1. A method for generating a building elevation model comprising:
- obtaining sensor data, including location data and inertial sensor data, from each tracked computing device among a plurality of tracked computing devices;
using the sensor data to determine an elevation path for each tracked device;
determining one or more elevation offsets for each elevation path;
correcting each elevation path with the one or more elevation offsets;
generating a building elevation model, the building elevation model comprising information about one or more building features; and
updating the building elevation model with the elevation path of each tracked device.

Abstract
Methods and systems are described for determining the elevation of tracked personnel or assets (trackees) that can take input from mounted sensors on each trackee (including barometric, inertial, magnetometer, radio frequency ranging and signal strength, light and GPS sensors), external constraints (including ranging constraints, feature constraints, and user corrections), and terrain elevation data. An example implementation of this method for determining elevation of persons on foot is described. But this method is not limited to computing elevation of personnel or to on foot movements.
