Abstract:

Abstract: Navigation points are batch inputted to handheld GPS by manual input navigation point one by one in the traditional geochemical sweep work.This method is not only inefficient but also easy to make mistakes.Through repeated practice，we develop one method which using MapGIS，Notepad，"GPS" help，MapSource and other software to generate exchange format GPX file of MapSource data，and then achieve the goal of fast and efficient batch input to the handheld GPS waypoint data.Destinations verification had proved the feasibility of the method.The method does not require programming，it is practical，can not only reduce human error，but also improve the work efficiency，bring great convenience to the geological field work.

Key words: Geochemical Exploration, Data, Batch, Import, MapGIS, “GPS help”
