How Advancements In Day To Day Technology Helping In Business Productivity

May 26, 2023

Traditional surveying needs physical measurements and inputs and might take many days or weeks, depending on a site's size, topography, and visibility. Drone technology, as a solution, may make surveying a lot simpler and more precise, allowing you to save time and take on more clients.

Compared to traditional surveying methods, surveying with drones is necessary for establishing your firm for success. This article will teach you about drone surveys and how they may help your business.

What Is Drone Surveying?

Drone surveying is collecting airborne data with drones or unmanned aerial vehicles (UAVs) equipped with downward-facing sensors such as light detection and ranging (LiDAR) payloads, multispectral cameras, and RGB cameras.

  • Multispectral cameras: Multispectral cameras work by photographing several wavelengths of light. They are used in remote sensing to investigate land use, land cover change, vegetation, and other topics. They offer surveyors detailed insight and improved target discrimination.
  • UAV: A UAV is an airplane that can be steered autonomously or remotely by people utilizing software-controlled flying plants incorporated into the system. In other words, there is no human pilot on board the airplane. UAVs use a global positioning system (GPS) and inbuilt sensors to navigate.
  • RGB cameras: Instead of multispectral cameras, RGB cameras catch the same wavelengths of light as the human eye. These are everyday cameras that people use to snap pictures.
  • LiDAR: LiDAR is a well-known remote sensing technique for precisely measuring the distance between objects on Earth's surface. It is utilized in various industries, including construction, mining, agriculture, etc.

Benefits Of Using Drones In Surveying

Drone land surveying offers various advantages. It mostly streamlines operations, but let's go further to see how employing drones for surveying might alter your business.

Maps Complex Regions

Surveyors and contractors face several physical challenges, including varied terrain, steep hills, and inaccessible regions. Previously, these constraints might render surveying difficult or imprecise.

However, drone land surveying allows access to inaccessible locations while providing precise data. Drones will fly over all those obstacles, eliminating the need to send workers with a backup crew.

Improved Safety Standards

Work in the construction industry, for example, can be hazardous. Traditional surveying frequently involves employees approaching difficult-to-reach areas on construction sites using heavy machines.

On the other hand, a drone survey flight can be conducted safely on the site without exposing workers to hazardous areas. Drone surveying is beneficial not only for worker safety, but the exact data acquired can be utilized to identify possible hazards on the job site before they cause problems.

Saves Cost and Time

Companies that recognize the importance of client services and consumer satisfaction understand that time is of the essence. Traditional topographic survey methods can take many days or weeks to complete, especially when dealing with vast land areas.

Finally, manual survey methods are time and labor expensive. However, drone surveying bridges this productivity gap while assuring precision and accuracy. Modern UAVs can perform multiple workers' tasks in a short time.

Enhanced Documentation And Faster Reconciliation

You will likely need to check various documents when surveying a site. Finding information can be difficult, especially when it is urgent. Furthermore, tracking operational faults is sometimes impossible when using typical surveying methods.

At regular intervals during the construction process, drone data provides organized, accurate, detailed, and retrievable documentation. You can review full procedures and discover error phases with comprehensive information.

Furthermore, the data can increase team performance and structural accuracy through training.

Improved Efficiency

Drone surveying enables accurate mapping and measuring of civil building projects, avoiding the need for more expensive and time-consuming manual surveying. Contractors can swiftly and efficiently collect and analyze data in real-time using drones, allowing them to make educated project decisions.

Work is typically done in multiple areas on a building site, making it difficult to track what has changed. Larger construction sites take numerous work days to hand survey, and the site can change dramatically during that period, rendering the data unreliable.

The timely data from drone surveying helps construction businesses complete their projects on time and within budget.

Comprehensive and Accurate Data

Survey drones generate highly accurate aerial data. The method uses GPS points to create complete and precise maps over enormous land areas in a single drone flight. Surveyors can measure distances, elevations, surfaces, and volumes without introducing human error.

You can use the data to make drawings, 3D point clouds, 2D figures, etc. Photogrammetry software can assist you in creating digital surface models (DSMs) and digital terrain models (DTMs) for better understanding.

Furthermore, the data is provided in various forms, which may be required for comparison and auditing purposes.

Drone surveys also allow you to collect necessary details that you might otherwise overlook. There is no need to return to the spot to collect the data because the drone has taken care of that. Such data could be critical in development because it can affect land elevation or construction.

How Drone Surveying Works

Drones used for surveying include integrated cameras that take photographs of the ground from various places in the air. Images are geo-tagged with geo-coordinates collected by a GNSS sensor on the drone, indicating where the image is in space. The image is "fact-checked" against known spots on the ground using RTK or PPK processing.

A single drone flight captures hundreds, if not thousands, of photographs, which are then processed with photogrammetry software, which "stitches" the images together to create geo-referenced orthomosaics or 3D models of a work site.

These three-dimensional maps can then be studied to provide specific information regarding project quantities, distances, elevations, and inventory. Companies may reliably and accurately track changes and progress by regularly gathering this data and comparing those maps to design files and earlier surveys.

Because drones can fly at considerably lower altitudes than human planes or satellites, they can collect highly detailed data faster and at a lesser cost than a base and rover. Drones can also capture aerial photographs from terrain that would be too risky for a human to explore on foot.


Drone technology has transformed how the heavy civil and earthworks sectors survey their job sites. Unmanned aerial vehicles (UAVs) provide faster and less expensive surveying while maintaining accuracy. They require little additional training and education to operate, allowing you to collect data as frequently as you like—without putting your personnel in danger, lowering safety concerns.

With drones becoming more affordable and commonplace jobsite tools, collecting more frequent and precise site data is easier than ever.

Having up-to-date site data also means recognizing problems before they become costly or necessitate rework. It entails more stringent planning, budgeting, and improved contractor management. Significantly, drone-captured survey data can improve team accountability, communication, and collaboration when properly handled.
