LocationFix can be used in the following panels: Map.
Schema
| Field | Type | Description |
|---|---|---|
timestamp | time | Time when the message was recorded. |
frame_id | string | Reference frame for the sensor. Latitude and longitude are relative to the origin of this frame. |
latitude | float64 | Latitude in degrees. |
longitude | float64 | Longitude in degrees. |
altitude | float64 | Altitude in meters. |
position_covariance | float64[9] | Position covariance matrix (m²) relative to a tangential plane through the reported position. Components are ENU (East-North-Up) frame, stored in row-major order. |
position_covariance_type | PositionCovarianceType | If position_covariance is available, position_covariance_type must be set to indicate the type of covariance. |
Reference implementations
Foxglove schemas are independent of any specific framework and can be used with any supported message encoding. The schema names should be specified as seen below:
