Abstract: The invention addresses the problem of efficiently locating a target device such as a mobile phone, by directing the movement of moveable wireless beacons along a search pattern, using the target device as a moveable wireless beacon detection device. Preferably, the target device is equipped with a WiFi and/or Bluetooth radio and the moveable wireless beacons are WiFi-equipped and/or Bluetooth-equipped mobile phones in possession of first responders. To locate a target device, the WiFi and/or Bluetooth radios in the moveable wireless beacons are activated such that they transmit a unique identifier. As moveable wireless beacons report their locations and as the target device reports updated beacon detection information, movement directions are determined and sent to the moveable wireless beacons to coordinate an efficient search of the target device.

Abstract: A method for processing two different types of geographic address data sets to establish candidate matched data includes entering address data into the system and accessing a point level address data set. A determination is made if the point level data set contains an exact match to the entered address data. Any exact address data match from the point level data set is output. Candidate address data matches from the point level data set are saved when no exact match is determined as existing in the point level data set. A centerline address data set is accessed and a determination is made of candidate address data matches from the centerline address data set. Candidate address data from both the point level data set and the centerline data set are scored and matched. A system for geocoding and address hygiene includes a processing system with an input and an output system coupled to said processing system. A point level data set is coupled to the processing system.

Abstract: A system and method of determining elevation values includes inputting a location into a geocoding system having a segment data set and determining the closest segment in the data set to the location. A data set of elevation data the closest segment is accessed and a determination is made of an elevation value for each of two elevation points associated with the closest segment. The elevation value of the location is determined based on interpolation of the location in relation to each the two elevation points and the elevation value of each of the two elevation points. The determined elevation value for said input location is output. The offset distance of the location from the closest segment may be determined and a slope applied to the offset distance to determine an elevation gain or loss for the location due to the offset distance of the location from the closest segment.
