Oto, Thanks for replying. The photos are taken using Sony alpha 7R camera equipped on Topcon Falcon 8 UAV. Images are taken at 70m flying altitude at a flying speed of 6m/s (they are not blurry). The GCPs are measured using local base RTK with a 5 second observation at each point. GCPs coordinated in OSGB36 and the EPSG:27700 (OSGB 1936 / British National Grid) spatial reference system is used for AT. GCPs are measured using OSGM15 geoid model, however I cannot find any geoid options in Contextcapture. Would you be able to advise any further? Many thanks
