Abstract: Embodiments include apparatus and methods for modeling air flow from flight responses in aerial vehicles. Sensor data is received for aerial vehicles in a geographic area. The pose (e.g., roll, pitch, and yaw) of the aerial vehicles is calculated from the sensor data. One or more wind vectors are calculated based, at least in part, on the pose. An air flow model is generated from the wind vectors.

Abstract: Described is a method, performed by at least one apparatus, that includes obtaining a plurality of radio fingerprints, the radio fingerprints including information on radio nodes or signals from radio nodes observed by mobile devices and corresponding location estimates; and identifying, among said radio nodes, those radio nodes which are mobile radio nodes and which belong to a respective public transport vehicle, at least by relating movement information of a respective mobile radio node. The movement information is determined based on said obtained radio fingerprints, with public transport route information.

Abstract: Inter-alia, a method is disclosed comprising: obtaining one or more pieces of radio environment information representing a first radio environment of a first area that is covered by one or more radio units; obtaining or determining a location estimate; obtaining one or more pieces of reference radio environment information representing a second radio environment of a second area; and determining a trustworthiness information indicative of a degree of similarity between the first radio environment represented by the one or more pieces of radio environment information and the second radio environment represented by the one or more pieces of reference radio environment information. It is further disclosed an according apparatus, computer program and system.

Abstract: Inter-alia, a method is disclosed comprising: obtaining one or more first fallback objects indicative of a geographic area that is covered by one or more cells of a communication network; obtaining one or more pieces of cell information indicative of a number of positioning requests that a respective cell of the one or more cells has received; determining one or more second fallback objects out of the one or more fallback objects; determining for an area of the respective second fallback object in that the needed level of accuracy for determining a position is not achievable, one or more cells based at least partially on the one or more pieces of cell information; and outputting the determined one or more second fallback objects and/or the determined one or more cells for usage in a generation of a radio map. It is further disclosed an according apparatus, computer program and system.

Abstract: A method, apparatus, and computer program product are described herein for determining public transportation use. Methods may include receiving probe data points associated with movement of a plurality of people; associating the movement of the plurality of people with a public transit route having a plurality of public transit stop locations; determining, from the probe data points associated with movement of the plurality of people, transit stop locations at which people board a public transit vehicle associated with the public transit route; determining, from the probe data points associated with movement of the plurality of people, transit stop locations at which people exit the public transit vehicle; calculating, from the probe data points associated with the movement of the plurality of people, a number of people boarding the public transit vehicle at each respective transit stop location and a number of people exiting at each respective transit stop location.
