Abstract
A method for labeling line features in an electronic map involves updating a labeling of a previously rendered map view to obtain a labeling for a current map view, including obtaining candidate line features associated with the current map view, and for a candidate line feature of the candidate line features, making a determination that a label associated with the candidate line feature is unique in the current map view. The method further involves, based on the determination, identifying at least one visible span of the candidate line feature, and based on the at least one visible span, obtaining ranked candidate positions for the label. The method also includes selecting, from the ranked candidate positions, a position for the label in the current map view, and rendering a frame for a display, the frame comprising the current map view, the candidate line features, and the label at the position.
