Systems and techniques for determining more accurate predicted object trajectories are disclosed. A vehicle computing system may determine an initial predicted trajectory for an object detected in the environment and determine a predicted location for the object at the endpoint of the trajectory. Using a feature map of the environment, the vehicle computing system may refine endpoint location based on a context for the endpoint. The system then determines a middle point of the trajectory based on the refined endpoint location and refines the middle location further based on the context for that location. Subsequent intermediate points and contexts along the trajectory may be iteratively used for further location refinements, generating a refined and more accurate predicted object trajectory for the object that can then be used to determine trajectories for controlling a vehicle.
