摘要

•Processed ∼38,000 images acquired by the Dawn spacecraft to determine Ceres’ shape.•High-resolution global shape of Ceres was determined using stereophotoclinometry.•Highly accurate spin-pole axis and rotation rate of Ceres were determined.•The average height error of the final global Ceres topography model is about 10 m.•About 89% of the Ceres topography model has the total height error below 20 m.
