1. A method for locating an Internet of Things (IoT) network device during an emergency with an emergency information system (E-LIS), comprising:

  • receiving on a server application on a server network device with one or more processors an emergency message or a text-to-911 message from an IoT network device with one or more processors, one or more sensors or one or more actuators and a network connection interface via a communications network indicating an emergency event has occurred,the IoT network device comprising an automated network device capable of automatically sensing its own physical environment to automatically detect the emergency event with the one or more sensors or the one or more actuators without operator input,the one or more sensors or the one or more actuators of the IoT network device automatically detecting an altitude, height, depth, speed, velocity, acceleration, de-acceleration, temperature, moisture, barometric pressure or force-related pressure information from the emergency event,the emergency message and text-to-911 message including current location information for the IoT network device,the current location information including an E-Location Object with Presence Information Data Format (PIDF-LO) information and with Emergency Location-By-Reference (LbR) information, wherein the LbR is a reference key that is used by the server application to determine an actual current location of the IoT network device preventing eavesdropping and preventing modification of the current location information of the IoT network device during sending of the emergency message or the text-to-911 message on the communications network;

    determining on the server application with the LbR the actual current location of the IoT Network device;

    determining from the server application a current set of three-dimensional (3D) (X, Y, Z) geo-space coordinates for the IoT network device with the actual current location information determined with the LbR extracted from the received text-to-911 message or with the actual current location information determined with the LbR extracted from the received emergency message and with other current location information extracted from the received emergency message including audiovisual location information, Global Positioning System (GPS), Wireless Fidelity (Wi-Fi), Wi-Fi Aware, Bluetooth, Near Field Communications (NFC), Machine-to-Machine (M2M) communications, Industrial, Scientific and Medical (ISM), Radio Frequency Identifier (RFID) or cell tower location information collected automatically on the IoT network device while automatically sensing its own physical environment and without operator input;

    determining on the server application with the determined current set of 3D (X, Y, Z) geo-space coordinates a current physical geographic location for the IoT network device;

    sending from the server application an emergency response message or a 911-to-text response message including the determined current physical geographic location for the IoT network device via a second communications network to a desired emergency response server with one or more processors; and

    displaying in real-time on the server network device or another server network device with one or more processors on a graphical map the determined current physical geographic location for the IoT network device for one or more desired emergency response agencies.
