 This study investigated the repeatability of high-resolution digital surface models, DSMs, generated using real-time kinematic, RTK, enabled drones. Three different block control configurations were tested, GPS ground control points, GCPs, camera stations only, and camera stations plus one GCP. The results showed that the first and third configurations provided the best DSM inner consistency with an average range of elevation differences of 6 cm, 2.5 GSD, ground sampling density, for a 10 cm resolution DSM. When using camera stations only, the average range was almost doubled, 4.7 GSD. Additionally, the average DSM accuracy, which was verified on checkpoints, was found to be approximately 2.1 GSD with the first and third configurations, and 3.7 GSD with camera stations only.
