Abstract
A technique for displaying labels on a digital map comprise displaying the digital map via a user interface at a first zoom level, including displaying non-overlapping labels. The method also comprises receiving, via the user interface, a request to zoom out from the digital map to a second zoom level, where the second zoom level corresponds to smaller magnification than the first zoom level, and where the plurality of labels have the same size at the first zoom level and the second zoom level. Still further, the method includes resolving collisions among the plurality of labels at the second zoom level in response to receiving the request and prior to zooming out from the first zoom level, and zooming out from the digital map at the first zoom level to the second zoom level via at least one intermediate zoom level.
