latitude is the latitude to set longitude is the longitude to set
Definition at line 12 of file GeoPosition.cpp.
Member Function Documentation
| float bearing | ( | GeoPosition | from ) |
Get the bearing from the specified origin position to this position.
To get relative bearing, subtract the result from your heading.
- Parameters:
-
from is the position from which to calculate bearing
- Returns:
- the bearing in degrees
Definition at line 88 of file GeoPosition.cpp.
| float distance | ( | GeoPosition | from ) |
Get the distance from the specified origin position to this position.
- Parameters:
-
from is the position from which to calculate distance
- Returns:
- the distance in meters
Definition at line 138 of file GeoPosition.cpp.
| int getTimestamp | ( | void | ) |
Return a previously set timestamp on the position.
- Returns:
- the timestamp (e.g., seconds, milliseconds, etc.)
Definition at line 191 of file GeoPosition.cpp.
| double latitude | ( | ) |
Get the position's latitude.
- Returns:
- the position's latitude
Definition at line 26 of file GeoPosition.cpp.
| double longitude | ( | ) |
Get the position's longitude.
- Returns:
- the position's longitude
Definition at line 31 of file GeoPosition.cpp.
| void move | ( | float | course, |
| float | distance | ||
| ) |
Move the location of the position by the specified distance and in the specified direction.
- Parameters:
-
course is the direction of movement in degrees, absolute not relative distance is the distance of movement along the specified course in meters
Definition at line 54 of file GeoPosition.cpp.
| void set | ( | double | latitude, |
| double | longitude | ||
| ) |
Set the position's location to the specified coordinates.
- Parameters:
-
latitude is the new latitude to set longitude is the new longitude to set
Definition at line 36 of file GeoPosition.cpp.
| void set | ( | GeoPosition | pos ) |
Set the position's location to another position's coordinates.
- Parameters:
-
pos is another position from which coordinates will be copied
Definition at line 42 of file GeoPosition.cpp.
| void setTimestamp | ( | int | time ) |
Set an arbitrary timestamp on the position.
- Parameters:
-
timestamp is an integer timestamp, eg., seconds, milliseconds, or whatever
Definition at line 187 of file GeoPosition.cpp.
