IDENTIFYING MISSING FEATURES IN DIGITAL MAPS BASED ON MOBILE TELEMETRY DATA

A method for identifying missing map features in an electronic map, involving receiving telemetry probes indicating a geographic location of a mobile computing device, and identifying a subset of telemetry probes corresponding to an existing map feature. The identified subset is then removed from an aggregation of telemetry probes, and the remaining telemetry probes used to generate a density map and identify missing clusters of telemetry probes. A geometry of the missing clusters is determined, and a missing map feature defined from the geometry of the missing cluster. An electronic map may be updated with the missing map feature.
