Location Information Servers rely on signal surveys to create a
signal map allowing for subsequent device location determination.
This document describes a method by which a Survey Device is able to
provide indoor location related measurement data to a LIS for
positioning purposes. Location related measurement information
comprises observations concerning properties related to the position
of a Survey Device and the radio, electromagnetic, and other
observable environmental measures as perceived by the Survey Device.
These measurements could be data about Wi-Fi signals, Bluetooth
signals, barometric pressure, or any other environmental measurement
which could sent to a LIS for subsequent processing to help determine
the location of devices that later enter the venue. A basic set of
location-related measurements, data rights disclosure and location
types are defined.
