What are the common attribute values ​​for absolute positioning?

The common attribute values ​​​​of absolute positioning are "longitude", "latitude", "altitude", "speed", "direction" and "timestamp": 1. Longitude, indicating that the geographical location is in the east and west The offset in direction relative to the prime meridian; 2. Latitude, indicating the offset of the geographical location relative to the equator in the north-south direction; 3. Altitude, indicating the height of the geographical location relative to sea level; 4. Speed, indicating The moving speed of the object in the geographical location; 5. Direction, indicating the moving direction of the object in the geographical location; 6. Timestamp, indicating the timestamp of the positioning information.

In absolute positioning, commonly used attribute values ​​include:

1. Longitude: represents the offset of the geographical location relative to the prime meridian in the east-west direction . Longitude ranges from -180° to 180°, with positive values ​​for east longitude and negative values ​​for west longitude.

2. Latitude: Indicates the offset of the geographical location relative to the equator in the north-south direction. The latitude range is -90° to 90°, with positive values ​​for northern latitudes and negative values ​​for southern latitudes.

3. Altitude: Indicates the height of a geographical location relative to sea level. Altitude can be positive (above the ground) or negative (below the ground).

4. Speed ​​(speed): Indicates the moving speed of an object in a geographical location. Usually expressed in units such as meters/second or kilometers/hour.

5. Direction (heading): Indicates the moving direction of the object in the geographical location. Usually represented by angle values ​​(0°-360°) or compass directions (north, east, south, west).

6. Timestamp (timestamp): Indicates the timestamp of the positioning information, that is, the time when the positioning information was obtained.

These attribute values ​​can be obtained and processed through technologies such as Global Positioning System (GPS), satellite navigation system, and Geographic Information System (GIS). They play an important role in geolocation services, navigation applications, map displays, etc., and can be used to determine the precise location of a place and other related information.
