An approach is provided for determining a vehicle parking event and respective characteristics using sensor data. The approach, for example, involves receiving sensor data from at least one sensor associated with a mobile device in a vehicle. The approach also involves processing the sensor data to determine a sequence of semantic events. The semantic events respectively indicate a maneuver performed by the vehicle. The approach further involves processing the sensor data to determine a distance estimation over which at least one of the semantic events is performed. The approach further involves detecting a parking event of the vehicle, a characterization of the parking event, or a combination thereof based on the sequence of semantic events and the distance estimation. The approach further involves providing the parking event, the characterization of the parking event, or a combination thereof as an output.

Embodiments provide for a method of determining a geospatial position of a point of interest and a portable positioning device. In one embodiment, the method includes collecting data from a receiving unit and data from at least one of an imaging device and an IMU of the positioning device for each one of a plurality of positions of the positioning device. The collected data is then transmitted to a data fusing processor for determining orientations and positions of the positioning device for the plurality of positions in a global coordinate system. Further, the method includes obtaining a pointing input including a sighting direction towards the point of interest from the positioning device being positioned at at least one reference position. The pointing input is transmitted to the data fusing processor for identifying the point of interest and for determining the geospatial position of the point of interest in the global coordinate system.

In certain embodiments, a mobile device includes a sensor, one or more processors, and a memory. The memory stores computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including determining a first geographic location based on wireless signals received as part of a wireless-based mobile device positioning system. The operations include accessing a geographic database that includes data representing a number of geographic locations and properties associated with the geographic locations, and a mapping between measureable values of a type and particular geographic locations. The operations include determining, using the geographic database, candidate geographic locations for adjusting the first geographic location. The operations include accessing a particular value of the type determined according to a measurement of the sensor and determining a second geographic location based on the candidate geographic locations and on the particular value and the mapping.

A method of inferring the GPS location of a device with a GPS receiver is disclosed. The method includes using signals from two GPS satellites to determine two candidate GPS locations. Geographic information can be used to estimate the probability that the device is at each location. If one of the two candidate GPS locations has a substantially higher probability of being the correct location, that location may be selected as the inferred GPS location. The method may also include making use of additional sensed data that could be provided using sensors onboard the device.
