一种道路数据的处理方法及装置
摘要：
本发明公开了一种道路数据的处理方法及装置，用以解决现有技术中渲染比例尺较大的电子地图的效率较低的问题。该方法获取上下线分离道路的道路数据，将获取到的道路数据中属性及方向相同的道路数据进行连接，得到待处理道路数据，将待处理道路数据中同一上下线分离道路对应的两条待处理道路数据进行合并。上述方法可将电子地图数据库中上下线分离道路对应的两条道路的道路数据合并为一条单线道路的道路数据，合并后的数据量远小于原始数据的数据量，因此，基于合并后的道路数据渲染比例尺较大的电子地图可有效提高电子地图的渲染效率。
摘要（英）：

The invention discloses a road data processing method and device with an aim to solve the problem that rendering electronic maps in large measuring scales is low in efficiency in the prior art. The road data processing method includes acquiring road data of medial-strip roads, connecting the road data with identical attributes and directions from the acquired road data to obtain road data to be processed, and combining road data to be processed of two roads corresponding to the same medial-strip road in the road data to be processed. The road data of the two roads corresponding to the medial-strip roads in an electronic map database are combined into the road data of one single road and data size after combination is much smaller than that of original data, therefore, rendering efficiency of the electronic maps can be effectively improved by rendering the electronic maps in large measuring scales on the basis of the combined road data.
