1. A method comprising:
obtaining movement path data that specifies a location of a mobile article over time within a geographical area having an infrastructure feature;
determining based on map data and based on the movement path data calibrated location data of the mobile article, wherein the determining based on map data and based on the movement path data calibrated location data of the mobile article includes using map data that specifies coordinate location data of the infrastructure feature, wherein the method includes collecting crowdsourced movement path data of a plurality of articles other than the mobile article representing movement of the plurality of articles through a location proximate the infrastructure feature to provide collected historical movement path data defining a plurality of collected historical movement paths, wherein the determining based on map data and based on the movement path data the calibrated location data of the mobile article includes providing a dissimilarity score between the movement path data that specifies a location of a mobile article over time within a geographical area having an infrastructure feature and reference movement path data defined by the plurality of collected historical movement paths; and
providing one or more output based on the determining, wherein the one or more output includes an output to send a notification to a user interface.
