Hero Image for How Weather Really Affects LiDAR Performance LiDAR technology employs light to measure distances with remarkable precision. Short for Light Detection and Ranging, this remote sensing method sends out laser pulses and measures their return time after bouncing off objects. The result creates detailed three-dimensional representations of environments.
Located on the southernmost coast of Sweden, Ystad is a popular region known for its shallow sandy beaches and thriving tourism. However, its exposure to strong winds and waves across the Baltic Sea makes it particularly vulnerable to coastal erosion.
Along the coast of Maine, USA, communities are facing increasing pressure from storm-driven erosion and rising sea levels. The region is home to sensitive ecosystems, such as habitats for endangered piping plovers, and its economy depends heavily on both tourism and the health of its coastal environment.
In information analysis, measurements, and classification, especially with LiDAR solutions like those from YellowScan, the terms "accuracy" and "precision" are often confused. Although they have distinct meanings, both are essential for evaluating solution performance in fields such as UAV-based LiDAR mapping and machine learning.
LiDAR technology sends out hundreds of thousands of laser pulses each second. It achieves impressive accuracy between 2.5 and 10 centimeters in surveyed areas. This precision makes it a great way to get data for creating detailed 3D point clouds that serve applications of all types, from geology to urban planning.
LiDAR (Light Detection and Ranging) serves as the life-blood of modern navigation systems. It provides precise spatial measurements through an elegant yet powerful operational principle. Unlike passive sensing technologies, LiDAR actively emits laser pulses toward objects and measures the reflection time back to the sensor. This time-of-flight measurement helps calculate exact distances using the formula d = (c × Δt) / 2, where c represents light speed and Δt indicates the time delay.
LiDAR accuracy is the life-blood of reliable spatial data acquisition. The basic concept shows how close a LiDAR measurement comes to the actual real-life value. At the time professionals discuss LiDAR accuracy, they express it as a range (±2cm) or as a standard deviation (3cm to 1σ).
We’re surrounded by raw data—from customer clicks online to 3D landscapes captured by laser scanning devices like LiDAR. Every day, vast volumes of information flow from sensors, online sales, customer surveys, or the LiDAR systems YellowScan offers.

Frontier Precision faced a critical challenge when their long-term client, the Alaska Department of Transportation (DOT), needed to rapidly and accurately map the area affected by the Mendenhall Glacier flood in Juneau, Alaska.
This article compares two popular technologies for creating 3D models and maps: photogrammetry and LiDAR. The focus lies on key differences between both: how they work, the different outputs created for each, and popular use cases. The article finishes with a discussion of why investing in LiDAR can be a better choice, despite higher costs.
The University of Vermont (UVM) in the USA became involved in this project through its connections with the Vermont Geological Survey (VGS) and the Vermont Agency of Transportation (VTrans). UVM is one of the few organizations in the state with access to UAS LiDAR technology, making it a priority contact for capturing accurate elevation data and models for landslides, especially when rapid data collection was required.
This article explains what LiDAR point clouds are and how they are used for 3D mapping applications. Learn the basics of LiDAR point clouds!
LiDAR scanners are used for capturing 3D point clouds. But how do they work? This and more are explained in the article below, which covers the operating principle of different LiDAR scanners and explains how distance measurements are transformed and combined into 3D point clouds. These provide the basis for many 3D mapping products used for different industry applications.
A LiDAR drone is an unmanned aerial vehicle (UAV) equipped with Light Detection and Ranging (LiDAR) sensors. A LiDAR is an active sensor that uses inertial measurement to correlate where it is on the earth’s surface, resulting in a direct measurement of the earth.
European Hamsters are a protected species living in agricultural areas, often alongside field mice, which are considered pests. Lack of awareness about hamster presence leads to unintentional harm by farmers, endangering the European Hamster population.
In the realm of environmental monitoring and analysis, the accurate assessment of vegetation plays a crucial role in understanding ecosystems. Drones equipped with advanced imaging technologies have revolutionized this process by providing efficient and precise data collection methods.
