Drone Surveying & Aerial Mapping

Advanced Drone Surveying Combined with Professional Ground Surveying

Kennedy Surveying & Engineering Ltd. (KSEL) provides professional drone surveying, aerial mapping and geospatial services for construction, engineering, development and land surveying projects throughout Ireland.

Our approach combines modern UAV technology with established surveying methods, including RTK GNSS/GPS, robotic Total Station and terrestrial surveying techniques. This allows KSEL to capture large areas efficiently from the air while establishing and verifying

critical survey information from the ground.

The result is a comprehensive survey solution capable of producing accurate, detailed and practical information for engineers, architects, contractors, developers and design teams.

Drone + GPS + Total Station

A Complete Surveying Solution

A drone is an extremely powerful data-capture platform, but KSEL does not rely on aerial data alone where ground verification or conventional survey observations are required.

Our drone surveys can be integrated with RTK GNSS/GPS and Total Station observations to establish survey control, verify critical

features and capture areas that may not be suitable for photogrammetric measurement.

This combined approach provides the efficiency of aerial surveying together with the control and versatility of traditional land surveying.

It is particularly valuable on construction and development projects where clients require more than an aerial image — they require

survey information that can be incorporated directly into their engineering and design workflow.

Topographical Surveys

Drone surveying enables KSEL to capture extensive site information efficiently, particularly across large or difficult-to-access areas.

Aerial survey data can be combined with ground observations to produce detailed topographical information including:

• Existing ground levels

• Buildings and structures

• Roads and hardstanding

• Kerbs and footpaths

• Walls and boundaries

• Drainage features

• Site infrastructure

• Contours

• Ground surfaces

• Existing site features

Survey information can then be processed and prepared for use by architects, engineers and design teams.

High-Resolution Orthomosaic Mapping

Drone imagery can be processed to produce a high-resolution, geometrically corrected aerial image of a site.

Unlike a standard aerial photograph, an orthomosaic provides a consistent plan-view representation that can be used alongside CAD

and survey information.

This provides clients with an extremely useful visual record of existing site conditions and can assist with design coordination, planning, construction monitoring and project documentation.

3D Point Clouds & Digital Terrain Models

Drone photogrammetry allows thousands of overlapping aerial photographs to be processed into detailed three-dimensional survey datasets.

KSEL can generate:

3D Point Clouds
Dense three-dimensional representations of the surveyed site containing millions of measured points.

Digital Surface Models (DSM)
Detailed models representing the visible surface of the site, including buildings, vegetation and other features.

Digital Terrain Models (DTM)
Ground models developed for engineering, contouring, earthworks and site analysis applications where appropriate.

These datasets can be integrated with conventional survey information and used to develop engineering drawings and 3D site models.

Earthworks & Volume Surveys

Drone surveying is particularly effective for monitoring earthworks and calculating material quantities across construction sites.

KSEL can provide surveys for:

• Stockpile volumes

• Excavation quantities

• Cut-and-fill analysis

• Existing versus proposed surface comparisons

• Bulk earthworks monitoring

• Material movement assessment

• Periodic site volume surveys

Repeated drone surveys also provide an efficient method of recording how a site changes throughout the construction programme.

Construction Progress Monitoring

KSEL can undertake scheduled drone surveys throughout a project to create an accurate visual record of construction progress.

Regular aerial surveys can assist contractors and project teams with:

• Progress reporting

• Client presentations

• Site coordination

• Programme reviews

• Recording completed works

• Comparing different stages of construction

• Documenting site conditions

• Marketing and project photography

The combination of aerial imagery and survey data provides project teams with a clear overview of the entire development.

Difficult & Inaccessible Areas

Drone surveying can significantly reduce the requirement for personnel to physically access difficult, elevated or potentially hazardous areas.

Subject to site conditions and operational requirements, UAV technology can assist with surveying and inspecting:

• Roofs

• Building façades

• Large structures

• Embankments

• Quarries

• Earthworks

• Large development sites

• Difficult terrain

• Areas with restricted ground access

• Data Structures

This can improve data collection efficiency while reducing unnecessary exposure of survey personnel to difficult working environments.

Professional Survey Deliverables

Depending on project requirements, KSEL can provide survey information in a range of formats suitable for construction and design teams, including:

• AutoCAD DWG/DXF drawings

• Civil 3D surfaces

• 3D point clouds

• LAS point cloud data

• Orthomosaic imagery

• Digital Terrain Models

• Digital Surface Models

• Contour drawings

• PDF survey drawings

• Volume and earthworks information

• 3D site models

Deliverables can be tailored to suit the requirements of the client's engineer, architect, contractor or design team.

Why Use KSEL?

KSEL brings together surveying, engineering and modern geospatial technology within one service.

Rather than providing drone imagery in isolation, we understand how survey information is used during the design and construction process.

Our capabilities combine:

Drone Surveying + RTK GNSS/GPS + Total Station Surveying + Laser Scanning + AutoCAD + Civil 3D+Trimble Business Center + DJI Terra

This allows KSEL to select the most appropriate survey method — or combination of methods — for each individual project.

From a small development site to a large construction project, our objective is simple:

Capture accurate information efficiently and deliver it in a format that our clients can immediately use.
