Abstract: Classic method of Global Mapper and direct method of coordinate transformation are the two main methods for bulk importing coordinate data of mining rights area into Google Earth.Aiming at improving work efficiency,these two methods are compared in terms of convenience and steps in operation,numbers and sizes of required softwares and etc,and summarizes key findings that direct method is the more convenient way in bulk importing mining rights area coordinate data with advantage of fewer softwares and in smaller sizes,which is more conducive to improving work efficiency.

Key words: Google Earth maps,mining right,coordinate data
