地图坐标（车道+距离s） Map coordinates (lane ID + distance s)

Used in: Position, map.LaneOverlap

• int32 lane_id = 1

  车道id Lane ID

• double s = 2

  s是车道上的点到车道起点的距离 s is the distance from the point on the lane to the starting point of the lane

经纬度矩形区域 latitude and longitude rectangular area

• double min_longitude = 1

  最小经度 minimum longitude

• double min_latitude = 2

  最小纬度 minimum latitude

• double max_longitude = 3

  最大经度 maximu longitude

• double max_latitude = 4

  最大纬度 minimum longitude

WGS84经纬度坐标 WGS84 longitute and latitude coordinates

Used in: Position

• double longitude = 1

  经度 longitude

• double latitude = 2

  纬度 latitude

• optional double z = 3

  高程（单位：米） elevation (unit: meters)

坐标，如果多种坐标同时存在，两两之间必须满足映射关系，同时逻辑坐标是必须提供的 Coordinates, if multiple coordinates exist at the same time, the mapping relationship between them must be satisfied, and logical coordinates must be provided.

Used in: agent.Agent, agent.Trip

• optional LanePosition lane_position = 1

  地图坐标AOI Map coordinates AOI (one of these must be provided)

• optional LongLatPosition longlat_position = 2

  WGS84经纬度坐标 WGS84 longitute and latitude coordinates

• optional XYPosition xy_position = 3

  XY坐标 XY coordinates

XY坐标 XY coordinates

Used in: agent.AgentState, Position, map.Polyline, map.RoadConnection, map.RoadEdge, map.RoadLine

• double x = 1

  x坐标，单位米，对应经度 x coordinate, in meters, corresponding to longitude

• double y = 2

  y坐标，单位米，对应纬度 y coordinate, in meters, corresponding to latitude

• optional double z = 3

  z坐标，单位米，对应高程 z coordinate, in meters, corresponding to elevation
