3S在线路勘测中的应用

APPHICATION 3S METHOD ON ROUTE SURVEY

针对线路勘测的特点，探讨以3S为主体的现代测绘新技术在线路勘测的应用中，如何从线路勘测实际需要出发，优化设计方案，调整数据采集与表达方式。通过数据处理，建立符合计算机辅助设计模式的数字高程模型，满足线路计算机辅助设计的需要。

According to the characters of route survey to optimize design schemes and data collecting methods using 3S modern survey technology of route survey. After data beinghandled, the Digtal Elevation Model could be made.It could meets the needs of CAD in route survey.
