The main applications of drone surveying are in:ĭrone surveying generates high-resolution orthomosaic maps and 3D models of areas to create accurate cadastral maps. Drone Surveying Workflow for Onsite Data Collection Image Credits: DJI Enterprize Drone Surveying Workflow-Data Processing Image Credits: DJI Enterprize Applications of Drone Surveying PPK surveying is a GPS correction technology that corrects the location data of the drone only after the complete survey data is collected and uploaded. RTK is a GPS correction technology in which the location data of the drone is provided real-time corrections during the drone surveying and image capturing process. As laying GCPs on the ground is time-consuming and requires labor, vehicles, equipment, and lots of paperwork, techniques like PPK and RTK have been developed. ![]() GCPs enable the drone to return accurate data about its location and the distance it traveled between the two places. GCPs are reference points present in the ground whose coordinates are already known. This can be done either using Ground Control Points (GSPs), Real-Time Kinematic Survey (RTK), or Post Processing Kinematic (PPK) survey.
