Mobile Mapping: A game-changing solution for quick and accurate survey data collection

March 20, 2023

Mobile mapping is a rapidly evolving technology that enables data capturing and visualisation in real time. It allows for the collection of accurate, engineering-grade survey data at a much faster rate than traditional methods, making it an ideal solution for a variety of applications, including transportation, utilities, infrastructure, and construction.

In this blog, Sensat's Head of Survey Solutions, George Dey uncovers the benefits of mobile mapping, its uses, and the technology behind it.

What is Mobile Mapping?

Mobile mapping is a method of data capturing that utilises advanced technology to gather information about the environment, including streets, buildings, and other structures. It involves the use of a mobile mapping system, which is typically mounted on a vehicle and consists of various sensors and cameras.

The system captures data as it moves through the environment, using sensors to measure distances, angles, and other attributes. The data is then processed to create a 3D model of the environment, which can be used for a variety of applications, including surveying, asset management, and planning.

Benefits of Mobile Mapping


One of the biggest advantages of mobile mapping is its speed. Traditional surveying methods can be time-consuming and labour-intensive, requiring teams of surveyors to spend hours or even days in the field. With mobile mapping, data can be captured at a much faster rate, reducing the time and cost of surveys.


Mobile Mapping can capture engineering-grade data without the risk of human error.  The use of advanced sensors and cameras allows for precise measurements and the creation of detailed 3D models that can be used for a variety of applications.


Another benefit of mobile mapping is its versatility. It can be used for a wide range of applications, from transportation planning to infrastructure management. It is particularly useful for large-scale projects that require detailed data capturing over a wide area.

Uses of Mobile Mapping

Mobile mapping technology has a wide range of applications in industries. By providing detailed data and visual representations of the environment, it allows for better decision-making, planning, and management of resources.

  • Transportation Planning: Mobile mapping can be used to capture data on road conditions, traffic patterns, and infrastructure. This data can be used to inform transportation planning and improve safety on the roads.
  • Utilities: Mobile mapping can be used to map the location of utility infrastructure, such as gas pipelines, water mains, and power lines. This information can be used to improve maintenance and repair operations.
  • Construction: Mobile mapping can be used to create detailed 3D models of construction sites, enabling builders to visualise the project and identify potential issues before construction begins.
  • Asset Management: Mobile mapping can be used to create detailed inventories of assets, such as buildings, roads, and bridges. This information can be used to plan maintenance and repair operations and allocate resources more efficiently.

The technology behind Mobile Mapping

Mobile mapping systems typically consist of a variety of sensors and cameras that work together to capture data and process it. Here are some of the key components of a mobile mapping system:

LiDAR: LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser beams to measure distances. It is commonly used in mobile mapping systems to create precise 3D models of the environment.

GPS: GPS (Global Positioning System) is a satellite-based navigation system that can be used to determine the location of a mobile mapping system.

Cameras: Cameras are used to capture images of the environment, which can be used to create a visual record of the survey area.

IMU: An IMU (Inertial Measurement Unit) is used to measure the orientation and acceleration of a mobile mapping system. This information is used to determine the position and orientation of the system as it moves through the environment.

In conclusion, mobile mapping is a game-changing technology that provides fast, accurate, and engineering-grade survey data. Its benefits include its speed, accuracy, versatility, and the ability to capture data on a large scale. As the technology continues to evolve, we can expect to see more applications for mobile mapping and an even greater impact on industries that rely on accurate and efficient survey data collection.
