【摘要】 Google Maps的开放策略为WebGIS的应用开发提供方便的平台。针对具有特殊需求的路径规划、行车诱导等应用,在深入分析路网组成及寻径特点的基础上,探讨如何根据Google Maps API提取局部交通地理数据的策略,并提出以探索法进行提取的算法思路。更多还原

【Abstract】 The open policy which Google Maps adopted provides application development of WebGIS a convenient platform. Aiming at some special applications, such as path planning and traffic inducing, deeply analyzes the traffic network features and path searching methods which Google Maps employed, examines the policy of abstracting local traffic data using those APIs provided by Google Maps, and puts forward the algorithm of heuristic method to get traffic data. Abstracting local traffic data using those APIs provided by Google Maps, and puts forward the algorithm of heuristic method to get traffic data.更多还原
