Abstract：Research purposes ： The African continent is one of tlie key areas of tlie 11 going out strategy" of China railway construction. However，basic surveying and mapping information of African countries is lack，technical condition is fall behind，natural and traffic conditions are bad，human and social environment is complex，how to obtain the surveying and mapping results quickly and accurately which meet the needs of the railway survey and design，reduce personnel and equipment input，avoid security risks，is task with great concentration of railway technical personnel who participate in such project. The paper used practice of a certain railway survey project in Africa， summarized and analyzed railway construction metliod and technology roadmap of African countries which use China modem railway survey technology. Research conclusions ：The conclusions listed below were drawn in the paper tlirough exemplary cases：(1)The usage of technology and railway survey standard of China in survey and design of the African railway is suitable for the basic situation of Africa counties. (2)The usage of Gauss - Kruger projection coordinate system，satellite mapping and LIDAR technology meets therequirements of surveying and mapping information in all phases of railway design and avoids security risks effectively，which makes up the lack of basic survey information in Africa and the technology gaps between Sino - Africa. (3 ) The survey technical route and method in this paper provide a cerain reference to overseas route engineering survey and design.
