"Drones enable firms to create highly-accurate maps and point clouds, discover costly job-site mistakes, and predict schedule delays, saving up to tens of thousands of pounds per week.”

That's the verdict ofRichard Clement, from Komatsu, on the value of using drones for mapping and surveying.

And he isn't alone.

Drone Mapping: A Guide (2)

Jim Gorrie, CEO Brasfield & Gorrie, says that drone mapping has helped to create a much more efficient process - taking weeks out of a schedule - whileMichael Lambert, VDC Manager at Chasco Constructors, believes that drone mapping data helps teams make 'better-informed decisions'.

Indeed, drone mapping has become an important process within UAS programmes, helping teams collect data quickly, accurately, and safely.

But what exactly is drone mapping and how can it benefit your industry application? And which drones and drone mapping software are best for the task?

Read this guide, which will cover the essentials of drone mapping.

What Is Drone Mapping?

Drone mapping is an aerial survey conducted by a drone and specialist cameras, which can include RGB (for photogrammetry), multispectral, thermal or LiDAR sensors.

Drone Mapping: A Guide (3)

This method enables the collection of highly-accurate data, extremely quickly. In fact, one piece of analysis showed that drone mapping collects data in excess of 90% faster than manual methods.

It is also a safer way of gathering data: No longer do you need to have staff walking over dangerous terrain or working at height - the drone can do it for you.

This data can be processed through drone mapping software to create a range of assets, such as 3D models, 2D maps, and digital elevation models, which can be used to extract valuable information like highly-accurate measurements and volumetric calculations.

Drone Mapping: A Guide (4)

This information helps with informed decision-making, provides valuable insights - including identifying mistakes or problems and, keeping up to date with the progress of a project - and streamlines effective communication with colleagues, stakeholders and the community.

Drone Mapping Outputs

Two of the most common types of drone mapping methods are photogrammetry and LiDAR.

Photogrammetry is the art of capturing high-resolution photographs to recreate a survey area. These images are processed and stitched together using sophisticated software to create realistic, geo-referenced, and measurable 3D models of the real world, as well as 2D maps.

Drone Mapping: A Guide (5)

LiDARworks by sending pulses of light to the earth's surface or a feature on it and measuring the time it takes to reflect back. LiDAR is particularly effective for detecting small objects during drone mapping, such as powerlines.

Drone Mapping: A Guide (6)

You can find out the difference between the two in our LiDAR vs Photogrammetry blog.

Drone mapping, including photogrammetry and LiDAR, can produce a variety of outputs to help surveyors and professionals in other industry applications gain vital insights.

2D Orthomosaic Drone Maps

A 2D orthomosaic is a top-down map of a survey site, or asset, built by stitching hundreds or thousands of digital photos - collected by the drone - together.

Drone Mapping: A Guide (7)

Drones and high-resolution cameras can help to build detailed, centimetre-accurate georeferenced maps.

These maps and pictures provide a real-world view, helping rapid decision-making and analysis of how a project is progressing.

3D Point Clouds

A point cloud dataset is a digital representation of the survey area or object. It is made up of thousands of points, with each being a geometric coordinate. When combined, they build a fleshed out 3D model. The more points collected, the denser the model.

Drone Mapping: A Guide (8)

Point clouds can provide a wealth of information, such as observations and measurements about an object’s depth, elevation, geometry, and location in space.

Point clouds tend to be generated by using 3D laser scanners and LiDAR, with each point representing a single laser scan measurement.

Drone Mapping: A Guide (9)

However, photogrammetry can also be used to build point clouds.

3D Mesh Maps

A 3D mesh is the evolution of a point cloud. Small triangles are created between the points and mapping software creates a texture to build a 3D mesh or model.

Drone Mapping: A Guide (10)

3D models are a great visual asset and are ideal for project monitoring and progress.

They can also be used to conduct

Digital Elevation Model Surface Models and Digital Terrain Models

Digital Elevation Models are a useful drone mapping output, providing elevation data of the survey area.

For instance, waste management company, SUEZ, took an orthomosaic data set captured from a Phantom 4 RTK and processed through ArcGIS Site Scan, to build this3D Digital Elevation Model to gather vital volumetric insights about this specific stockpile. Read the full blog here.

Drone Mapping: A Guide (11)

DEM models can include Digital Terrain Models (DTM) and Digital Surface Models (DSM).

The distinct difference between DTM and DSM is that DTM represent the bare earth (without any objects/buildings in it) to provide terrain data...

Drone Mapping: A Guide (12)

...while DSMrepresents the earth's surface and includes all objects on it.

Drone Mapping: A Guide (13)

LiDAR is particularly effective for DTM's, as its pulses can penetrategaps between leaves and branches to reach ground level and measure the terrain. Both LiDAR and photogrammetry can be used for DSM.

Drone ThermalMapping

Thermal drone mapping is a useful application, especially for monitoring assets in the oil and gas and utilities industries.

Drone Mapping: A Guide (14)

A thermal drone survey can identifyabnormal heat signatures - which can be missed with the naked eye. Thermal drone mapping can help identify heat loss, water leaks, or electrical faults.

Multispectral Mapping

Particularly useful for the agricultural industry,multispectral drone mapping can provide farmers with a wealth of information.

Drone mapping can generate vegetation indices to help visualise and understand crop health; orthomosaic maps can be created to monitor the evolution of crops; and fertiliser strategies can be formulated to improve overall productivity.

Drone Mapping: A Guide (15)

Drone Mapping Applications

Drone mapping has become so valuable, it is being used for land surveying, roof inspections, bridge/building surveys, infrastructure maintenance, and on construction sites.

Below is a breakdown of some of the most popular types of drone mapping applications.

Construction And Infrastructure

Drone mapping is an effective tool for the construction industry.

Maps and models can be created to monitor site progress, spot for mistakes or deviations from plans, measure stockpiles, and for rapid and highly-visual information sharing.

(Video) Drone Mapping Guide | Part 1

Drone Mapping: A Guide (16)

Drones enable construction professionals to collect this data safer than before, removing the need to clamber over dangerous stockpiles or access building sites.

Craig Matthews, Principal UAS Manager for Balfour Beatty, said: "Drones are a great tool to deliver the results safely, quickly and accurately. They remove people from harm's way, which is a big plus for us, and they give the project team and clients a unique view on the progress of a project that you couldn't get from the ground."

Real Estate

Drone mapping is extremely valuable to the real estate industry, providing buyers and sellers with low-cost, high-resolution, and frequently updated imagery.

Data such as boundary lines, trails, flood zones and topographic contours can be laid on top of the drone imagery for mapping.

Interactive 3D models can be a great feature for promoting a property.

Drone Mapping: A Guide (17)


Drone mapping is particularly valuable to the mining industry.

Detailed and up-to-date maps - which can be collected by regular drone surveys - can be used to manage stockpiles, water drainage, erosion detection, and pit and dump management among a host of other uses.

Drone Mapping: A Guide (18)

Andrew Carey, of Rio Tinto Kennecott Utah Copper, said: "We use DJI drones for a lot of mapping work, helping to improve decision-making and optimising inspections.

"Drones help the mining industry for a number of reasons, including increased safety, removing employees from hazardous areas, and increasing cost savings. We use drones for a range of operations, including reality modelling, asset management and drill/blast analysis."


Drone mapping is replacing the time-consuming process of farmers walking their fields.

Drone Mapping: A Guide (19)

Using UAVs to digitise agricultural land helps to maximise operational efficiency.

Drone mapping helps to monitor crop production and health, while irrigation and soil erosion can be managed through the creation of digital surface models.

You can read more about drone mapping for agriculture here.

Public Safety And Emergency Management

Drone mapping can be extremely useful for public safety agencies, for digitising a crime scene or for recreating the scene of a road-traffic collision, helping to get roads reopen quicker in the process.

Drone Mapping: A Guide (20)

Drone mapping is also highly valuable for emergency management: Enabling teams to safely and quickly access a disaster zone to collect unique aerial views for situational awareness, response planning and management, and to provide a true ands clear record to validate insurance claims.

For example, drones were used following the deadly Californian wildfires in 2018.

Drone Mapping: A Guide (21)

Commander Tom Madigan, of Alameda Country Sheriff's Office, said: "We used drones to take 10,000 photographs from low level and stitched them together into an orthomosaic map so the citizens who lived there and couldn't get back in could take a look at that map down to their street address and they could see what had happened to their property without going into a danger zone.

"We learnt that drone mapping was really important as part of an integrated emergency management strategy."

Land Surveying

Drone mapping is extremely beneficial to land surveyors.

Drones enable industry professionals to collectvast amounts ofdata which can be converted into3D topographic maps with contour data - eliminating a process which used to be extremely laborious.

Utilising RTK technology, land surveyors can use drones to create very accurate maps for their clients.
