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.
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally produced relief maps. A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs.

Aerial photography is the taking of photographs from an aircraft or other airborne platforms. When taking motion pictures, it is also known as aerial videography.
Konica Minolta, Inc. is a Japanese multinational technology company headquartered in Marunouchi, Chiyoda, Tokyo, with offices in 49 countries worldwide. The company manufactures business and industrial imaging products, including copiers, laser printers, multi-functional peripherals (MFPs) and digital print systems for the production printing market. Konica Minolta's Managed Print Service (MPS) is called Optimised Print Services. The company also makes optical devices, including lenses and LCD film; medical and graphic imaging products, such as X-ray image processing systems, colour proofing systems, and X-ray film; photometers, 3-D digitizers, and other sensing products; and textile printers. It once had camera and photo operations inherited from Konica and Minolta but they were sold in 2006 to Sony, with Sony's Alpha series being the successor SLR division brand.
Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.
Aerial archaeology is the study of archaeological remains by examining them from a higher altitude. In present day, this is usually achieved by satellite images or through the use of drones.
Bathymetry is the study of underwater depth of ocean floors, lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago.
Aerial survey is a method of collecting geomatics or other imagery by using airplanes, helicopters, UAVs, balloons or other aerial methods. Typical types of data collected include aerial photography, Lidar, remote sensing and also geophysical data (such as aeromagnetic surveys and gravity. It can also refer to the chart or map made by analysing a region from the air. Aerial survey should be distinguished from satellite imagery technologies because of its better resolution, quality and atmospheric conditions. Today, aerial survey is sometimes recognized as a synonym for aerophotogrammetry, part of photogrammetry where the camera is placed in the air. Measurements on aerial images are provided by photogrammetric technologies and methods.
Soil survey, or soil mapping, is the process of classifying soil types and other soil properties in a given area and geo-encoding such information.
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.
Pictometry International is an aerial measurement company based in Henrietta, New York that develops software that uses three-dimensional aerial photographs to view high-resolution images of buildings in their entirety. Pictometry International's technology was developed at the Rochester Institute of Technology and shows structures at an oblique angle or at a 45-degree angle, from all sides providing perspective and overhead shot images that are accurate to 1/100th of an inch. The company has 80 Cessnas that provide high-resolution aerial photography in counties that include 95 percent of the U.S. population.
Aerofilms Ltd was the UK's first commercial aerial photography company, founded in 1919 by Francis Wills and Claude Graham White. Wills had served as an Observer with the Royal Naval Air Service during World War I, and was the driving force behind the expansion of the company from an office and a bathroom in Hendon to a business with major contracts in Africa and Asia as well as in the UK. Co-founder Graham-White was a pioneer aviator who had achieved fame by making the first night flight in 1910.
Cyclomedia is a Dutch company specialising in the large-scale and systematic visualisation of environments based on 360° panoramic photographs (Cycloramas). Using specialised technology, large public areas are photographed and stored in an online database. Overlapping panoramic images are captured at 5-meter intervals from public roads at street level, with the camera system mounted on a moving car.
Velodyne Lidar is a Silicon Valley-based lidar technology company, headquartered in San Jose, California. It was spun off from Velodyne Acoustics in 2016. As of July 2020, the company has had about 300 customers. Velodyne Lidar ships sensors to mobility industry customers for testing and commercial use in autonomous vehicles, advanced driver assistance systems, mapping, robotics, infrastructure and smart city applications. In February 2023, the company merged with Ouster.
Nearmap is an aerial technology company headquartered in Australia that provides frequently-updated, high-resolution aerial imagery and location intelligence on up to 95% of Australia's population, 80% of the United States population, 75% of the New Zealand population, and 66% of Canada's population. It was a publicly traded company on the Australian Securities Exchange until being taken private by Thoma Bravo in 2022.
Pteryx UAV was a Polish Miniature Unmanned Aerial Vehicle (UAV) designed for civilian use. It was manufactured and sold by Trigger Composites. The machine was both a flying remote control (RC) model and pre-programmed vehicle. It was awarded the Innowator Podkarpacia medal for innovative design in the category of micro-enterprises of the Podkarpacie region in 2010.
Mobile mapping is the process of collecting geospatial data from a mobile vehicle, typically fitted with a range of GNSS, photographic, radar, laser, LiDAR or any number of remote sensing systems. Such systems are composed of an integrated array of time synchronised navigation sensors and imaging sensors mounted on a mobile platform. The primary output from such systems include GIS data, digital maps, and georeferenced images and video.
A digital outcrop model (DOM), also called a virtual outcrop model, is a digital 3D representation of the outcrop surface, mostly in a form of textured polygon mesh.
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.
