Abstract: The subject disclosure relates to ways to determine a data collection surveillance cadence. In some aspects, a process of the disclosed technology includes steps for receiving historic map data for one or more geographic regions, wherein each of the one or more geographic regions comprises one or more map features, calculating a change rate for each of the one or more map features, and determining a surveillance cadence for each of the one or more geographic regions based on the change rate for each of the one or more map features. Systems and machine-readable media are also provided.

Abstract: The subject disclosure relates techniques for evaluating map change signals. In some aspects, a process of the disclosed technology includes steps for receiving, at a change detection system, a plurality of change detection signals, wherein each of the change detection signals provides information regarding changes to at least one map feature on a digital map, determining, a relevance value for each of the change detection signals, and prioritizing each of the plurality of change detection signals based on the relevance value for each of the change detection signals. Systems and machine-readable media are also provided.
