    • When transmitting an on-road location on a digital map, an information provider transmits, as on-road location information, string of coordinates information representing the road shape of a road section including the on-road location having a predetermined length, additional information including at least one information item chosen from a group of the attribute information on the road including the road location and detailed information on the nodes in the road section, and relative information indicating the on-road location in the road section. Receiving party receiving this on-road location information performs shape matching to identify the road section on a digital map and uses relative data to identify the on-road location in this road section. The receiving party can identify the road shape with high accuracy even when only a small amount of string of coordinates data is available. This makes it possible to reduce the data transmission amount and identify an on-load location with high accuracy.
    • 当在数字地图上发送道路上的位置时,信息提供者作为道路位置信息发送表示包括具有预定长度的道路位置的道路部分的道路形状的坐标信息字符串,附加信息包括 从包括道路位置的道路上的属性信息组和路段中的节点的详细信息中选择的至少一个信息项以及表示路段中的道路位置的相关信息。 收到该道路位置信息的接收方进行形状匹配以识别数字地图上的道路部分,并使用相对数据来识别该路段中的道路位置。 接收方可以高精度地识别道路形状,即使只有少量坐标数据可用。 这使得可以以高精度降低数据传输量并识别负载位置。

    • A system includes a transmitting apparatus having a first digital map and a receiving apparatus having a second digital map. The second digital map shows a road segment at a different location from the first digital map due to errors. The transmitting apparatus transmits location information to the receiving apparatus. The location information includes coordinates information, attribute information, and relative information. After receiving the location information from the transmitting apparatus, the receiving apparatus identifies the location of a road segment on the second digital map by using the coordinates information and the attribute information and identifies a location of a traffic event on the road segment on the second digital map by using the relative information. The relative information includes a distance from a start point of a road segment on the first digital map to the location on the road segment on the first digital map.
    • 一种系统包括具有第一数字地图的发送装置和具有第二数字地图的接收装置。 由于错误,第二数字地图显示与第一数字地图不同的位置处的路段。 发送装置向接收装置发送位置信息。 位置信息包括坐标信息,属性信息和相关信息。 在从发送装置接收到位置信息之后,接收装置通过使用坐标信息和属性信息来识别第二数字地图上的道路段的位置,并且在第二数字图像上识别道路段上的交通事件的位置 通过使用相关信息映射。 相对信息包括从第一数字地图上的路段的起始点到第一数字地图上道路段上的位置的距离。
