Techniques for identifying and classifying distribution network transient pressure events comprising receiving time series pressure data from a plurality of sensors in a system. Identifying, based at least in part on the time series pressure data, a pressure change in a portion of the system. Generating, based at least in part on the identifying of the pressure change, a severity score associated with the pressure change. Determining that the severity score is greater than or equal to a threshold. Based at least in part on the severity score being greater than or equal to the threshold, generating a transient pressure event and displaying descriptive information identifying the transient pressure event and one or more response tools for responding to the transient pressure event.

Described herein are techniques to enable a mobile device to perform multi-source estimation of an altitude for a location. A baseline altitude may be determined at ground level for a location and used to calibrate a barometric pressure sensor on the mobile device. The calibrated barometric pressure sensor can then estimate changes in altitude relative to ground level based on detected pressure differentials, allowing a relative altitude to ground to be determined. Baseline calibration for the barometric sensor calibration can be performed to determine an ambient ground-level barometric pressure.
