Lidar is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. Lidar may operate in a fixed direction or it may scan multiple directions, in which case it is known as lidar scanning or 3D laser scanning, a special combination of 3-D scanning and laser scanning. Lidar has terrestrial, airborne, and mobile applications.

Mining in the engineering discipline is the extraction of minerals from the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure.
Leica Geosystems based in eastern Switzerland produces products and systems for surveying and geographical measurement (geomatics). Its products employ a variety of technologies including GPS satellite navigation and laser rangefinders to enable users to model existing structures, terrains in computer based systems to high accuracies, often under 1 cm.
A total station or total station theodolite is an electronic/optical instrument used for surveying and building construction. It is an electronic transit theodolite integrated with electronic distance measurement (EDM) to measure both vertical and horizontal angles and the slope distance from the instrument to a particular point, and an on-board computer to collect data and perform triangulation calculations.
Geologic modelling,geological modelling or geomodelling is the applied science of creating computerized representations of portions of the Earth's crust based on geophysical and geological observations made on and below the Earth surface. A geomodel is the numerical equivalent of a three-dimensional geological map complemented by a description of physical quantities in the domain of interest. Geomodelling is related to the concept of Shared Earth Model; which is a multidisciplinary, interoperable and updatable knowledge base about the subsurface.
Aerial survey is a method of collecting geomatics or other imagery data using airplanes, helicopters, UAVs, balloons, or other aerial methods. Typical data collected includes aerial photography, Lidar, remote sensing and geophysical data. It can also refer to a chart or map made by analyzing a region from the air. Aerial survey should be distinguished from satellite imagery technologies because of its better resolution, quality, and resistance to atmospheric conditions that can negatively impact and obscure satellite observation. Today, aerial survey is often recognized as a synonym for aerophotogrammetry, a part of photogrammetry where the camera is airborne. Measurements on aerial images are provided by photogrammetric technologies and methods.
Hexagon AB is a multinational industrial technology company. Headquartered in Stockholm, Sweden and publicly traded on the Nasdaq Stockholm exchange, the company since 2000 has had a particular focus on measuring technology and geospatial tools and software. After its founding, between 2000 and 2022, Hexagon completed more than 170 acquisitions, and it is the parent company of Leica Geosystems and Infor EAM, among other subsidiaries. With around 24,000 employees, Hexagon's revenue in 2023 was US$5.5 billion, while assets were $18.1 billion.
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important. The GIS software industry encompasses a broad range of commercial and open-source products that provide some or all of these capabilities within various information technology architectures.
3D scanning is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance. The collected data can then be used to construct digital 3D models.
OrthoGraph I is a building survey and floorplan creation application for iOS and Android mobile operating systems, developed by OrthoGraph, a software developer based in Budapest, Hungary. The software can be used to support building information modeling processes.
IMAGINE Photogrammetry is a software application for performing photogrammetric operations on imagery and extracting information from imagery. IMAGINE Photogrammetry is significant because it is a leading commercial photogrammetry application that is used by numerous national mapping agencies, regional mapping authorities, various DOTs, as well as commercial mapping firms. Aside from commercial and government applications, IMAGINE Photogrammetry is widely used in academic research. Research areas include landslide monitoring, cultural heritage studies, and more.
Patent visualisation is an application of information visualisation. The number of patents has been increasing, encouraging companies to consider intellectual property as a part of their strategy. Patent visualisation, like patent mapping, is used to quickly view a patent portfolio.
Mountains is an image analysis and surface metrology software platform published by the company Digital Surf. Its core is micro-topography, the science of studying surface texture and form in 3D at the microscopic scale. The software is dedicated to profilometers, 3D light microscopes ("MountainsMap"), scanning electron microscopes ("MountainsSEM") and scanning probe microscopes ("MountainsSPIP").
Digital Surf is a French software company formed in 1989 mainly known for its Mountains software, that is offered as embedded or optional OEM surface analysis software by the majority of profilometer and microscope manufacturers.
Geosoft Incorporated is a software development and services company headquartered in Toronto, Canada. The company provides geophysical and geological software and geospatial server technology for professional geoscientists involved in natural resource exploration and related earth science disciplines.
CloudCompare is a 3D point cloud processing software. It can also handle triangular meshes and calibrated images.
Digital archaeology is the application of information technology and digital media to archaeology. It includes the use of digital photography, 3D reconstruction, virtual reality, and geographical information systems, among other techniques. Computational archaeology, which covers computer-based analytical methods, can be considered a subfield of digital archaeology, as can virtual archaeology.
Dietmar Müller is a professor of geophysics at the school of geosciences, the University of Sydney.
Geological structure measurement by LiDAR technology is a remote sensing method applied in structural geology. It enables monitoring and characterisation of rock bodies. This method's typical use is to acquire high resolution structural and deformational data for identifying geological hazards risk, such as assessing rockfall risks or studying pre-earthquake deformation signs.
