Glossary

3-D Point Cloud: Points with locational values are connected to create a 3-dimensional model.  

AGI Metashape: Professional data processing software for photogrammetric models. 

Compass Calibration: Orients the drone to its precise location in relation to the earth.

DEM: Digital Elevation Model

Georeferencing: Connects photos with points at the survey site, ensuring data is properly mapped and processed. 

Gimbal: Allows for rotation of the camera while in flight.

GIS: Geographic Information System; ArchGIS is used commonly in archaeology to map information obtained from aerial imaging and context it to archaeological context.

GPR: Ground Penetrating Radar

Ground Control Points: Used to align images during processing.

IMU: Inertial Measurement Unit; it allows drones to balance and have directional awareness - left, right, up, down, etc.

LiDAR: Light detection and ranging. Useful for building 3D models and seeing hidden landscapes.

MAPIR Diffuse Reflectance Standard Calibration Target: A reference panel composed of felt-like material used to calibrate light reflectance. 

Multispectral Imaging: Images captured with cameras that use different light spectrums to visualize the survey area in different ways. Ex.) Near- Infrared and RGB

Orthomosaic:  Created when images obtained during the aerial survey are stitched together to create a seamless model of the site. 

Part 107: FAA Rules and Regulations to pilot a Small Unmanned Aircraft Systems as a Certified Remote Pilot or Commercial Operator.

RTK: Real-Time Kinematic positioning determines the geographical location of the UAV as it flies. 

TRUST:  FAA's The Recreational Use Safety Test

UAV: Unmanned Aerial Vehicle

Vision Sensor:  sensor found on drones for collision avoidance.

WebODM: Cloud-based, open-source data processing software for photogrammetric models.
