Mobile Mapping and Geospatial Data

Mobile mapping is the process of collecting geospatial data using a moving vehicle fitted with a range of remote sensing technologies. Digiflec's mobile mapping service is a highly accurate, efficient and cost-effective survey method.

Mobile mapping is the process of collecting geospatial data using a moving vehicle fitted with a range of remote sensing technologies. Digiflec offer a mobile mapping service, using our custom built Mobile Mapping Vehicle, which gathers engineering-grade LiDAR data, and other types of data, at travel speed. In mapping, mobile LiDAR data is always geo-referenced to a relevant co-ordinate system.

But what actually is ‘Geospatial Data’?

Let’s break down what “geospatial data” really means.

For data to be called “geospatial,” it simply needs to have a geographical aspect. This means it gives us details about where something is located on or near the Earth’s surface. Think of it like this: geospatial data tells us ‘where’ something exists, ‘what’ feature exists at the location, and the ‘when’ the data was recorded.

Geospatial data is comprised of location, feature, and time.

Why is Geospatially Accurate Data So Important?Digiflec Mobile Data

One of the key features of geospatial data is its ability to be layered and integrated with other types of information. This allows multidimensional analysis, which will give a deeper understanding of the relationships between objects, the physical characteristics of an area, and the various factors which impact upon them.

LiDAR and Air Quality Data Working Together

In their first infrastructure monitoring project, Digiflec installed the first commercial 360° LiDAR system used in the UK to gather information about traffic and road use. The single sensor system served a rural community in Scotland who wanted to understand the impact traffic on a busy road through a small village was having on air quality.

The main focus of the community was to measure particulate matter, since this was the predominant pollutant in the area but the community wants to understand how pollution forms, moves and disperses across the area and beyond. Since particulate matter can be caused by exhaust emissions, data about how the road is used will add a new level of understanding to the air quality data.

To supplement the air quality and weather data being gathered across the network, a Velodyne Puck 360° surround LiDAR sensor, coupled with perception software, was used to monitor the traffic travelling through Thornhill. Cross-referencing the gathered data with the air quality data and weather data allowed an increased understanding of the relationship between these two factors.

Geospatial Data Increases Our Understanding of the World

Geospatial data also offers the ability to layer data gathered at different times to give the most comprehensive and accurate ‘before’ and ‘after’ comparisons possible. For example, roads can be mapped before and after heavy or unusual use, or multiple times to understand how they degrade over time. This information could also be combined with other types of information, such as weather condition data, to understand how this impacts upon the condition of the road surface.

Geospatial data plays a crucial role in understanding the world around us. Its analysis and visualization help in solving complex problems, improving resource management, and making informed decisions across a wide range of industries and sectors.

Digiflec’s Mobile Mapping ServiceMobile Mapping Logo - Digiflec

Digiflec offer a mobile mapping service which gives high-density and highly accurate geospatial data to help you plan infrastructure projects more efficiently, streamline stakeholder communications and mitigate risk. LiDAR-based mapping systems gather geospatial data which is comprised of a collection of co-located charted points that can be recontextured as 3D models.
