoring, and infrastructure documentation.

​

What types of assets can be inspected with drones?
Typical assets include roofs and building envelopes, bridges, power lines and towers, pipelines and tanks, solar panels, wind turbines, industrial facilities, and telecommunication towers.

​

Do you offer thermal imaging and what is it used for?
Yes! Thermal imaging uses infrared sensors to detect temperature differences. It is commonly used for finding moisture intrusion, heat loss, electrical hotspots, and solar panel anomalies that may not be visible in standard photos.

​

When should I choose LiDAR instead of photogrammetry?
LiDAR is often the best choice when you need ground elevation under vegetation, when the terrain is complex, or when you need strong results in low texture areas. Photogrammetry is often ideal for open sites and produces excellent orthomosaics and textured 3D models.

​

How accurate are drone maps and models?
Accuracy depends on the workflow, flight altitude, sensor quality, and whether RTK and ground control points are used. Our data can achieve survey grade results when proper control and validation are included.

​

What is RTK and why does it matter?
RTK is a GPS correction method that improves drone positioning, helping deliver higher accuracy mapping and more repeatable results. It can reduce the amount of ground control needed in some projects.

​

Do I need ground control points?
Not always, but ground control points are recommended for many survey and engineering use cases, especially when you need the highest accuracy or independent validation. For lower tolerance work, RTK only workflows will be sufficient and still highly accurate.

​

What deliverables will I receive from a mapping project?
Common deliverables include orthomosaic maps, digital surface models and terrain models, contour lines, point clouds, 3D textured meshes, and CAD or GIS ready files such as GeoTIFF, LAS or LAZ, DXF, and PDF map outputs.

​

What deliverables will I receive from an inspection project?
Typical deliverables include annotated high resolution images, thermal images when applicable, video clips if needed, and a written inspection report summarizing findings, locations, and recommended next steps.

​

Can drone inspections be done without shutting down operations?
Often yes. Drone inspections can reduce disruptions compared with scaffolding, rope access, or lifts. Some sites may still require safety coordination, access control, or brief work area restrictions depending on risk.

​

How long does a typical drone inspection or mapping job take?
It depends on site size, complexity, and deliverables. Small inspections may be completed in a single visit. Larger mapping or LiDAR surveys may require more flight time and additional processing. Deliverable timelines depend on the scope and file types required.

​

What information do you need from me to quote a project?
We usually need the site location, the approximate area size, the asset types, the goal of the project, the deliverables you want, your accuracy requirements if any, and any site access or safety constraints.
