# LGF_GpsToGpsDD (FC / 3.0.2)

Overview

Author: Siemens Digital Industry

## Short description

This function converts a given GPS data type (format direction, degrees, minutes, and seconds) into a GPS-DD data type (decimal degrees).

GPS "native" to GPS decimal Degree.

### Block Interface

## User defined datatype(s)

### LGF_typeGPS (UDT / V3.0.1)

Datatype for GPS Coordinates Latitude and Longitude.
Child Datatypes in Degree, Minutes, Seconds and the Direction.
Datatype for a whole GPS Data set.

Identifier | Data type | Default value | Description
--- | --- | --- | ---
latitude | LGF_typeGPS_DMS | --- | Latitude child element
longitude | LGF_typeGPS_DMS | --- | Longitude child element

### LGF_typeGPS_DMS (UDT / V3.0.1)

Datatype for GPS Coordinates in Degree, Minutes, Seconds and the Direction.

dir | Char | '' | Direction [N, S, E, W, n, s, e, w]
deg | UInt | 0 | Degrees, Latitude [-89..+ 89]; Longitude [-179..+179]
min | UInt | 0 | Minutes [0..+59]
sec | UInt | 0 | Seconds [0..+59]

### LGF_typeGPS_DD (UDT / V3.0.1)

Datatype for GPS Coordinates in decimal degrees.
For latitude and longitude.
Datatype for a whole GPS Data set.

Identifier | Data type | Default value | Description
--- | --- | --- | ---
latitude | Real | 0.0 | Degrees latitude with decimal places (Unit: degree decimal), North = positive; South = negative) valid value range [-90.00000..90.00000]
longitude | Real | 0.0 | Degrees longitude in degrees with decimal places (Unit: degree decimal), East = positive; West = negative) valid range [-180.0000..180.0000]
