Device-based geospatial filtering for barometric pressure sensor calibration

A method comprising:

• determining, by a processor of a mobile device, a location of the mobile device;
• transmitting the location from the mobile device to a server;
• generating, by one or more processors of the server, a gridded geospatial filter map of a geographical area that encompasses the location of the mobile device, wherein the gridded geospatial filter map indicates a first region that is not conducive to calibrating a barometric pressure sensor of the mobile device and a second region that is conducive to calibrating the barometric pressure sensor, the gridded geospatial filter map is a 2D grid tile, and the first region and the second region include sub-tiles of the gridded geospatial filter map;
• transmitting the gridded geospatial filter map from the server to the mobile device;
• determining, by the processor of the mobile device, whether the location is conducive to calibrating the barometric pressure sensor based on the location being encompassed by one of the sub-tiles of the gridded geospatial filter map;
• when the one of the sub-tiles is in the second region, the processor of the mobile device sending to the server calibration data generated by the barometric pressure sensor, and the one or more processors of the server calibrating the barometric pressure sensor using the calibration data;
• and
• when the one of the sub-tiles is in the first region, the processor of the mobile device causing the calibration data not to be used.
