Get Location (G Dataflow)

Version:
Last Modified: March 15, 2017

Returns the last calculated latitude, longitude, and altitude of the device's onboard GPS receiver.

Note  

You must connect an external GPS antenna to the device and set the device's external time reference to GPS in order to receive valid data from this function. For best results, allow the GPS receiver to complete a self survey before reading the location.

instrument handle in

The instrument handle that you obtain from Initialize.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

instrument handle out

The instrument handle that you obtain from Initialize.

error out

Error information.

The node produces this output according to standard error behavior.

datatype_icon

latitude

The current latitude, in degrees, of the connected device's GPS receiver.

Negative values represent southern latitudes. Positive values represent northern latitudes.

datatype_icon

longitude

The current longitude, in degrees, of the connected device's GPS receiver.

Negative values represent western longitudes. Positive values represent eastern longitudes.

datatype_icon

altitude

The current altitude, in meters, of the connected device's GPS receiver using the WGS-84 earth ellipsoid standard.
