Introduction to GCPs and Drone Photography
Ground control points (GCPs) play a crucial role in generating accurate maps in the field of drone photography. In this article, we will explore the use of GCPs with drone photography, especially in conjunction with Real-Time Kinematic (RTK) technology. We will also examine the benefits of using GCPs with RTK technology to achieve superior mapping accuracy.
Setting Up Ground Control Points (GCPs)
Accurate geographic locations are of utmost importance when it comes to setting up GCPs for mapping outputs. It is essential to choose the right EPSG code, which is a shorthand for a specific spatial reference system, to ensure accurate results. Surveyors use GNSS receivers or GPS systems to physically mark these control points on the ground, usually with nails, wooden posts, or other monuments.
Using Aerial Targets for GCPs
Aerial targets can be used to capture data and tie it to GCPs in drone photography. These targets provide a visual reference for the GCPs in the captured data. By utilizing aerial targets, drone pilots can ensure accurate mapping outputs by linking the visual data captured during the flight to the physical location of the GCPs. Various equipment, such as drones capable of following automated flight missions, ground control point aerial targets, and control maps, are necessary for capturing data with GCPs.

Advantages of GCPs over RTK Capable Drones
Using GCPs offers several advantages over using RTK capable drones. Cost-effectiveness is a significant advantage, as GCPs provide accurate mapping without the need for expensive RTK equipment. GCPs also enhance positioning and accuracy of mapping outputs, although RTK data may have higher accuracy. By opting for GCPs, drone operators can avoid the substantial expense associated with RTK capable drones.
Data Processing Software for GCP Alignment
Various data processing software options are available for aligning GCPs in drone photography. DroneDeploy and Pix4D Mapper are popular choices for GCP alignment. These software applications allow users to accurately align GCPs with the orthomosaic model. Proper GCP alignment is crucial for achieving accurate mapping results.
