Determining location using multi-source geolocation data

A system comprising:

• one or more computer processors;
• one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the system to perform operations comprising:
• accessing new location data from a location source of a plurality of location sources, the new location data comprising a new position and an accuracy of the new position;
• determining a current position and an accuracy of the current position based on the new position, the accuracy of the new position, a previous current position, and an accuracy of the previous current position;
• determining a change in location based on a difference between the current position and the previous current position;
• in response to the new location data comprising a new altitude value, setting a current altitude value with the new altitude value;
• and
• in response to the new location data not comprising the new altitude value,
• setting a current altitude value to a previous current altitude value based on the change in location being less than a first threshold and the previous current altitude value not being a null altitude value, and
• setting the current altitude value with the null altitude value based on the change in location not being less than the first threshold.

A non-transitory computer-readable storage medium including instructions that, when processed by a computer, configure the computer to perform operations comprising:

• accessing new location data from a location source of a plurality of location sources, the new location data comprising a new position and an accuracy of the new position;
• determining a current position and an accuracy of the current position based on the new position, the accuracy of the new position, a previous current position, and an accuracy of the previous current position;
• determining a change in location based on a difference between the current position and the previous current position;
• determining that the new location data does not comprise a new altitude value;
• setting a current altitude value to a previous current altitude value based on the change in location being less than a first threshold and the previous current altitude value not being a null altitude value;
• and
• setting the current altitude value with the null altitude value based on the change in location transgressing the first threshold.
