GEOExplorerIQ Data Types

The concept of a Data Type is very important in GEOExplorerIQ. Data Types are properties of each sensor that represent the various measurements parameters that are available for that sensor. Data Types vary depending on the type of sensor, but they are displayed and handled the same way in all parts of GEOExplorerIQ. Examples of Data Types are displacements, velocities, battery voltage, and many others.

 

All of the available Data Types for a sensor can be displayed by clicking on the sensor name in the sensor list.  Data Types also appear as the columns for views of the Systems Pages

 

The following table lists and describes the most common Data Types used for sensors in GEOExplorerIQ.  

 

Not all sensors will have all of these data types and not all data types have been included.  Please refer to the Sensor Reference for details of each individual sensor type.

 

Data Type

Description

Name

This is the user defined name of the sensor. It can be edited in the sensor settings dialog for each sensor.

Serial Number

This is a unique identifier for each device. Typically the serial number will be marked on the physical device. This is often the MAC address or other similar ID for the device.

Source IP Address

The IP address of the sensor on the network. Note that the IP address could be the one provided by the device (depending on the hardware model) or it could be the IP address that data is received from. In the later case this could be the IP address of the router/firewall or, if the unit is a 900Mhz mesh device, it could be the address of the mesh gateway.

Interface Type

Specifies the network interface type. This could be WiFi, Ethernet, 900Mhz, or Serial Port. This field may be set to '--' if the unit firmware does not yet support sending the connection type with the raw data stream.

RSSI

The Receive Signal Strength Indicator for the radio signal. This can be very useful to help diagnose connection issues. Please note: This shows the signal strength of packets RECEIVED by the device. It's possible that the device can receive a strong signal from an access point, but that there isn't enough power to return the signal TO the access point, so this should not be considered an absolute measure of signal strength.

Firmware Version

The version of the firmware loaded on this device. You should try to make sure that all sensors in a system are using the most recent firmware version when possible. Please contact your support team if you believe a firwmare update is required.

Input Voltage

The voltage of the battery or power supply that is powering the device.

Input Current

The total electrical current being consumed by the device.

Temperature

In many cases this is shows the internal temperature of the device main circuit board. This is typically a few degrees warmer than the outside temperature. For weather stations and other environmental sensors the temperature data type is used for the environmental temperature measurement.

Satellites

The number of satellites the a device fitted with a GPS receiver has a lock on. A number lower than 6 may indicate problems with the location where the device is installed.

Measured Northing

The Northing (Local Coordinates) of the sensor.

Measured Easting

The Easting (Local Coordinates) of the sensor.

Measured Elevation

The Elevation (Local Coordinates) of the sensor.

Delta Northing

This is the difference between the Northing (Local Coordinates) of the current measurement and the Northing of the Last Reset Measurement.

Delta Easting

This is the difference between the Easting (Local Coordinates) of the current measurement and the Easting of the Last Reset Measurement.

Delta Elevation

This is the difference between the Elevation (Local Coordinates) of the current measurement and the Elevation of the Last Reset Measurement. This is the same as Vertical Displacement.

Hz Displacement

This is the two dimensional distance between the horizontal position (Local Coordinates Northing and Easting) of the current measurement and the horizontal position of the Last Reset Measurement.

Vt Displacement

This is the difference between the Elevation (Local Coordinates) of the current measurement and the Elevation of the Last Reset Measurement. This is the same as Delta Elevation.

3D Displacement

This is the distance between the 3D Position (Local Coordinates Northing, Easting, and Elevation) of the current measurement and the 3D Position of the Last Reset Measurement.

SD Displacement

This is the difference between the current Slope Distance and the Slope Distance of the Last Reset Measurement.

3 PT Velocity

The system takes the last 3 measurements and calculates linear regressions through the Local Northing, Easting, and Elevation components of the coordinates. These individual velocities are combined to determine a 3D velocity for the 3 data points.  

Deprecated please use Point Vel 1 instead.

12 PT Velocity

Same as the 3PT Velocity, but using 12 data points for additional smoothing.

Deprecated please use Point Vel 2 instead.

3 PT Inverse Velocity

Inverse of 3PT Velocity.

Deprecated please use Point 1/Vel 1 instead.

12 PT Inverse Velocity

Inverse of 12PT Velocity.

Deprecated please use Point 1/Vel 2 instead.

3D Point Vel 1

The system takes the last N measurements and calculates linear regressions through the Local Northing, Easting, and Elevation components of the coordinates. These individual velocities are combined to determine a 3D velocity for the data points. The number of points used in the calculation can be defined in the sensor's settings dialog.

3D Point Vel 2

This datatype is identical to 3D Point Vel 1, but can be configured with a different number of points.

3D Point 1/Vel 1

Inverse of 3D Point Vel 1.

3D Point 1/Vel 2

Inverse of 3D Point Vel 2.

3D Period Vel 1

The system pulls all measurements for the latest N hours and calculates linear regressions through the Local Northing, Easting, and Elevation components of the coordinates. These individual velocities are combined to determine a 3D velocity for the data points. The number of hours of data used in the calculation can be defined in the sensor's settings dialog..

3D Period Vel 2

This datatype is identical to 3D Period Vel 1, but can be configured with a different number of hours.

3D Period 1/Vel 1

Inverse of 3D Period Vel 1.

3D Period 1/Vel 2

Inverse of 3D Period Vel 2.

ENV Raw Data Age

The elapsed time since a packet of environmental data (Battery Voltage, Temperature, Etc) has been received.

Raw Data Age

This is the amount of time that has passed since the last raw data packet was received from this device.

ENV Measurement Age

This is the amount of time that has passed since the last ENV measurement was stored in the database.

Measurement Age

This is the amount of time that has passed since the last measurement was stored in the database. Hint: It is a good idea to set Alarm Triggers on this Data Type in order to monitor outages.

Acceleration

The velocity is calculated for the current period based on user defined parameters, then compared to the previous period calculated using the same parameters. The magnitude of change in velocity between the current calculation and the previous observation equals the Acceleration.
