Lidar (Light Detection and Ranging) technology has become increasingly popular in recent years due to its ability to accurately measure distances and create detailed 3D models of the environment. Lidar research studies have been conducted across various fields, from archaeology to climate science, and have led to significant advancements in our understanding of the world. In this blog post, we will explore some of the most exciting Lidar research studies that took place from January 2024 to March 2024.

Roman Road Network Spanning the South West Identified in New Research

A Roman road network that spanned Devon and Cornwall and connected significant settlements with military forts across the two counties as well as wider Britannia has been discovered for the first time. Archaeologists at the University of Exeter used laser scans collected as part of the Environment Agency’s National LiDAR Programme to identify new sections of road west of the previously understood boundary. Using sophisticated geographical modelling techniques, they were able to map out the full extent of the network and begin to understand the rationale for its existence. The research was published in the Journal of Computer Applications in Archaeology.

Innovative Aerosol Hygroscopic Growth Study from Mie-Raman-Fluorescence Lidar and Microwave Radiometer Synergy

A study focused on the characterization of aerosol hygroscopicity using remote sensing techniques was published in the journal Atmospheric Measurement Techniques. Researchers employed a Mie-Raman-Fluorescence lidar (LILAS) developed at the ATOLL platform, Laboratoire d’Optique Atmosphérique, Lille, France, in combination with the RPG-HATPRO G5 microwave radiometer to enable continuous aerosol and water vapor monitoring. They identified hygroscopic growth cases when an aerosol layer exhibited an increase in both aerosol backscattering coefficient and relative humidity. By examining the aerosol layer type, determined through a clustering method, the fluorescence backscattering coefficient, which remains unaffected by the presence of water vapor, and the absolute humidity, they verified the homogeneity of the aerosol layer. Consequently, the change in the backscattering coefficient is solely attributed to water uptake. The Hänel theory is employed to describe the evolution of the backscattering coefficient with relative humidity and introduces a hygroscopic coefficient, γ, which depends on the aerosol type. Case studies conducted on July 29 and March 9, 2021 examine respectively an urban and a smoke aerosol layer. For the urban case, γ is estimated as 0.47±0.03 at 532 nm; as for the smoke case, the estimation of γ is 0.5±0.3. These values align with those reported in the literature for urban and smoke particles.

Building Information Modeling (BIM), Blockchain, and LiDAR Applications in Construction Lifecycle: Bibliometric and Network Analysis

A study investigating Industry 4.0 technologies and their impacts on the construction industry was published in the journal Sustainability. The research focused on Building Information Modeling (BIM), Blockchain, and LiDAR applications in the construction lifecycle. A bibliometric analysis of keyword co-occurrence and citations revealed a significant number of publications from 2014 to 2023 investigating the selected technologies. Recent trends indicate that the majority of papers have considered the selected technologies in the integration with each other. However, a specific gap exists in the literature regarding the interactions and potential synergies among these technologies. The gap limits the understanding of how these integrations can address challenges unique to the construction industry and hinders the development of comprehensive solutions. The review has been analyzed and discussed in reference to the type of article, single or multi technologies, the lifecycle, and their applications. The study showed that the integration of BIM, Blockchain, and LiDAR, as a recent trend and as a beneficial solution to automate the whole construction process, has considerable capacities to improve the productivity of the construction industry.


Lidar research studies have led to significant advancements in various fields, from archaeology to climate science to construction. The studies discussed in this blog post demonstrate the versatility and accuracy of Lidar technology in creating detailed 3D models of the environment and providing valuable insights into our understanding of the world. As Lidar technology continues to evolve, we can expect to see even more exciting research studies in the future.
