ReadGlossary Terms (7)
Ground Control Points
Surveyed reference targets placed in the scene before photogrammetry or drone survey, used to scale and georeference the output to real-world coordinates.
Orthophoto
A geometrically corrected aerial or terrestrial photograph in which scale is uniform throughout, suitable for precise measurement — unlike a perspective photograph.
Ground Sampling Distance
The size in real-world units (typically cm/px) represented by one pixel in a drone or aerial image — the primary metric for spatial resolution in drone survey.
Drone Survey
The use of an unmanned aerial vehicle (UAV) carrying a camera or sensor to capture data for mapping, photogrammetry or inspection — now standard for inaccessible heritage areas.
Remote Pilot Licence
The DGCA licence required to operate a drone commercially in India — obtained by completing an approved training programme and passing the DGCA examination.
Digital Sky
The DGCA's online platform for drone registration and flight permission — all commercial drone operators in India must register their aircraft and file flight notices here.
DGCA
The Indian government authority that regulates all civil aviation including drones — responsible for the Drone Rules 2021, the Remote Pilot Licence and the Digital Sky platform.
