1. A method for detecting a point of interest, the method comprising: receiving location information associated with a first plurality of mobile devices in a geographic region; determining a concentration of mobile devices from among the first plurality based on identifying a second plurality of mobile devices associated with the concentration, wherein the first plurality of mobile devices includes the second plurality of mobile devices and additional mobile devices not in the determined concentration, wherein the second plurality is based on mobile devices that are identified as stationary and/or located within the geographic region for a specified period of time; processing select location information associated with the second plurality of mobile devices to determine one or more fixed location points in the geographic region which points include the determined concentration of mobile devices; collecting three-dimensional data obtained using a Light Detection and Ranging (LIDAR) detector by transmitting laser beams in a survey zone, wherein the collected three dimensional data include data representing a plurality of features in the survey zone; accessing the three-dimensional data representing the one or more determined fixed location points as coinciding with the survey zone from a geographic database comprising the collected three-dimensional data; processing the accessed three-dimensional data to determine one or more features from the plurality of features in the survey zone and associated with the one or more fixed location points, wherein the determined one or more features are indicative of a presence of one or more candidate points of interest in the geographic region; and determining the one or more candidate points of interest based, at least in part, on the determined one or more features.
