1. A computer-implemented method comprising:
receiving a drilling trajectory plan to drill an intended trajectory;
analyzing the drilling trajectory plan and identifying a tool face orientation to drill the intended trajectory based on the drilling trajectory plan;
identifying an uncertainty level associated with the tool face orientation based on a data structure storing uncertainty levels at different tool face orientations;
determining a drilling plan based on the uncertainty level associated with the tool face orientation; and
outputting a visual representation that includes the tool face orientation and the uncertainty level associated therewith.
