1. Method of identifying a traffic management feature from an oblique image comprising:
determining coordinates of corners of a region of interest from an aerial image;
determining an oblique image region of interest from the oblique image based on the coordinates;
determining an estimated height of the traffic management feature;
generating bounding box pixels for the traffic management feature within the oblique image region of interest; and
calculating coordinates of the traffic management feature based on a homography transform based on the estimated height and the traffic management feature bounding box pixels.
