Abstract
Techniques are described for efficient duplicate label handling. A vector tile is added to a render tree of an electronic map, the vector tile comprising a first set of labels. A vector tile family of the vector tile is identified, each vector tile of the family comprising a second set of labels. For each label of the first set, for each vector tile in the vector tile family, second labels from the second set are identified, and for each identified label, coordinates of the label of the first set are compared to coordinates of the identified label to determine whether the coordinates are within a threshold similarity of each other. Responsive to the determination, the label of the first set of labels is associated with an identifier with which the identified label is associated.
