The unmanned aerial photogrammetric survey is the use of unmanned aerial vehicles (UAVs) to take photos for use in photogrammetry, the science of making measurements from photographs. Instruments manufactured for UAVs could be mounted on unmanned flying platforms of various sizes and types, such as octocopters .
Typical data collected includes aerial photography, Lidar, remote sensing (using various visible and invisible bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet) and geophysical data (such as aeromagnetic surveys and gravity measurements). It can also refer to a chart or map made by analyzing a region from the air.
OpenDroneMap is an open source photogrammetry toolkit to process aerial imagery (usually from a drone) into maps and 3D models. [3] [4] [5] The software is hosted and distributed freely on GitHub. [6] OpenDroneMap has been integrated within American Red Cross's in-field Portable OpenStreetMap system. [7]
PrecisionHawk is a manufacturer of drones (Lancaster) and has more recently focused heavily on developing software for aerial data analysis (DataMapper) and drone safety systems (LATAS). PrecisionHawk is a member of the U.S. Federal Aviation Administration Pathfinder Initiative and the NASA UTM Program.
The LAS (LASer) format is a file format designed for the interchange and archiving of lidar point cloud data. It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The format is widely used [1] and regarded as an industry standard for lidar data.

Pix4D is a Swiss software company that specializes in terrestrial and drone photogrammetry mapping software. It was founded in 2011 as a spinoff from the École Polytechnique Fédérale de Lausanne (EPFL) Computer Vision Lab in Switzerland. [ 1 ]
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
