Light Detection and Ranging (LiDAR) is a remote sensing technology that uses laser light to measure the distance between the sensor and the target. It is used in a variety of applications, such as surveying, mapping, and navigation. LiDAR data can be used to create 3D models of terrain, buildings, and other objects. To make the most of this data, you need the right software tools.
In this article, we will explore some of the best free and commercial LiDAR software tools available. QGIS 3 is an open-source software for 3D point cloud visualization. It can handle LAS and LAZ files without needing to transform them into an intermediate format. QGIS 3 also allows you to symbolize point clouds based on class, height, and RGB attributes.
However, it does not have many tools for analyzing LiDAR data. SAGA GIS is another open-source software that can be used to import LiDAR data into the application. It has options for updating color ramps and changing the value at which you want to display your LiDAR data. However, it does not have any 3D visualization capabilities. GRASS GIS is a powerful open-source GIS software with a wide range of tools for geospatial data management, geoprocessing, spatial modeling, and visualization. It can be used to import LiDAR data and visualize it in 2D or 3D.
However, it does not have any native tools for transforming LAS files into 3D views. ArcGIS is a commercial GIS software with powerful tools for geospatial data management, geoprocessing, spatial modeling, and visualization. It also has a range of tools for analyzing LiDAR data. LidarViewer Pro is a dedicated LiDAR data processing application that allows you to process your data quickly and easily. It has intuitive tools for visualizing and analyzing LiDAR data in 2D or 3D. An individual license costs 1500 EUR (about 1800 USD).The LP360 geospatial product line is another commercial software for processing LiDAR data or images captured from any aircraft or mobile sensor.
It has powerful tools for analyzing large LiDAR datasets and extracting valuable information from them. These are some of the best free and commercial LiDAR software tools available. Each one has its own strengths and weaknesses, so it's important to choose the right one for your needs.
